149 is a movie player for Linux (runs on many other platforms and CPU
150 architectures, see the documentation).
151 It plays most MPEG/\:VOB, AVI, ASF/\:WMA/\:WMV, RM, QT/\:MOV/\:MP4, Ogg/\:OGM,
152 MKV, VIVO, FLI, NuppelVideo, yuv4mpeg, FILM and RoQ files, supported by many
153 native and binary codecs.
154 You can watch VCD, SVCD, DVD, 3ivx, DivX 3/4/5, WMV and even H.264 movies,
157 MPlayer supports a wide range of video and audio output drivers.
158 It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, libcaca, DirectFB,
159 Quartz, Mac OS X CoreVideo, but you can also use GGI, SDL (and all their drivers),
160 VESA (on every VESA-compatible card, even without X11), some low-level
161 card-specific drivers (for Matrox, 3dfx and ATI) and some hardware MPEG decoder
162 boards, such as the Siemens DVB, Hauppauge PVR (IVTV), DXR2 and DXR3/\:Hollywood+.
163 Most of them support software or hardware scaling, so you can enjoy movies in
166 MPlayer has an onscreen display (OSD) for status information, nice big
167 antialiased shaded subtitles and visual feedback for keyboard controls.
168 European/\:ISO8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean
169 fonts are supported along with 12 subtitle formats (MicroDVD, SubRip, OGM,
170 SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub, PJS and our own: MPsub) and
171 DVD subtitles (SPU streams, VOBsub and Closed Captions).
174 (MPlayer's Movie Encoder) is a simple movie encoder, designed to encode
175 MPlayer-playable movies (see above) to other MPlayer-playable formats (see
177 It encodes to MPEG-4 (DivX/Xvid), one of the libavcodec codecs and
178 PCM/\:MP3/\:VBRMP3 audio in 1, 2 or 3 passes.
179 Furthermore it has stream copying abilities, a powerful filter system (crop,
180 expand, flip, postprocess, rotate, scale, noise, RGB/\:YUV conversion) and
184 is MPlayer with a graphical user interface.
185 It has the same options as MPlayer.

503 .\" Configuration files
504 .\" --------------------------------------------------------------------------
506 .SH "CONFIGURATION FILES"
507 You can put all of the options in configuration files which will be read
508 every time MPlayer/MEncoder is run.
509 The system-wide configuration file 'mplayer.conf' is in your configuration
510 directory (e.g.\& /etc/\:mplayer or /usr/\:local/\:etc/\:mplayer), the user
511 specific one is '~/\:.mplayer/\:config'.
512 The configuration file for MEncoder is 'mencoder.conf' in your configuration
513 directory (e.g.\& /etc/\:mplayer or /usr/\:local/\:etc/\:mplayer), the
514 user specific one is '~/\:.mplayer/\:mencoder.conf'.
515 User specific options override system-wide options and options given on the
516 command line override either.
517 The syntax of the configuration files is 'option=<value>', everything after
518 a '#' is considered a comment.
519 Options that work without values can be enabled by setting them to 'yes'
520 or '1' or 'true' and disabled by setting them to 'no' or '0' or 'false'.
521 Even suboptions can be specified in this way.
523 You can also write file-specific configuration files.
524 If you wish to have a configuration file for a file called 'movie.avi', create a file
525 named 'movie.avi.conf' with the file-specific options in it and put it in
527 You can also put the configuration file in the same directory as the file to
528 be played, as long as you give the \-use\-filedir\-conf option (either on the
529 command line or in your global config file).
531 .I EXAMPLE MPLAYER CONFIGURATION FILE:
534 # Use Matrox driver by default.

630 .SH "GENERAL OPTIONS"
633 .B \-codecs\-file <filename> (also see \-afm, \-ac, \-vfm, \-vc)
634 Override the standard search path and use the specified file
635 instead of the builtin codecs.conf.
638 .B \-include <configuration file>
639 Specify configuration file to be parsed after the default ones.
643 Prints all available options.
646 .B \-msgcharset <charset>
647 Convert console messages to the specified character set (default: autodetect).
648 Text will be in the encoding specified with the \-\-charset configure option.
649 Set this to "noconv" to disable conversion (for e.g.\& iconv problems).
652 The option takes effect after command line parsing has finished.
653 The MPLAYER_CHARSET environment variable can help you get rid of
654 the first lines of garbled output.
658 Enable colorful console output on terminals that support ANSI color.
661 .B \-msglevel <all=<level>:<module>=<level>:...>
662 Control verbosity directly for each module.
663 The 'all' module changes the verbosity of all the modules not
664 explicitly specified on the command line.
665 See '\-msglevel help' for a list of all modules.
668 Some messages are printed before the command line is parsed and are
669 therefore not affected by \-msglevel.
670 To control these messages you have to use the MPLAYER_VERBOSE environment
671 variable, see its description below for details.
687 informational messages
689 status messages (default)
703 Prepend module name in front of each console message.
706 .B \-noconfig <options>
707 Do not parse selected configuration files.
710 If \-include or \-use\-filedir\-conf options are
711 specified at the command line, they will be honoured.
713 Available options are:
717 all configuration files
718 .IPs "gui (GUI only)"
719 GUI configuration file
721 system configuration file
723 user configuration file
729 Make console output less verbose; in particular, prevents the status line
730 (i.e.\& A: 0.7 V: 0.6 A-V: 0.068 ...) from being displayed.
731 Particularly useful on slow terminals or broken ones which do not properly
732 handle carriage return (i.e.\& \\r).
735 .B \-priority <prio> (Windows and OS/2 only)
736 Set process priority for MPlayer according to the predefined
737 priorities available under Windows and OS/2.
738 Possible values of <prio>:
740 idle|belownormal|normal|abovenormal|high|realtime
745 Using realtime priority can cause system lockup.
749 .B \-profile <profile1,profile2,...>
750 Use the given profile(s), \-profile help displays a list of the defined profiles.
753 .B \-really\-quiet (also see \-quiet)
754 Display even less output and status messages than with \-quiet.
755 Also suppresses the GUI error message boxes.
758 .B \-show\-profile <profile>
759 Show the description and content of a profile.
762 .B \-use\-filedir\-conf
763 Look for a file-specific configuration file in the same directory as
764 the file that is being played.
767 May be dangerous if playing from untrusted media.
771 Increment verbosity level, one level for each \-v
772 found on the command line.
776 .SH "PLAYER OPTIONS (MPLAYER ONLY)"
779 .B \-autoq <quality> (use with \-vf [s]pp)
780 Dynamically changes the level of postprocessing depending on the available spare
782 The number you specify will be the maximum level used.
783 Usually you can use some big number.
784 You have to use \-vf [s]pp without parameters in order for this to work.
787 .B \-autosync <factor>
788 Gradually adjusts the A/V sync based on audio delay measurements.
789 Specifying \-autosync 0, the default, will cause frame timing to be based
790 entirely on audio delay measurements.
791 Specifying \-autosync 1 will do the same, but will subtly change the A/V
792 correction algorithm.
793 An uneven video framerate in a movie which plays fine with \-nosound can
794 often be helped by setting this to an integer value greater than 1.
795 The higher the value, the closer the timing will be to \-nosound.
796 Try \-autosync 30 to smooth out problems with sound drivers which do
797 not implement a perfect audio delay measurement.
798 With this value, if large A/V sync offsets occur, they will only take about
799 1 or 2 seconds to settle out.
800 This delay in reaction time to sudden A/V offsets should be the only
801 side-effect of turning this option on, for all sound drivers.
805 Prints some statistics on CPU usage and dropped frames at the end of playback.
806 Use in combination with \-nosound and \-vo null for benchmarking only the
810 With this option MPlayer will also ignore frame duration when playing
811 only video (you can think of that as infinite fps).
814 .B \-colorkey <number>
815 Changes the colorkey to an RGB value of your choice.
816 0x000000 is black and 0xffffff is white.
817 Only supported by the cvidix, fbdev, svga, vesa, winvidix, xmga, xvidix,
818 xover, xv (see \-vo xv:ck), xvmc (see \-vo xv:ck) and directx video output
823 Disables colorkeying.
824 Only supported by the cvidix, fbdev, svga, vesa, winvidix, xmga, xvidix,
825 xover, xv (see \-vo xv:ck), xvmc (see \-vo xv:ck) and directx video output
829 .B \-correct\-pts (EXPERIMENTAL)
830 Switches MPlayer to an experimental mode where timestamps for video frames
831 are calculated differently and video filters which add new frames or
832 modify timestamps of existing ones are supported.
833 The more accurate timestamps can be visible for example when playing
834 subtitles timed to scene changes with the \-ass option.
835 Without \-correct\-pts the subtitle timing will typically be off by some frames.
836 This option does not work correctly with some demuxers and codecs.
839 .B \-crash\-debug (DEBUG CODE)
840 Automatically attaches gdb upon crash or SIGTRAP.
841 Support must be compiled in by configuring with \-\-enable\-crash\-debug.
844 .B \-doubleclick\-time
845 Time in milliseconds to recognize two consecutive button presses as
846 a double-click (default: 300).
847 Set to 0 to let your windowing system decide what a double-click is
851 You will get slightly different behaviour depending on whether you bind
852 MOUSE_BTN0_DBL or MOUSE_BTN0\-MOUSE_BTN0_DBL.
855 .B \-edlout <filename>
856 Creates a new file and writes edit decision list (EDL) records to it.
857 During playback, the user hits 'i' to mark the start or end of a skip block.
858 This provides a starting point from which the user can fine-tune EDL entries
860 See http://www.mplayerhq.hu/\:DOCS/\:HTML/\:en/\:edl.html for details.
863 .B \-enqueue (GUI only)
864 Enqueue files given on the command line in the playlist instead of playing them
869 Enforces a fixed video system for multiple files (one (un)initialization for
871 Therefore only one window will be opened for all files.
872 Currently the following drivers are fixed-vo compliant: gl, gl2, mga, svga, x11,
873 xmga, xv, xvidix and dfbmga.
876 .B \-framedrop (also see \-hardframedrop, experimental without \-nocorrect\-pts)
877 Skip displaying some frames to maintain A/V sync on slow systems.
878 Video filters are not applied to such frames.
879 For B-frames even decoding is skipped completely.
883 Enable or disable the GUI interface (default depends on binary name).
884 Only works as the first argument on the command line.
885 Does not work as a config-file option.
888 .B \-h, \-help, \-\-help
889 Show short summary of options.
892 .B \-hardframedrop (experimental without \-nocorrect\-pts)
893 More intense frame dropping (breaks decoding).
894 Leads to image distortion!
895 Note that especially the libmpeg2 decoder may crash with this,
896 so consider using "\-vc ffmpeg12,".
900 Command that is executed every 30 seconds during playback via system() -
901 i.e.\& using the shell.
904 MPlayer uses this command without any checking, it is your responsibility
905 to ensure it does not cause security problems (e.g.\& make sure to use full
906 paths if "." is in your path like on Windows).
908 This can be "misused" to disable screensavers that do not support the proper
909 X API (also see \-stop\-xscreensaver).
910 If you think this is too complicated, ask the author of the screensaver
911 program to support the proper X APIs.
913 .I EXAMPLE for xscreensaver:
914 mplayer \-heartbeat\-cmd "xscreensaver\-command \-deactivate" file
916 .I EXAMPLE for GNOME screensaver:
917 mplayer \-heartbeat\-cmd "gnome\-screensaver\-command \-p" file
923 Shorthand for \-msglevel identify=4.
924 Show file parameters in an easily parseable format.
925 Also prints more detailed information about subtitle and audio
926 track languages and IDs.
927 In some cases you can get more information by using \-msglevel identify=6.
928 For example, for a DVD it will list the chapters and time length of each title,
929 as well as a disk ID.
930 Combine this with \-frames 0 to suppress all output.
931 The wrapper script TOOLS/\:midentify.sh suppresses the other MPlayer output and
932 (hopefully) shellescapes the filenames.
935 .B \-idle (also see \-slave)
936 Makes MPlayer wait idly instead of quitting when there is no file to play.
937 Mostly useful in slave mode where MPlayer can be controlled
938 through input commands.
941 .B \-input <commands>
942 This option can be used to configure certain parts of the input system.
943 Paths are relative to ~/.mplayer/.
946 Autorepeat is currently only supported by joysticks.
948 Available commands are:
953 Specify input configuration file other than the default
954 ~/\:.mplayer/\:input.conf.
955 ~/\:.mplayer/\:<filename> is assumed if no full path is given.
957 Device to be used for Apple IR Remote (default is autodetected, Linux only).
959 Delay in milliseconds before we start to autorepeat a key (0 to disable).
961 Number of key presses to generate per second on autorepeat.
963 Prints all keys that can be bound to commands.
965 Prints all commands that can be bound to keys.
967 Specifies the joystick device to use (default: /dev/\:input/\:js0).
969 Read commands from the given file.
970 Mostly useful with a FIFO.
973 When the given file is a FIFO MPlayer opens both ends so you can do
974 several 'echo "seek 10" > mp_pipe' and the pipe will stay valid.
979 .B \-key\-fifo\-size <2\-65000>
980 Specify the size of the FIFO that buffers key events (default: 7).
981 A FIFO of size n can buffer (n\-1) events.
982 If it is too small some events may be lost
983 (leading to "stuck mouse buttons" and similar effects).
984 If it is too big, MPlayer may seem to hang while it
985 processes the buffered events.
986 To get the same behavior as before this option was introduced,
987 set it to 2 for Linux or 1024 for Windows.
990 .B \-lircconf <filename> (LIRC only)
991 Specifies a configuration file for LIRC (default: ~/.lircrc).
994 .B \-list\-properties
995 Print a list of the available properties.
999 Loops movie playback <number> times.
1003 .B \-menu (OSD menu only)
1004 Turn on OSD menu support.
1007 .B \-menu\-cfg <filename> (OSD menu only)
1008 Use an alternative menu.conf.
1011 .B \-menu\-chroot <path> (OSD menu only)
1012 Chroot the file selection menu to a specific location.
1017 .IPs "\-menu\-chroot /home"
1018 Will restrict the file selection menu to /\:home and downward (i.e.\& no
1019 access to / will be possible, but /home/user_name will).
1024 .B \-menu\-keepdir (OSD menu only)
1025 File browser starts from the last known location instead of current directory.
1028 .B \-menu\-root <value> (OSD menu only)
1029 Specify the main menu.
1032 .B \-menu\-startup (OSD menu only)
1033 Display the main menu at MPlayer startup.
1036 .B \-mouse\-movements
1037 Permit MPlayer to receive pointer events reported by the video
1039 Necessary to select the buttons in DVD menus.
1040 Supported for X11 based VOs (x11, xv, xvmc, etc.) and the gl, gl2, direct3d and
1045 Turns off AppleIR remote support.
1048 .B \-noconsolecontrols
1049 Prevent MPlayer from reading key events from standard input.
1050 Useful when reading data from standard input.
1051 This is automatically enabled when \- is found on the command line.
1052 There are situations where you have to set it manually, e.g.\&
1053 if you open /dev/\:stdin (or the equivalent on your system), use stdin
1054 in a playlist or intend to read from stdin later on via the loadfile or
1055 loadlist slave commands.
1059 Turns off joystick support.
1063 Turns off LIRC support.
1067 Disable mouse button press/\:release input (mozplayerxp's context menu relies
1072 Turns on usage of the Linux RTC (realtime clock \- /dev/\:rtc) as timing
1074 This wakes up the process every 1/1024 seconds to check the current time.
1075 Useless with modern Linux kernels configured for desktop use as they already
1076 wake up the process with similar accuracy when using normal timed sleep.
1079 .B \-playing\-msg <string>
1080 Print out a string before starting playback.
1081 The following expansions are supported:
1084 Expand to the value of the property NAME.
1086 Expand TEXT only if the property NAME is available.
1088 Expand TEXT only if the property NAME is not available.
1092 .B \-playlist <filename>
1093 Play files according to a playlist file (ASX, Winamp, SMIL, or
1094 one-file-per-line format).
1097 This option is considered an entry so options found after it will apply
1098 only to the elements of this playlist.
1100 FIXME: This needs to be clarified and documented thoroughly.
1103 .B \-rtc\-device <device>
1104 Use the specified device for RTC timing.
1108 Play files in random order.
1111 .B \-skin <name> (GUI only)
1112 Loads a skin from the directory given as parameter below the default skin
1113 directories, /usr/\:local/\:share/\:mplayer/\:skins/\: and ~/.mplayer/\:skins/.
1118 .IPs "\-skin fittyfene"
1119 Tries /usr/\:local/\:share/\:mplayer/\:skins/\:fittyfene
1120 and afterwards ~/.mplayer/\:skins/\:fittyfene.
1125 .B \-slave (also see \-input)
1126 Switches on slave mode, in which MPlayer works as a backend for other programs.
1127 Instead of intercepting keyboard events, MPlayer will read commands separated
1128 by a newline (\\n) from stdin.
1131 See \-input cmdlist for a list of slave commands and DOCS/tech/slave.txt
1132 for their description.
1136 Time frames by repeatedly checking the current time instead of asking the
1137 kernel to wake up MPlayer at the correct time.
1138 Useful if your kernel timing is imprecise and you cannot use the RTC either.
1139 Comes at the price of higher CPU consumption.
1143 Skip <sec> seconds after every frame.
1144 The normal framerate of the movie is kept, so playback is accelerated.
1145 Since MPlayer can only seek to the next keyframe this may be inexact.
1149 .SH "DEMUXER/STREAM OPTIONS"
1153 Select the Dynamic Range Compression level for AC-3 audio streams.
1154 <level> is a float value ranging from 0 to 1, where 0 means no compression
1155 and 1 (which is the default) means full compression (make loud passages more
1156 silent and vice versa).
1157 This option only shows an effect if the AC-3 stream contains the required range
1158 compression information.
1161 .B \-aid <ID> (also see \-alang)
1162 Select audio channel (MPEG: 0\-31, AVI/\:OGM: 1\-99, ASF/\:RM: 0\-127,
1163 VOB(AC-3): 128\-159, VOB(LPCM): 160\-191, MPEG-TS 17\-8190).
1164 MPlayer prints the available audio IDs when run in verbose (\-v) mode.
1165 When playing an MPEG-TS stream, MPlayer/\:MEncoder will use the first program
1166 (if present) with the chosen audio stream.
1169 .B \-ausid <ID> (also see \-alang)
1170 Select audio substream channel.
1171 Currently the valid range is 0x55..0x75 and applies only to MPEG-TS when handled
1172 by the native demuxer (not by libavformat).
1173 The format type may not be correctly identified because of how this information
1174 (or lack thereof) is embedded in the stream, but it will demux correctly the
1175 audio streams when multiple substreams are present.
1176 MPlayer prints the available substream IDs when run with \-identify.
1179 .B \-alang <language code[,language code,...]> (also see \-aid)
1180 Specify a priority list of audio languages to use.
1181 Different container formats employ different language codes.
1182 DVDs use ISO 639-1 two letter language codes, Matroska, MPEG-TS and NUT
1183 use ISO 639-2 three letter language codes while OGM uses a free-form identifier.
1184 MPlayer prints the available languages when run in verbose (\-v) mode.
1189 .IPs "mplayer dvd://1 \-alang hu,en"
1190 Chooses the Hungarian language track on a DVD and falls back on English if
1191 Hungarian is not available.
1192 .IPs "mplayer \-alang jpn example.mkv"
1193 Plays a Matroska file in Japanese.
1198 .B \-audio\-demuxer <[+]name> (\-audiofile only)
1199 Force audio demuxer type for \-audiofile.
1200 Use a '+' before the name to force it, this will skip some checks!
1201 Give the demuxer name as printed by \-audio\-demuxer help.
1202 For backward compatibility it also accepts the demuxer ID as defined in
1203 libmpdemux/\:demuxer.h.
1204 \-audio\-demuxer audio or \-audio\-demuxer 17 forces MP3.
1207 .B \-audiofile <filename>
1208 Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a
1212 .B \-audiofile\-cache <kBytes>
1213 Enables caching for the stream used by \-audiofile, using the specified
1217 .B \-reuse\-socket (udp:// only)
1218 Allows a socket to be reused by other processes as soon as it is closed.
1221 .B \-bandwidth <value> (network only)
1222 Specify the maximum bandwidth for network streaming (for servers that are
1223 able to send content in different bitrates).
1224 Useful if you want to watch live streamed media behind a slow connection.
1225 With Real RTSP streaming, it is also used to set the maximum delivery
1226 bandwidth allowing faster cache filling and stream dumping.
1230 This option specifies how much memory (in kBytes) to use when precaching a
1232 Especially useful on slow media.
1239 .B \-cache\-min <percentage>
1240 Playback will start when the cache has been filled up to <percentage>
1244 .B \-cache\-seek\-min <percentage>
1245 If a seek is to be made to a position within <percentage> of the cache size
1246 from the current position, MPlayer will wait for the cache to be filled to
1247 this position rather than performing a stream seek (default: 50).
1250 .B \-cdda <option1:option2> (CDDA only)
1251 This option can be used to tune the CD Audio reading feature of MPlayer.
1253 Available options are:
1257 .IPs paranoia=<0\-2>
1259 Values other than 0 seem to break playback of anything but the first track.
1261 0: disable checking (default)
1263 1: overlap checking only
1265 2: full data correction and verification
1267 .IPs generic-dev=<value>
1268 Use specified generic SCSI device.
1269 .IPs sector-size=<value>
1270 Set atomic read size.
1271 .IPs overlap=<value>
1272 Force minimum overlap search during verification to <value> sectors.
1274 Assume that the beginning offset of track 1 as reported in the TOC will be
1276 Some Toshiba drives need this for getting track boundaries correct.
1277 .IPs toc-offset=<value>
1278 Add <value> sectors to the values reported when addressing tracks.
1281 (Never) accept imperfect data reconstruction.
1285 .B \-cdrom\-device <path to device>
1286 Specify the CD-ROM device (default: /dev/\:cdrom).
1289 .B \-channels <number> (also see \-af channels)
1290 Request the number of playback channels (default: 2).
1291 MPlayer asks the decoder to decode the audio into as many channels as
1293 Then it is up to the decoder to fulfill the requirement.
1294 This is usually only important when playing videos with AC-3 audio (like DVDs).
1295 In that case liba52 does the decoding by default and correctly downmixes the
1296 audio into the requested number of channels.
1297 To directly control the number of output channels independently of how many
1298 channels are decoded, use the channels filter.
1301 This option is honored by codecs (AC-3 only), filters (surround) and audio
1302 output drivers (OSS at least).
1304 Available options are:
1318 .B \-chapter <chapter ID>[\-<endchapter ID>] (dvd:// and dvdnav:// only)
1319 Specify which chapter to start playing at.
1320 Optionally specify which chapter to end playing at (default: 1).
1323 .B \-cookies (network only)
1324 Send cookies when making HTTP requests.
1327 .B \-cookies\-file <filename> (network only)
1328 Read HTTP cookies from <filename> (default: ~/.mozilla/ and ~/.netscape/)
1329 and skip reading from default locations.
1330 The file is assumed to be in Netscape format.
1334 audio delay in seconds (positive or negative float value)
1336 Negative values delay the audio, and positive values delay the video.
1337 Note that this is the exact opposite of the \-audio\-delay MEncoder option.
1340 When used with MEncoder, this is not guaranteed to work correctly
1341 with \-ovc copy; use \-audio\-delay instead.
1345 Ignore the specified starting time for streams in AVI files.
1346 In MPlayer, this nullifies stream delays in files encoded with
1347 the \-audio\-delay option.
1348 During encoding, this option prevents MEncoder from transferring
1349 original stream start times to the new file; the \-audio\-delay option is
1351 Note that MEncoder sometimes adjusts stream starting times
1352 automatically to compensate for anticipated decoding delays, so do not
1353 use this option for encoding without testing it first.
1356 .B \-demuxer <[+]name>
1358 Use a '+' before the name to force it, this will skip some checks!
1359 Give the demuxer name as printed by \-demuxer help.
1360 For backward compatibility it also accepts the demuxer ID as defined in
1361 libmpdemux/\:demuxer.h.
1364 .B \-dumpaudio (MPlayer only)
1365 Dumps raw compressed audio stream to ./stream.dump (useful with MPEG/\:AC-3,
1366 in most other cases the resulting file will not be playable).
1367 If you give more than one of \-dumpaudio, \-dumpvideo, \-dumpstream
1368 on the command line only the last one will work.
1371 .B \-dumpfile <filename> (MPlayer only)
1372 Specify which file MPlayer should dump to.
1373 Should be used together with \-dumpaudio / \-dumpvideo / \-dumpstream.
1376 .B \-dumpstream (MPlayer only)
1377 Dumps the raw stream to ./stream.dump.
1378 Useful when ripping from DVD or network.
1379 If you give more than one of \-dumpaudio, \-dumpvideo, \-dumpstream
1380 on the command line only the last one will work.
1383 .B \-dumpvideo (MPlayer only)
1384 Dump raw compressed video stream to ./stream.dump (not very usable).
1385 If you give more than one of \-dumpaudio, \-dumpvideo, \-dumpstream
1386 on the command line only the last one will work.
1389 .B \-dvbin <options> (DVB only)
1390 Pass the following parameters to the DVB input module, in order to override
1396 Specifies using card number 1\-4 (default: 1).
1397 .IPs file=<filename>
1398 Instructs MPlayer to read the channels list from <filename>.
1399 Default is ~/.mplayer/\:channels.conf.{sat,ter,cbl,atsc} (based on your card type)
1400 or ~/.mplayer/\:channels.conf as a last resort.
1401 .IPs timeout=<1\-30>
1402 Maximum number of seconds to wait when trying to tune a
1403 frequency before giving up (default: 30).
1408 .B \-dvd\-device <path to device> (DVD only)
1409 Specify the DVD device or .iso filename (default: /dev/\:dvd).
1410 You can also specify a directory that contains files previously copied directly
1411 from a DVD (with e.g.\& vobcopy).
1414 .B \-dvd\-speed <factor or speed in KB/s> (DVD only)
1415 Try to limit DVD speed (default: 0, no change).
1416 DVD base speed is about 1350KB/s, so a 8x drive can read at speeds up to
1418 Slower speeds make the drive more quiet, for watching DVDs 2700KB/s should be
1419 quiet and fast enough.
1420 MPlayer resets the speed to the drive default value on close.
1421 Values less than 100 mean multiples of 1350KB/s, i.e.\& \-dvd\-speed 8 selects
1425 You need write access to the DVD device to change the speed.
1428 .B \-dvdangle <angle ID> (DVD only)
1429 Some DVD discs contain scenes that can be viewed from multiple angles.
1430 Here you can tell MPlayer which angles to use (default: 1).
1434 Enables edit decision list (EDL) actions during playback.
1435 Video will be skipped over and audio will be muted and unmuted according to
1436 the entries in the given file.
1437 See http://www.mplayerhq.hu/\:DOCS/\:HTML/\:en/\:edl.html for details
1441 .B \-endpos <[[hh:]mm:]ss[.ms]|size[b|kb|mb]> (also see \-ss and \-sb)
1442 Stop at given time or byte position.
1445 Byte position is enabled only for MEncoder and will not be accurate, as it can
1446 only stop at a frame boundary.
1447 When used in conjunction with \-ss option, \-endpos time will shift forward by
1448 seconds specified with \-ss.
1455 .IPs "\-endpos 01:10:00"
1456 Stop at 1 hour 10 minutes.
1457 .IPs "\-ss 10 \-endpos 56"
1458 Stop at 1 minute 6 seconds.
1459 .IPs "\-endpos 100mb"
1466 Force index rebuilding.
1467 Useful for files with broken index (A/V desync, etc).
1468 This will enable seeking in files where seeking was not possible.
1469 You can fix the index permanently with MEncoder (see the documentation).
1472 This option only works if the underlying media supports seeking
1473 (i.e.\& not with stdin, pipe, etc).
1476 .B \-fps <float value>
1477 Override video framerate.
1478 Useful if the original value is wrong or missing.
1481 .B \-frames <number>
1482 Play/\:convert only first <number> frames, then quit.
1485 .B \-hr\-mp3\-seek (MP3 only)
1487 Enabled when playing from an external MP3 file, as we need to seek
1488 to the very exact position to keep A/V sync.
1489 Can be slow especially when seeking backwards since it has to rewind
1490 to the beginning to find an exact frame position.
1493 .B \-idx (also see \-forceidx)
1494 Rebuilds index of files if no index was found, allowing seeking.
1495 Useful with broken/\:incomplete downloads, or badly created files.
1498 This option only works if the underlying media supports seeking
1499 (i.e.\& not with stdin, pipe, etc).
1503 Skip rebuilding index file.
1504 MEncoder skips writing the index with this option.
1507 .B \-ipv4\-only\-proxy (network only)
1508 Skip the proxy for IPv6 addresses.
1509 It will still be used for IPv4 connections.
1512 .B \-loadidx <index file>
1513 The file from which to read the video index data saved by \-saveidx.
1514 This index will be used for seeking, overriding any index data
1515 contained in the AVI itself.
1516 MPlayer will not prevent you from loading an index file generated
1517 from a different AVI, but this is sure to cause unfavorable results.
1520 This option is obsolete now that MPlayer has OpenDML support.
1523 .B \-mc <seconds/frame>
1524 maximum A-V sync correction per frame (in seconds)
1527 .B \-mf <option1:option2:...>
1528 Used when decoding from multiple PNG or JPEG files.
1530 Available options are:
1535 input file width (default: autodetect)
1537 input file height (default: autodetect)
1539 output fps (default: 25)
1541 input file type (available: jpeg, png, tga, sgi)
1547 Force usage of non-interleaved AVI parser (fixes playback
1548 of some bad AVI files).
1551 .B \-nobps (AVI only)
1552 Do not use average byte/\:second value for A-V sync.
1553 Helps with some AVI files with broken header.
1557 Disables extension-based demuxer selection.
1558 By default, when the file type (demuxer) cannot be detected reliably
1559 (the file has no header or it is not reliable enough), the filename
1560 extension is used to select the demuxer.
1561 Always falls back on content-based demuxer selection.
1564 .B \-passwd <password> (also see \-user) (network only)
1565 Specify password for HTTP authentication.
1568 .B \-prefer\-ipv4 (network only)
1569 Use IPv4 on network connections.
1570 Falls back on IPv6 automatically.
1573 .B \-prefer\-ipv6 (IPv6 network only)
1574 Use IPv6 on network connections.
1575 Falls back on IPv4 automatically.
1578 .B \-psprobe <byte position>
1579 When playing an MPEG-PS or MPEG-PES streams, this option lets you specify
1580 how many bytes in the stream you want MPlayer to scan in order to identify
1581 the video codec used.
1582 This option is needed to play EVO or VDR files containing H.264 streams.
1585 .B \-pvr <option1:option2:...> (PVR only)
1586 This option tunes various encoding properties of the PVR capture module.
1587 It has to be used with any hardware MPEG encoder based card supported by the
1589 The Hauppauge WinTV PVR\-150/250/350/500 and all IVTV based
1590 cards are known as PVR capture cards.
1591 Be aware that only Linux 2.6.18 kernel
1592 and above is able to handle MPEG stream through V4L2 layer.
1593 For hardware capture of an MPEG stream and watching it with
1594 MPlayer/MEncoder, use 'pvr://' as a movie URL.
1596 Available options are:
1599 Specify input aspect ratio:
1609 .IPs arate=<32000\-48000>
1610 Specify encoding audio rate (default: 48000 Hz, available: 32000, 44100
1613 Specify MPEG audio layer encoding (default: 2).
1614 .IPs abitrate=<32\-448>
1615 Specify audio encoding bitrate in kbps (default: 384).
1617 Specify audio encoding mode.
1618 Available preset values are 'stereo', 'joint_stereo', 'dual' and 'mono' (default: stereo).
1619 .IPs vbitrate=<value>
1620 Specify average video bitrate encoding in Mbps (default: 6).
1622 Specify video encoding mode:
1624 vbr: Variable BitRate (default)
1626 cbr: Constant BitRate
1629 Specify peak video bitrate encoding in Mbps
1630 (only useful for VBR encoding, default: 9.6).
1632 Choose an MPEG format for encoding:
1634 ps: MPEG-2 Program Stream (default)
1636 ts: MPEG-2 Transport Stream
1638 mpeg1: MPEG-1 System Stream
1640 vcd: Video CD compatible stream
1642 svcd: Super Video CD compatible stream
1644 dvd: DVD compatible stream
1650 .B \-radio <option1:option2:...> (radio only)
1651 These options set various parameters of the radio capture module.
1652 For listening to radio with MPlayer use 'radio://<frequency>'
1653 (if channels option is not given) or 'radio://<channel_number>'
1654 (if channels option is given) as a movie URL.
1655 You can see allowed frequency range by running MPlayer with '\-v'.
1656 To start the grabbing subsystem, use 'radio://<frequency or channel>/capture'.
1657 If the capture keyword is not given you can listen to radio
1658 using the line-in cable only.
1659 Using capture to listen is not recommended due to synchronization
1660 problems, which makes this process uncomfortable.
1662 Available options are:
1665 Radio device to use (default: /dev/radio0 for Linux and /dev/tuner0 for *BSD).
1667 Radio driver to use (default: v4l2 if available, otherwise v4l).
1668 Currently, v4l and v4l2 drivers are supported.
1669 .IPs volume=<0..100>
1670 sound volume for radio device (default 100)
1671 .IPs "freq_min=<value> (*BSD BT848 only)"
1672 minimum allowed frequency (default: 87.50)
1673 .IPs "freq_max=<value> (*BSD BT848 only)"
1674 maximum allowed frequency (default: 108.00)
1675 .IPs channels=<frequency>\-<name>,<frequency>\-<name>,...
1677 Use _ for spaces in names (or play with quoting ;-).
1678 The channel names will then be written using OSD and the slave commands
1679 radio_step_channel and radio_set_channel will be usable for
1680 a remote control (see LIRC).
1681 If given, number in movie URL will be treated as channel position in
1685 radio://1, radio://104.4, radio_set_channel 1
1686 .IPs "adevice=<value> (radio capture only)"
1687 Name of device to capture sound from.
1688 Without such a name capture will be disabled,
1689 even if the capture keyword appears in the URL.
1690 For ALSA devices use it in the form hw=<card>.<device>.
1691 If the device name contains a '=', the module will use
1692 ALSA to capture, otherwise OSS.
1693 .IPs "arate=<value> (radio capture only)"
1694 Rate in samples per second (default: 44100).
1697 When using audio capture set also \-rawaudio rate=<value> option
1698 with the same value as arate.
1699 If you have problems with sound speed (runs too quickly), try to play
1700 with different rate values (e.g.\& 48000,44100,32000,...).
1701 .IPs "achannels=<value> (radio capture only)"
1702 Number of audio channels to capture.
1706 .B \-rawaudio <option1:option2:...>
1707 This option lets you play raw audio files.
1708 You have to use \-demuxer rawaudio as well.
1709 It may also be used to play audio CDs which are not 44kHz 16-bit stereo.
1710 For playing raw AC-3 streams use \-rawaudio format=0x2000 \-demuxer rawaudio.
1712 Available options are:
1716 .IPs channels=<value>
1719 rate in samples per second
1720 .IPs samplesize=<value>
1721 sample size in bytes
1722 .IPs bitrate=<value>
1723 bitrate for rawaudio files
1730 .B \-rawvideo <option1:option2:...>
1731 This option lets you play raw video files.
1732 You have to use \-demuxer rawvideo as well.
1734 Available options are:
1739 rate in frames per second (default: 25.0)
1740 .IPs sqcif|qcif|cif|4cif|pal|ntsc
1741 set standard image size
1743 image width in pixels
1745 image height in pixels
1746 .IPs i420|yv12|yuy2|y8
1749 colorspace (fourcc) in hex or string constant.
1750 Use \-rawvideo format=help for a list of possible strings.
1760 .IPs "mplayer foreman.qcif -demuxer rawvideo -rawvideo qcif"
1761 Play the famous "foreman" sample video.
1762 .IPs "mplayer sample-720x576.yuv -demuxer rawvideo -rawvideo w=720:h=576"
1763 Play a raw YUV sample.
1769 Used with 'rtsp://' URLs to force the client's port number.
1770 This option may be useful if you are behind a router and want to forward
1771 the RTSP stream from the server to a specific client.
1774 .B \-rtsp\-destination
1775 Used with 'rtsp://' URLs to force the destination IP address to be bound.
1776 This option may be useful with some RTSP server which do not
1777 send RTP packets to the right interface.
1778 If the connection to the RTSP server fails, use \-v to see
1779 which IP address MPlayer tries to bind to and try to force
1780 it to one assigned to your computer instead.
1783 .B \-rtsp\-stream\-over\-tcp (LIVE555 and NEMESI only)
1784 Used with 'rtsp://' URLs to specify that the resulting incoming RTP and RTCP
1785 packets be streamed over TCP (using the same TCP connection as RTSP).
1786 This option may be useful if you have a broken internet connection that does
1787 not pass incoming UDP packets (see http://www.live555.com/\:mplayer/).
1790 .B \-saveidx <filename>
1791 Force index rebuilding and dump the index to <filename>.
1792 Currently this only works with AVI files.
1795 This option is obsolete now that MPlayer has OpenDML support.
1798 .B \-sb <byte position> (also see \-ss)
1799 Seek to byte position.
1800 Useful for playback from CD-ROM images or VOB files with junk at the beginning.
1803 .B \-speed <0.01\-100>
1804 Slow down or speed up playback by the factor given as parameter.
1805 Not guaranteed to work correctly with \-oac copy.
1809 Selects the output sample rate to be used
1810 (of course sound cards have limits on this).
1811 If the sample frequency selected is different from that
1812 of the current media, the resample or lavcresample audio filter will be inserted
1813 into the audio filter layer to compensate for the difference.
1814 The type of resampling can be controlled by the \-af\-adv option.
1815 The default is fast resampling that may cause distortion.
1818 .B \-ss <time> (also see \-sb)
1819 Seek to given time position.
1825 Seeks to 56 seconds.
1826 .IPs "\-ss 01:10:00"
1827 Seeks to 1 hour 10 min.
1833 Tells MPlayer not to discard TS packets reported as broken in the stream.
1834 Sometimes needed to play corrupted MPEG-TS files.
1837 .B \-tsprobe <byte position>
1838 When playing an MPEG-TS stream, this option lets you specify how many
1839 bytes in the stream you want MPlayer to search for the desired
1840 audio and video IDs.
1843 .B \-tsprog <1\-65534>
1844 When playing an MPEG-TS stream, you can specify with this option which
1845 program (if present) you want to play.
1846 Can be used with \-vid and \-aid.
1849 .B \-tv <option1:option2:...> (TV/\:PVR only)
1850 This option tunes various properties of the TV capture module.
1851 For watching TV with MPlayer, use 'tv://' or 'tv://<channel_number>'
1852 or even 'tv://<channel_name> (see option channels for channel_name below)
1854 You can also use 'tv:///<input_id>' to start watching a
1855 movie from a composite or S-Video input (see option input for details).
1857 Available options are:
1861 .IPs "automute=<0\-255> (v4l and v4l2 only)"
1862 If signal strength reported by device is less than this value,
1863 audio and video will be muted.
1864 In most cases automute=100 will be enough.
1865 Default is 0 (automute disabled).
1867 See \-tv driver=help for a list of compiled-in TV input drivers.
1868 available: dummy, v4l, v4l2, bsdbt848 (default: autodetect)
1870 Specify TV device (default: /dev/\:video0).
1872 For the bsdbt848 driver you can provide both bktr and tuner device
1873 names separating them with a comma, tuner after
1874 bktr (e.g.\& -tv device=/dev/bktr1,/dev/tuner1).
1876 Specify input (default: 0 (TV), see console output for available inputs).
1878 Specify the frequency to set the tuner to (e.g.\& 511.250).
1879 Not compatible with the channels parameter.
1881 Specify the output format of the tuner with a preset value supported by the
1882 V4L driver (yv12, rgb32, rgb24, rgb16, rgb15, uyvy, yuy2, i420) or an
1883 arbitrary format given as hex value.
1884 Try outfmt=help for a list of all available formats.
1888 output window height
1890 framerate at which to capture video (frames per second)
1891 .IPs buffersize=<value>
1892 maximum size of the capture buffer in megabytes (default: dynamical)
1894 For bsdbt848 and v4l, PAL, SECAM, NTSC are available.
1895 For v4l2, see the console output for a list of all available norms,
1896 also see the normid option below.
1897 .IPs "normid=<value> (v4l2 only)"
1898 Sets the TV norm to the given numeric ID.
1899 The TV norm depends on the capture card.
1900 See the console output for a list of available TV norms.
1901 .IPs channel=<value>
1902 Set tuner to <value> channel.
1903 .IPs chanlist=<value>
1904 available: europe-east, europe-west, us-bcast, us-cable, etc
1905 .IPs channels=<chan>\-<name>[=<norm>],<chan>\-<name>[=<norm>],...
1906 Set names for channels.
1908 If <chan> is an integer greater than 1000, it will be treated as frequency (in kHz)
1909 rather than channel name from frequency table.
1911 Use _ for spaces in names (or play with quoting ;-).
1912 The channel names will then be written using OSD, and the slave commands
1913 tv_step_channel, tv_set_channel and tv_last_channel will be usable for
1914 a remote control (see LIRC).
1915 Not compatible with the frequency parameter.
1918 The channel number will then be the position in the 'channels' list,
1922 tv://1, tv://TV1, tv_set_channel 1, tv_set_channel TV1
1923 .IPs [brightness|contrast|hue|saturation]=<\-100\-100>
1924 Set the image equalizer on the card.
1925 .IPs audiorate=<value>
1926 Set audio capture bitrate.
1928 Capture audio even if there are no audio sources reported by v4l.
1932 Choose an audio mode:
1942 .IPs forcechan=<1\-2>
1943 By default, the count of recorded audio channels is determined automatically
1944 by querying the audio mode from the TV card.
1945 This option allows forcing stereo/\:mono recording regardless of the amode
1946 option and the values returned by v4l.
1947 This can be used for troubleshooting when the TV card is unable to report the
1949 .IPs adevice=<value>
1950 Set an audio device.
1951 <value> should be /dev/\:xxx for OSS and a hardware ID for ALSA.
1952 You must replace any ':' by a '.' in the hardware ID for ALSA.
1953 .IPs audioid=<value>
1954 Choose an audio output of the capture card, if it has more than one.
1955 .IPs "[volume|bass|treble|balance]=<0\-65535> (v4l1)"
1956 .IPs "[volume|bass|treble|balance]=<0\-100> (v4l2)"
1957 These options set parameters of the mixer on the video capture card.
1958 They will have no effect, if your card does not have one.
1959 For v4l2 50 maps to the default value of the
1960 control, as reported by the driver.
1961 .IPs "gain=<0\-100> (v4l2)"
1962 Set gain control for video devices (usually webcams) to the desired
1963 value and switch off automatic control.
1964 A value of 0 enables automatic control.
1965 If this option is omitted, gain control will not be modified.
1966 .IPs immediatemode=<bool>
1967 A value of 0 means capture and buffer audio and video together
1968 (default for MEncoder).
1969 A value of 1 (default for MPlayer) means to do video capture only and let the
1970 audio go through a loopback cable from the TV card to the sound card.
1972 Use hardware MJPEG compression (if the card supports it).
1973 When using this option, you do not need to specify the width and height
1974 of the output window, because MPlayer will determine it automatically
1975 from the decimation value (see below).
1976 .IPs decimation=<1|2|4>
1977 choose the size of the picture that will be compressed by hardware
1992 .IPs quality=<0\-100>
1993 Choose the quality of the JPEG compression
1994 (< 60 recommended for full size).

1997 .IPs tformat=<format>
1998 Specify TV teletext display format (default: 0):
2004 2: opaque with inverted colors
2006 3: transparent with inverted colors
2008 .IPs tpage=<100\-899>
2009 Specify initial TV teletext page number (default: 100).
2010 .IPs tlang=<\-1\-127>
2011 Specify default teletext language code (default: 0), which will be used
2012 as primary language until a type 28 packet is received.
2013 Useful when the teletext system uses a non-latin character set, but language
2014 codes are not transmitted via teletext type 28 packets for some reason.
2015 To see a list of supported language codes set this option to \-1.
2016 .IPs "hidden_video_renderer (dshow only)"
2017 Terminate stream with video renderer instead of Null renderer (default: off).
2018 Will help if video freezes but audio does not.
2020 May not work with \-vo directx and \-vf crop combination.
2021 .IPs "hidden_vp_renderer (dshow only)"
2022 Terminate VideoPort pin stream with video renderer
2023 instead of removing it from the graph (default: off).
2024 Useful if your card has a VideoPort pin and video is choppy.
2026 May not work with \-vo directx and \-vf crop combination.
2027 .IPs "system_clock (dshow only)"
2028 Use the system clock as sync source instead of the default graph clock
2029 (usually the clock from one of the live sources in graph).
2030 .IPs "normalize_audio_chunks (dshow only)"
2031 Create audio chunks with a time length equal to
2032 video frame time length (default: off).
2033 Some audio cards create audio chunks about 0.5s in size, resulting in
2034 choppy video when using immediatemode=0.
2038 .B \-tvscan <option1:option2:...> (TV and MPlayer only)
2039 Tune the TV channel scanner.
2040 MPlayer will also print value for "-tv channels=" option,
2041 including existing and just found channels.
2043 Available suboptions are:
2046 Begin channel scanning immediately after startup (default: disabled).
2047 .IPs period=<0.1\-2.0>
2048 Specify delay in seconds before switching to next channel (default: 0.5).
2049 Lower values will cause faster scanning, but can detect
2050 inactive TV channels as active.
2051 .IPs threshold=<1\-100>
2052 Threshold value for the signal strength (in percent), as reported
2053 by the device (default: 50).
2054 A signal strength higher than this value will indicate that the
2055 currently scanning channel is active.
2059 .B \-user <username> (also see \-passwd) (network only)
2060 Specify username for HTTP authentication.
2063 .B \-user\-agent <string>

3093 .B \-geometry x[%][:y[%]] or [WxH][+x+y]
3094 Adjust where the output is on the screen initially.
3095 The x and y specifications are in pixels measured from the top-left of the
3096 screen to the top-left of the image being displayed, however if a percentage
3097 sign is given after the argument it turns the value into a percentage of the
3098 screen size in that direction.
3099 It also supports the standard X11 \-geometry option format.
3100 If an external window is specified using the \-wid option, then the x and

3170 Double buffering fixes flicker by storing two frames in memory, and
3171 displaying one while decoding another.
3172 It can affect OSD negatively, but often removes OSD flickering.
3176 Do not grab the mouse pointer after a video mode change (\-vm).
3177 Useful for multihead setups.
3181 Do not keep window aspect ratio when resizing windows.
3182 Only works with the x11, xv, xmga, xvidix, directx video output drivers.

3201 and may crash or worse.
3202 Use at your own risk!
3205 .B \-panscanrange <\-19.0\-99.0> (experimental)
3206 Change the range of the pan-and-scan functionality (default: 1).
3207 Positive values mean multiples of the default range.
3208 Negative numbers mean you can zoom in up to a factor of \-panscanrange+1.
3209 E.g. \-panscanrange \-3 allows a zoom factor of up to 4.
3210 This feature is experimental.
3211 Do not report bugs unless you are using \-vo gl.
3214 .B \-refreshrate <Hz>
3215 Set the monitor refreshrate in Hz.
3216 Currently only supported by \-vo directx combined with the \-vm option.

3233 do not know the screen resolution like fbdev, x11 and TV-out.
3236 .B \-screenw <pixels>
3237 Specify the screen width for video output drivers which
3238 do not know the screen resolution like fbdev, x11 and TV-out.
3241 .B \-stop\-xscreensaver (X11 only)
3242 Turns off xscreensaver at startup and turns it on again on exit.
3243 If your screensaver supports neither the XSS nor XResetScreenSaver
3244 API please use \-heartbeat\-cmd instead.
3248 Try to change to a different video mode.
3249 Supported by the dga, x11, xv, sdl and directx video output drivers.
3250 If used with the directx video output driver the \-screenw,
3251 \-screenh, \-bpp and \-refreshrate options can be used to set
3252 the new display mode.
3256 Enables VBI for the vesa, dfbmga and svga video output drivers.
3259 .B \-wid <window ID> (also see \-guiwid) (X11, OpenGL and DirectX only)
3260 This tells MPlayer to attach to an existing window.
3261 Useful to embed MPlayer in a browser (e.g.\& the plugger extension).
3264 .B \-xineramascreen <\-2\-...>
3265 In Xinerama configurations (i.e.\& a single desktop that spans across multiple
3266 displays) this option tells MPlayer which screen to display the movie on.
3267 A value of \-2 means fullscreen across the whole virtual display (in this case
3268 Xinerama information is completely ignored), \-1 means
3269 fullscreen on the display the window currently is on.
3270 The initial position set via the \-geometry option is relative to the
3272 Will usually only work with "\-fstype \-fullscreen" or "\-fstype none".
3273 This option is not suitable to only set the startup screen (because
3274 it will always display on the given screen in fullscreen mode),
3275 \-geometry is the best that is available for that purpose
3277 Supported by the gl, gl2, x11, and xv video output drivers.
3280 .B \-zrbw (\-vo zr only)
3281 Display in black and white.

3469 Necessary for proper benchmarking of drivers that change
3470 image buffers on monitor retrace only (nVidia).
3471 Default is not to disable image display (nobenchmark).
3473 Very simple deinterlacer.
3474 Might not look better than \-vf tfields=1,
3475 but it is the only deinterlacer for xvmc (default: nobobdeint).
3477 Queue frames for display to allow more parallel work of the video hardware.
3478 May add a small (not noticeable) constant A/V desync (default: noqueue).
3480 Use sleep function while waiting for rendering to finish

3492 Considered obsolete.
3495 .B sdl (SDL only, buggy/outdated)
3496 Highly platform independent SDL (Simple Directmedia Layer) library
3497 video output driver.
3498 Since SDL uses its own X11 layer, MPlayer X11 options do not have
3500 Note that it has several minor bugs (\-vm/\-novm is mostly ignored,
3501 \-fs behaves like \-novm should, window is in top-left corner when
3502 returning from fullscreen, panscan is not supported, ...)
3505 .IPs driver=<driver>
3506 Explicitly choose the SDL driver to use.
3508 Use XVideo through the sdl video output driver (default: forcexv).

3579 packed YUV output format, with e.g.\& \-vf format=yuy2.
3582 .IPs device_id=<number>
3583 Choose the display device to use in fullscreen.
3584 .IPs fs_res=<width>:<height>
3585 Specify the fullscreen resolution (useful on slow systems).
3590 .B macosx (Mac OS X 10.4 or 10.3.9 with QuickTime 7)
3591 Mac OS X CoreVideo video output driver
3594 .IPs device_id=<number>
3595 Choose the display device to use for fullscreen or set it to \-1 to
3596 always use the same screen the video window is on (default: \-1 \- auto).
3598 Write output to a shared memory buffer instead of displaying it and
3599 try to open an existing NSConnection for communication with a GUI.
3600 .IPs buffer_name=<name>
3601 Name of the shared buffer created with shm_open as well as the name of
3602 the NSConnection MPlayer will try to open (default: "mplayerosx").
3603 Setting buffer_name implicitly enables shared_buffer.
3608 .B fbdev (Linux only)
3609 Uses the kernel framebuffer to play video.
3613 Explicitly choose the fbdev device name to use (e.g.\& /dev/\:fb0) or the
3614 name of the VIDIX subdevice if the device name starts with 'vidix'
3615 (e.g.\& 'vidixsis_vid' for the sis driver).
3620 .B fbdev2 (Linux only)
3621 Uses the kernel framebuffer to play video,
3622 alternative implementation.
3626 Explicitly choose the fbdev device name to use (default: /dev/\:fb0).
3632 Very general video output driver that should work on any VESA VBE 2.0

3643 Use the VIDIX driver.
3645 Activate the Linux Video Overlay on top of VESA mode.
3651 Play video using the SVGA library.
3655 Specify video mode to use.
3656 The mode can be given in a <width>x<height>x<colors> format,
3657 e.g.\& 640x480x16M or be a graphics mode number, e.g.\& 84.
3659 Draw OSD into black bands below the movie (slower).
3661 Use only native drawing functions.
3662 This avoids direct rendering, OSD and hardware acceleration.
3664 Force frame switch on vertical retrace.
3665 Usable only with \-double.
3666 It has the same effect as the \-vsync option.
3668 Try to select a video mode with square pixels.
3670 Use svga with VIDIX.
3676 OpenGL video output driver, simple version.
3677 Video size must be smaller than
3678 the maximum texture size of your OpenGL implementation.
3679 Intended to work even with the most basic OpenGL implementations,
3680 but also makes use of newer extensions, which allow support for more
3681 colorspaces and direct rendering.
3682 For optimal speed try something similar to
3684 \-vo gl:yuv=2:rectangle=2:force\-pbo:ati\-hack \-dr \-noslices
3686 The code performs very few checks, so if a feature does not work, this
3687 might be because it is not supported by your card/OpenGL implementation
3688 even if you do not get any error message.
3689 Use glxinfo or a similar tool to display the supported OpenGL extensions.
3693 ATI drivers may give a corrupted image when PBOs are used (when using \-dr
3695 This option fixes this, at the expense of using a bit more memory.
3697 Always uses PBOs to transfer textures even if this involves an extra copy.
3698 Currently this gives a little extra speed with NVidia drivers and a lot more
3699 speed with ATI drivers.
3700 May need \-noslices and the ati\-hack suboption to work correctly.
3702 Changes the way the OSD behaves when the size of the
3703 window changes (default: disabled).
3704 When enabled behaves more like the other video output drivers,
3705 which is better for fixed-size fonts.
3706 Disabled looks much better with FreeType fonts and uses the
3707 borders in fullscreen mode.
3708 Does not work correctly with ass subtitles (see \-ass), you can instead
3709 render them without OpenGL support via \-vf ass.
3710 .IPs osdcolor=<0xAARRGGBB>
3711 Color for OSD (default: 0x00ffffff, corresponds to non-transparent white).
3712 .IPs rectangle=<0,1,2>
3713 Select usage of rectangular textures which saves video RAM, but often is
3714 slower (default: 0).
3716 0: Use power-of-two textures (default).
3718 1: Use the GL_ARB_texture_rectangle extension.
3720 2: Use the GL_ARB_texture_non_power_of_two extension.
3721 In some cases only supported in software and thus very slow.
3723 .IPs swapinterval=<n>
3724 Minimum interval between two buffer swaps, counted in
3725 displayed frames (default: 1).
3726 1 is equivalent to enabling VSYNC, 0 to disabling VSYNC.
3727 Values below 0 will leave it at the system default.
3728 This limits the framerate to (horizontal refresh rate / n).
3729 Requires GLX_SGI_swap_control support to work.
3730 With some (most/all?) implementations this only works in fullscreen mode.
3732 Select the type of YUV to RGB conversion.
3734 0: Use software conversion (default).
3735 Compatible with all OpenGL versions.
3736 Provides brightness, contrast and saturation control.
3738 1: Use register combiners.
3739 This uses an nVidia-specific extension (GL_NV_register_combiners).
3740 At least three texture units are needed.
3741 Provides saturation and hue control.
3742 This method is fast but inexact.
3744 2: Use a fragment program.
3745 Needs the GL_ARB_fragment_program extension and at least three texture units.
3746 Provides brightness, contrast, saturation and hue control.
3748 3: Use a fragment program using the POW instruction.
3749 Needs the GL_ARB_fragment_program extension and at least three texture units.
3750 Provides brightness, contrast, saturation, hue and gamma control.
3751 Gamma can also be set independently for red, green and blue.
3752 Method 4 is usually faster.
3754 4: Use a fragment program with additional lookup.
3755 Needs the GL_ARB_fragment_program extension and at least four texture units.
3756 Provides brightness, contrast, saturation, hue and gamma control.
3757 Gamma can also be set independently for red, green and blue.
3759 5: Use ATI-specific method (for older cards).
3760 This uses an ATI-specific extension (GL_ATI_fragment_shader \- not
3761 GL_ARB_fragment_shader!).
3762 At least three texture units are needed.
3763 Provides saturation and hue control.
3764 This method is fast but inexact.
3766 6: Use a 3D texture to do conversion via lookup.
3767 Needs the GL_ARB_fragment_program extension and at least four texture units.
3768 Extremely slow (software emulation) on some (all?) ATI cards since it uses
3769 a texture with border pixels.
3770 Provides brightness, contrast, saturation, hue and gamma control.
3771 Gamma can also be set independently for red, green and blue.
3772 Speed depends more on GPU memory bandwidth than other methods.
3775 Use the GL_MESA_ycbcr_texture extension to convert YUV to RGB.
3776 In most cases this is probably slower than doing software conversion to RGB.
3778 Select the scaling function to use for luminance scaling.
3779 Only valid for yuv modes 2, 3, 4 and 6.
3781 0: Use simple linear filtering (default).
3783 1: Use bicubic B-spline filtering (better quality).
3784 Needs one additional texture unit.
3785 Older cards will not be able to handle this for chroma at least in fullscreen mode.
3787 2: Use cubic filtering in horizontal, linear filtering in vertical direction.
3788 Works on a few more cards than method 1.
3790 3: Same as 1 but does not use a lookup texture.
3791 Might be faster on some cards.
3793 4: Use experimental unsharp masking with 3x3 support and a default strength of 0.5 (see filter-strength).
3795 5: Use experimental unsharp masking with 5x5 support and a default strength of 0.5 (see filter-strength).
3798 Select the scaling function to use for chrominance scaling.
3799 For details see lscale.
3800 .IPs filter-strength=<value>
3801 Set the effect strength for the lscale/cscale filters that support it.
3802 .IPs customprog=<filename>
3803 Load a custom fragment program from <filename>.
3804 See TOOLS/edgedect.fp for an example.
3805 .IPs customtex=<filename>
3806 Load a custom "gamma ramp" texture from <filename>.
3807 This can be used in combination with yuv=4 or with the customprog option.
3809 If enabled (default) use GL_LINEAR interpolation, otherwise use GL_NEAREST
3810 for customtex texture.
3811 .IPs (no)customtrect
3812 If enabled, use texture_rectangle for customtex texture.
3813 Default is disabled.
3817 Normally there is no reason to use the following options, they mostly
3818 exist for testing purposes.
3823 Call glFinish() before swapping buffers.
3824 Slower but in some cases more correct output (default: disabled).
3826 Enables support for more (RGB and BGR) color formats (default: enabled).
3827 Needs OpenGL version >= 1.2.
3828 .IPs slice-height=<0\-...>
3829 Number of lines copied to texture in one piece (default: 0).
3833 If YUV colorspace is used (see yuv suboption), special rules apply:
3835 If the decoder uses slice rendering (see \-noslices), this setting
3836 has no effect, the size of the slices as provided by the decoder is used.
3838 If the decoder does not use slice rendering, the default is 16.
3841 Enable or disable support for OSD rendering via OpenGL (default: enabled).
3842 This option is for testing; to disable the OSD use \-osdlevel 0 instead.
3844 Enable or disable aspect scaling and pan-and-scan support (default: enabled).
3845 Disabling might increase speed.
3852 Variant of the OpenGL video output driver.
3853 Supports videos larger than the maximum texture size but lacks many of the
3854 advanced features and optimizations of the gl driver and is unlikely to be
3859 same as gl (default: enabled)
3861 Select the type of YUV to RGB conversion.
3862 If set to anything except 0 OSD will be disabled and brightness, contrast and
3863 gamma setting is only available via the global X server settings.
3864 Apart from this the values have the same meaning as for \-vo gl.
3869 Produces no video output.
3870 Useful for benchmarking.

3875 You can get a list and an explanation of available suboptions
3876 by executing 'mplayer \-vo aa:help'.
3879 The driver does not handle \-aspect correctly.
3882 You probably have to specify \-monitorpixelaspect.

3921 .IPs buffermode=single|double|triple
3922 Double and triple buffering give best results if you want to avoid tearing issues.
3923 Triple buffering is more efficient than double buffering as it does
3924 not block MPlayer while waiting for the vertical retrace.
3925 Single buffering should be avoided (default: single).
3926 .IPs fieldparity=top|bottom
3927 Control the output order for interlaced frames (default: disabled).
3928 Valid values are top = top fields first, bottom = bottom fields first.
3929 This option does not have any effect on progressive film material
3930 like most MPEG movies are.
3931 You need to enable this option if you have tearing issues or unsmooth
3932 motions watching interlaced film material.
3934 Will force layer with ID N for playback (default: \-1 \- auto).

3956 picture processing is done in hardware.
3957 Works only on the primary head.
3959 Make use of the Matrox sub picture layer to display the OSD (default: enabled).
3961 Turn on TV-out on the second head (default: enabled).
3962 The output quality is amazing as it is a full interlaced picture
3963 with proper sync to every odd/\:even field.
3964 .IPs tvnorm=pal|ntsc|auto
3965 Will set the TV norm of the Matrox card without the need
3966 for modifying /etc/\:directfbrc (default: disabled).
3967 Valid norms are pal = PAL, ntsc = NTSC.
3968 Special norm is auto (auto-adjust using PAL/\:NTSC) because it decides
3969 which norm to use by looking at the framerate of the movie.
3975 Matrox specific video output driver that makes use of the YUV back
3976 end scaler on Gxxx cards through a kernel module.
3977 If you have a Matrox card, this is the fastest option.

4272 Each file takes the frame number padded with leading zeros as name.
4273 24bpp RGB and BGR formats are supported.
4277 Specifies the compression level.
4278 0 is no compression, 9 is maximum compression.
4279 .IPs alpha (default: noalpha)
4280 Create PNG files with an alpha channel.
4281 Note that MPlayer in general does not support alpha, so this will only
4282 be useful in some rare cases.
4288 Output each frame into a Targa file in the current directory.
4289 Each file takes the frame number padded with leading zeros as name.
4290 The purpose of this video output driver is to have a simple lossless
4291 image writer to use without any external library.
4292 It supports the BGR[A] color format, with 15, 24 and 32 bpp.

4525 1: careful (Should work with broken encoders.)
4527 2: normal (default) (Works with compliant encoders.)
4529 3: aggressive (More checks, but might cause problems even for valid bitstreams.)
4533 .IPs "fast (MPEG-2, MPEG-4, and H.264 only)"
4534 Enable optimizations which do not comply to the specification and might
4535 potentially cause problems, like simpler dequantization, simpler motion
4536 compensation, assuming use of the default quantization matrix, assuming
4537 YUV 4:2:0 and skipping a few checks to detect damaged bitstreams.
4539 grayscale only decoding (a bit faster than with color)
4540 .IPs "idct=<0\-99> (see \-lavcopts)"
4541 For best decoding quality use the same IDCT algorithm for decoding and encoding.
4542 This may come at a price in accuracy, though.
4543 .IPs lowres=<number>[,<w>]
4544 Decode at lower resolutions.
4545 Low resolution decoding is not supported by all codecs, and it will
4546 often result in ugly artifacts.
4547 This is not a bug, but a side effect of not decoding at full resolution.
4559 If <w> is specified lowres decoding will be used only if the width of the
4560 video is major than or equal to <w>.
4562 .B o=<key>=<value>[,<key>=<value>[,...]]
4563 Pass AVOptions to libavcodec decoder.
4564 Note, a patch to make the o= unneeded and pass all unknown options through
4565 the AVOption system is welcome.
4566 A full list of AVOptions can be found in the FFmpeg manual.
4567 Note that some options may conflict with MEncoder options.
4577 .IPs "sb=<number> (MPEG-2 only)"
4578 Skip the given number of macroblock rows at the bottom.
4579 .IPs "st=<number> (MPEG-2 only)"
4580 Skip the given number of macroblock rows at the top.
4581 .IPs "skiploopfilter=<skipvalue> (H.264 only)"
4582 Skips the loop filter (AKA deblocking) during H.264 decoding.
4583 Since the filtered frame is supposed to be used as reference
4584 for decoding dependent frames this has a worse effect on quality
4585 than not doing deblocking on e.g.\& MPEG-2 video.
4586 But at least for high bitrate HDTV this provides a big speedup with
4587 no visible quality loss.
4589 <skipvalue> can be either one of the following:
4594 default: Skip useless processing steps (e.g.\& 0 size packets in AVI).
4596 nonref: Skip frames that are not referenced (i.e.\& not used for
4597 decoding other frames, the error cannot "build up").
4599 bidir: Skip B-Frames.
4601 nonkey: Skip all frames except keyframes.
4603 all: Skip all frames.
4605 .IPs "skipidct=<skipvalue> (MPEG-1/2 only)"
4606 Skips the IDCT step.
4607 This degrades quality a lot of in almost all cases
4608 (see skiploopfilter for available skip values).
4609 .IPs skipframe=<skipvalue>
4610 Skips decoding of frames completely.
4611 Big speedup, but jerky motion and sometimes bad artifacts
4612 (see skiploopfilter for available skip values).
4613 .IPs "threads=<1\-8> (MPEG-1/2 and H.264 only)"
4614 number of threads to use for decoding (default: 1)
4616 Visualize motion vectors.

4623 2: Visualize forward predicted MVs of B-frames.
4625 4: Visualize backward predicted MVs of B-frames.
4628 Prints some statistics and stores them in ./vstats_*.log.
4633 Disable drawing video by 16-pixel height slices/\:bands, instead draws the
4634 whole frame in a single run.
4635 May be faster or slower, depending on video card and available cache.
4636 It has effect only with libmpeg2 and libavcodec codecs.
4640 Do not play/\:encode sound.
4641 Useful for benchmarking.
4645 Do not play/\:encode video.
4646 In many cases this will not work, use \-vc null \-vo null instead.
4649 .B \-pp <quality> (also see \-vf pp)
4650 Set the DLL postprocess level.
4651 This option is no longer usable with \-vf pp.
4652 It only works with Win32 DirectShow DLLs with internal postprocessing routines.
4653 The valid range of \-pp values varies by codec, it is mostly
4654 0\-6, where 0=disable, 6=slowest/\:best.
4657 .B \-pphelp (also see \-vf pp)

4702 .B \-sws <software scaler type> (also see \-vf scale and \-zoom)
4703 Specify the software scaler algorithm to be used with the \-zoom option.
4704 This affects video output drivers which lack hardware acceleration, e.g.\& x11.
4706 Available types are:
4715 bicubic (good quality) (default)
4719 nearest neighbor (bad quality)
4723 luma bicubic / chroma bilinear
4731 natural bicubic spline
4737 Some \-sws options are tunable.

4745 Use a '\-' before the codec name to omit it.
4746 Use a '+' before the codec name to force it, this will likely crash!
4747 If the list has a trailing ',' MPlayer will fall back on codecs not

4788 Disables aspect calculations.
4791 .B \-xvidopts <option1:option2:...>
4792 Specify additional parameters when decoding with Xvid.
4795 Since libavcodec is faster than Xvid you might want to use the libavcodec
4796 postprocessing filter (\-vf pp) and decoder (\-vfm ffmpeg) instead.

4827 .B \-xy <value> (also see \-zoom)
4831 Scale image by factor <value>.
4833 Set width to value and calculate height to keep correct aspect ratio.
4838 .B \-y <y> (also see \-zoom) (MPlayer only)
4839 Scale image to height <y> (if software/\:hardware scaling is available).
4840 Disables aspect calculations.
4844 Allow software scaling, where available.
4845 This will allow scaling with output drivers (like x11, fbdev) that
4846 do not support hardware scaling where MPlayer disables scaling by
4847 default for performance reasons.
4852 Audio filters allow you to modify the audio stream and its properties.
4856 .B \-af <filter1[=parameter1:parameter2:...],filter2,...>
4857 Setup a chain of audio filters.
4860 To get a full list of available audio filters, see \-af help.
4862 Audio filters are managed in lists.
4863 There are a few commands to manage the filter list.
4866 .B \-af\-add <filter1[,filter2,...]>
4867 Appends the filters given as arguments to the filter list.
4870 .B \-af\-pre <filter1[,filter2,...]>
4871 Prepends the filters given as arguments to the filter list.
4874 .B \-af\-del <index1[,index2,...]>
4875 Deletes the filters at the given indexes.
4876 Index numbers start at 0, negative numbers address the end of the
4877 list (\-1 is the last).
4881 Completely empties the filter list.
4883 Available filters are:
4886 .B resample[=srate[:sloppy[:type]]]
4887 Changes the sample rate of the audio stream.
4888 Can be used if you have a fixed frequency sound card or if you are
4889 stuck with an old sound card that is only capable of max 44.1kHz.
4890 This filter is automatically enabled if necessary.
4891 It only supports 16-bit integer and float in native-endian format as input.
4894 With MEncoder, you need to also use \-srate <srate>.
4898 output sample frequency in Hz.
4899 The valid range for this parameter is 8000 to 192000.
4900 If the input and output sample frequency are the same or if this
4901 parameter is omitted the filter is automatically unloaded.
4902 A high sample frequency normally improves the audio quality,
4903 especially when used in combination with other filters.
4905 Allow (1) or disallow (0) the output frequency to differ slightly
4906 from the frequency given by <srate> (default: 1).
4907 Can be used if the startup of the playback is extremely slow.
4909 Selects which resampling method to use.
4911 0: linear interpolation (fast, poor quality especially when upsampling)
4913 1: polyphase filterbank and integer processing
4915 2: polyphase filterbank and floating point processing (slow, best quality)
4925 .IPs "mplayer \-af resample=44100:0:0"
4926 would set the output frequency of the resample filter to 44100Hz using
4927 exact output frequency scaling and linear interpolation.
4932 .B lavcresample[=srate[:length[:linear[:count[:cutoff]]]]]
4933 Changes the sample rate of the audio stream to an integer <srate> in Hz.
4934 It only supports the 16-bit native-endian format.
4937 With MEncoder, you need to also use \-srate <srate>.
4941 the output sample rate
4943 length of the filter with respect to the lower sampling rate (default: 16)
4945 if 1 then filters will be linearly interpolated between polyphase entries
4947 log2 of the number of polyphase entries
4948 (..., 10->1024, 11->2048, 12->4096, ...)
4951 cutoff frequency (0.0\-1.0), default set depending upon filter length
4956 .B lavcac3enc[=tospdif[:bitrate[:minchn]]]
4957 Encode multi-channel audio to AC-3 at runtime using libavcodec.
4958 Supports 16-bit native-endian input format, maximum 6 channels.
4959 The output is big-endian when outputting a raw AC-3 stream,
4960 native-endian when outputting to S/PDIF.
4961 The output sample rate of this filter is same with the input sample rate.
4962 When input sample rate is 48kHz, 44.1kHz, or 32kHz, this filter directly use it.
4963 Otherwise a resampling filter is auto-inserted before this filter to make
4964 the input and output sample rate be 48kHz.
4965 You need to specify '\-channels N' to make the decoder decode audio into
4966 N-channel, then the filter can encode the N-channel input to AC-3.
4971 Output raw AC-3 stream if zero or not set,
4972 output to S/PDIF for passthrough when <tospdif> is set non-zero.
4974 The bitrate to encode the AC-3 stream.
4975 Set it to either 384 or 384000 to get 384kbits.
4976 Valid values: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256,
4977 320, 384, 448, 512, 576, 640
4978 Default bitrate is based on the input channel number:
4979 1ch: 96, 2ch: 192, 3ch: 224, 4ch: 384, 5ch: 448, 6ch: 448
4981 If the input channel number is less than <minchn>, the filter will
4982 detach itself (default: 5).
4988 Produces a sine sweep.
4992 Sine function delta, use very low values to hear the sweep.
4997 .B sinesuppress[=freq:decay]
4998 Remove a sine at the specified frequency.
4999 Useful to get rid of the 50/60Hz noise on low quality audio equipment.
5000 It probably only works on mono input.
5004 The frequency of the sine which should be removed (in Hz) (default: 50)
5006 Controls the adaptivity (a larger value will make the filter adapt to
5007 amplitude and phase changes quicker, a smaller value will make the
5008 adaptation slower) (default: 0.0001).
5009 Reasonable values are around 0.001.

5028 .B equalizer=[g1:g2:g3:...:g10]
5029 10 octave band graphic equalizer, implemented using 10 IIR band pass filters.
5030 This means that it works regardless of what type of audio is being played back.
5031 The center frequencies for the 10 bands are:
5035 .IPs "No. frequency"
5050 If the sample rate of the sound being played is lower than the center
5051 frequency for a frequency band, then that band will be disabled.
5052 A known bug with this filter is that the characteristics for the
5053 uppermost band are not completely symmetric if the sample
5054 rate is close to the center frequency of that band.
5055 This problem can be worked around by upsampling the sound
5056 using the resample filter before it reaches this filter.

5071 while canceling it almost completely around 1kHz.
5076 .B channels=nch[:nr:from1:to1:from2:to2:from3:to3:...]
5077 Can be used for adding, removing, routing and copying audio channels.
5078 If only <nch> is given the default routing is used, it works as
5079 follows: If the number of output channels is bigger than the number of
5080 input channels empty channels are inserted (except mixing from mono to
5081 stereo, then the mono channel is repeated in both of the output
5083 If the number of output channels is smaller than the number
5084 of input channels the exceeding channels are truncated.
5088 number of output channels (1\-6)
5090 number of routes (1\-6)
5091 .IPs <from1:to1:from2:to2:from3:to3:...>

5099 .IPs "mplayer \-af channels=4:4:0:1:1:0:2:2:3:3 media.avi"
5100 Would change the number of channels to 4 and set up 4 routes that
5101 swap channel 0 and channel 1 and leave channel 2 and 3 intact.
5102 Observe that if media containing two channels was played back, channels
5103 2 and 3 would contain silence but 0 and 1 would still be swapped.
5104 .IPs "mplayer \-af channels=6:4:0:0:0:1:0:2:0:3 media.avi"
5105 Would change the number of channels to 6 and set up 4 routes
5106 that copy channel 0 to channels 0 to 3.
5107 Channel 4 and 5 will contain silence.
5112 .B format[=format] (also see \-format)
5113 Convert between different sample formats.
5114 Automatically enabled when needed by the sound card or another filter.
5118 Sets the desired format.
5119 The general form is 'sbe', where 's' denotes the sign (either 's' for signed
5120 or 'u' for unsigned), 'b' denotes the number of bits per sample (16, 24 or 32)
5121 and 'e' denotes the endianness ('le' means little-endian, 'be' big-endian
5122 and 'ne' the endianness of the computer MPlayer is running on).
5123 Valid values (amongst others) are: 's16le', 'u32be' and 'u24ne'.
5124 Exceptions to this rule that are also valid format specifiers: u8, s8,
5125 floatle, floatbe, floatne, mulaw, alaw, mpeg2, ac3 and imaadpcm.
5131 Implements software volume control.
5132 Use this filter with caution since it can reduce the signal
5133 to noise ratio of the sound.
5134 In most cases it is best to set the level for the PCM sound to max,
5135 leave this filter out and control the output level to your
5136 speakers with the master volume control of the mixer.
5137 In case your sound card has a digital PCM mixer instead of an analog
5138 one, and you hear distortion, use the MASTER mixer instead.
5139 If there is an external amplifier connected to the computer (this
5140 is almost always the case), the noise level can be minimized by
5141 adjusting the master level and the volume knob on the amplifier
5142 until the hissing noise in the background is gone.
5144 This filter has a second feature: It measures the overall maximum
5145 sound level and prints out that level when MPlayer exits.
5146 This volume estimate can be used for setting the sound level in
5147 MEncoder such that the maximum dynamic range is utilized.
5150 This filter is not reentrant and can therefore only be enabled
5151 once for every audio stream.
5155 Sets the desired gain in dB for all channels in the stream
5156 from \-200dB to +60dB, where \-200dB mutes the sound
5157 completely and +60dB equals a gain of 1000 (default: 0).
5159 Turns soft clipping on (1) or off (0).
5160 Soft-clipping can make the sound more smooth if very
5161 high volume levels are used.
5162 Enable this option if the dynamic range of the
5163 loudspeakers is very low.
5166 This feature creates distortion and should be considered a last resort.
5173 .IPs "mplayer \-af volume=10.1:0 media.avi"
5174 Would amplify the sound by 10.1dB and hard-clip if the
5175 sound level is too high.
5180 .B pan=n[:L00:L01:L02:...L10:L11:L12:...Ln0:Ln1:Ln2:...]
5181 Mixes channels arbitrarily.
5182 Basically a combination of the volume and the channels filter
5183 that can be used to down-mix many channels to only a few,
5184 e.g.\& stereo to mono or vary the "width" of the center
5185 speaker in a surround sound system.
5186 This filter is hard to use, and will require some tinkering
5187 before the desired result is obtained.
5188 The number of options for this filter depends on
5189 the number of output channels.
5190 An example how to downmix a six-channel file to two channels with
5191 this filter can be found in the examples section near the end.
5195 number of output channels (1\-6)
5197 How much of input channel i is mixed into output channel j (0\-1).
5198 So in principle you first have n numbers saying what to do with the
5199 first input channel, then n numbers that act on the second input channel
5201 If you do not specify any numbers for some input channels, 0 is assumed.
5208 .IPs "mplayer \-af pan=1:0.5:0.5 media.avi"
5209 Would down-mix from stereo to mono.
5210 .IPs "mplayer \-af pan=3:1:0:0.5:0:1:0.5 media.avi"
5211 Would give 3 channel output leaving channels 0 and 1 intact,
5212 and mix channels 0 and 1 into output channel 2 (which could
5213 be sent to a subwoofer for example).
5219 Adds a subwoofer channel to the audio stream.
5220 The audio data used for creating the subwoofer channel is
5221 an average of the sound in channel 0 and channel 1.
5222 The resulting sound is then low-pass filtered by a 4th order
5223 Butterworth filter with a default cutoff frequency of 60Hz
5224 and added to a separate channel in the audio stream.
5227 Disable this filter when you are playing DVDs with Dolby
5228 Digital 5.1 sound, otherwise this filter will disrupt
5229 the sound to the subwoofer.
5233 cutoff frequency in Hz for the low-pass filter (20Hz to 300Hz) (default: 60Hz)
5234 For the best result try setting the cutoff frequency as low as possible.
5235 This will improve the stereo or surround sound experience.
5237 Determines the channel number in which to insert the sub-channel audio.
5238 Channel number can be between 0 and 5 (default: 5).
5239 Observe that the number of channels will automatically
5240 be increased to <ch> if necessary.
5247 .IPs "mplayer \-af sub=100:4 \-channels 5 media.avi"
5248 Would add a sub-woofer channel with a cutoff frequency of
5249 100Hz to output channel 4.
5255 Creates a center channel from the front channels.
5256 May currently be low quality as it does not implement a
5257 high-pass filter for proper extraction yet, but averages and
5258 halves the channels instead.
5262 Determines the channel number in which to insert the center channel.
5263 Channel number can be between 0 and 5 (default: 5).
5264 Observe that the number of channels will automatically
5265 be increased to <ch> if necessary.
5271 Decoder for matrix encoded surround sound like Dolby Surround.
5272 Many files with 2 channel audio actually contain matrixed surround sound.
5273 Requires a sound card supporting at least 4 channels.
5277 delay time in ms for the rear speakers (0 to 1000) (default: 20)
5278 This delay should be set as follows: If d1 is the distance
5279 from the listening position to the front speakers and d2 is the distance
5280 from the listening position to the rear speakers, then the delay should
5281 be set to 15ms if d1 <= d2 and to 15 + 5*(d1-d2) if d1 > d2.
5288 .IPs "mplayer \-af surround=15 \-channels 4 media.avi"
5289 Would add surround sound decoding with 15ms delay for the sound to the
5295 .B delay[=ch1:ch2:...]
5296 Delays the sound to the loudspeakers such that the sound from the
5297 different channels arrives at the listening position simultaneously.
5298 It is only useful if you have more than 2 loudspeakers.
5302 The delay in ms that should be imposed on each channel
5303 (floating point number between 0 and 1000).
5308 To calculate the required delay for the different channels do as follows:
5310 Measure the distance to the loudspeakers in meters in relation
5311 to your listening position, giving you the distances s1 to s5
5313 There is no point in compensating for the subwoofer (you will not hear the
5316 Subtract the distances s1 to s5 from the maximum distance,
5317 i.e.\& s[i] = max(s) \- s[i]; i = 1...5.
5319 Calculate the required delays in ms as d[i] = 1000*s[i]/342; i = 1...5.
5327 .IPs "mplayer \-af delay=10.5:10.5:0:0:7:0 media.avi"
5328 Would delay front left and right by 10.5ms, the two rear channels
5329 and the sub by 0ms and the center channel by 7ms.
5334 .B export[=mmapped_file[:nsamples]]
5335 Exports the incoming signal to other processes using memory mapping (mmap()).
5336 Memory mapped areas contain a header:
5339 int nch /*number of channels*/
5340 int size /*buffer size*/
5341 unsigned long long counter /*Used to keep sync, updated every
5342 time new data is exported.*/
5345 The rest is payload (non-interleaved) 16 bit data.
5349 file to map data to (default: ~/.mplayer/\:mplayer-af_export)
5351 number of samples per channel (default: 512)
5358 .IPs "mplayer \-af export=/tmp/mplayer-af_export:1024 media.avi"
5359 Would export 1024 samples per channel to '/tmp/mplayer-af_export'.
5364 .B extrastereo[=mul]
5365 (Linearly) increases the difference between left and right channels
5366 which adds some sort of "live" effect to playback.
5370 Sets the difference coefficient (default: 2.5).
5371 0.0 means mono sound (average of both channels), with 1.0 sound will be
5372 unchanged, with \-1.0 left and right channels will be swapped.
5377 .B volnorm[=method:target]
5378 Maximizes the volume without distorting the sound.
5382 Sets the used method.
5384 1: Use a single sample to smooth the variations via the standard
5385 weighted mean over past samples (default).
5387 2: Use several samples to smooth the variations via the standard
5388 weighted mean over past samples.
5391 Sets the target amplitude as a fraction of the maximum for the
5392 sample type (default: 0.25).
5397 .B ladspa=file:label[:controls...]
5398 Load a LADSPA (Linux Audio Developer's Simple Plugin API) plugin.
5399 This filter is reentrant, so multiple LADSPA plugins can be used at once.
5403 Specifies the LADSPA plugin library file.
5404 If LADSPA_PATH is set, it searches for the specified file.
5405 If it is not set, you must supply a fully specified pathname.
5407 Specifies the filter within the library.
5408 Some libraries contain only one filter, but others contain many of them.
5409 Entering 'help' here, will list all available filters within the specified
5410 library, which eliminates the use of 'listplugins' from the LADSPA SDK.
5412 Controls are zero or more floating point values that determine the
5413 behavior of the loaded plugin (for example delay, threshold or gain).
5414 In verbose mode (add \-v to the MPlayer command line), all available controls
5415 and their valid ranges are printed.
5416 This eliminates the use of 'analyseplugin' from the LADSPA SDK.
5422 Compressor/expander filter usable for microphone input.
5423 Prevents artifacts on very loud sound and raises the volume on
5425 This filter is untested, maybe even unusable.
5429 Noise gate filter similar to the comp audio filter.
5430 This filter is untested, maybe even unusable.
5434 Simple voice removal filter exploiting the fact that voice is
5435 usually recorded with mono gear and later 'center' mixed onto
5436 the final audio stream.
5437 Beware that this filter will turn your signal into mono.
5438 Works well for 2 channel tracks; do not bother trying it
5439 on anything but 2 channel stereo.
5442 .B scaletempo[=option1:option2:...]
5443 Scales audio tempo without altering pitch, optionally synced to playback
5446 This works by playing \'stride\' ms of audio at normal speed then
5447 consuming \'stride*scale\' ms of input audio.
5448 It pieces the strides together by blending \'overlap\'% of stride with
5449 audio following the previous stride.
5450 It optionally performs a short statistical analysis on the next \'search\'
5451 ms of audio to determine the best overlap position.
5455 Nominal amount to scale tempo.
5456 Scales this amount in addition to speed.
5458 .IPs stride=<amount>
5459 Length in milliseconds to output each stride.
5460 Too high of value will cause noticable skips at high scale amounts and
5461 an echo at low scale amounts.
5462 Very low values will alter pitch.
5463 Increasing improves performance.
5465 .IPs overlap=<percent>
5466 Percentage of stride to overlap.
5467 Decreasing improves performance.
5469 .IPs search=<amount>
5470 Length in milliseconds to search for best overlap position.

5475 Set response to speed change.
5478 Scale tempo in sync with speed (default).
5480 Reverses effect of filter.

5482 Add \'[ speed_mult 0.9438743126816935\' and \'] speed_mult 1.059463094352953\'
5483 to your input.conf to step by musical semi-tones.
5485 Loses sync with video.
5487 Scale both tempo and pitch.
5489 Ignore speed changes.
5497 .IPs "mplayer \-af scaletempo \-speed 1.2 media.ogg"
5498 Would playback media at 1.2x normal speed, with audio at normal pitch.
5499 Changing playback speed, would change audio tempo to match.
5500 .IPs "mplayer \-af scaletempo=scale=1.2:speed=none \-speed 1.2 media.ogg"
5501 Would playback media at 1.2x normal speed, with audio at normal pitch,
5502 but changing playback speed has no effect on audio tempo.
5503 .IPs "mplayer \-af scaletempo=stride=30:overlap=.50:search=10 media.ogg"
5504 Would tweak the quality and performace parameters.
5505 .IPs "mplayer \-af format=floatne,scaletempo media.ogg"

5509 Would playback audio file at 1.2x normal speed, with audio at normal pitch.
5510 Changing playback speed, would change pitch, leaving audio tempo at 1.2x.
5516 Collects and prints statistics about the audio stream, especially the volume.
5517 These statistics are especially intended to help adjusting the volume while
5519 The volumes are printed in dB and compatible with the volume audio filter.
5524 Video filters allow you to modify the video stream and its properties.
5528 .B \-vf <filter1[=parameter1:parameter2:...],filter2,...>

6050 shifts and averages the results.
6055 Force quantization parameter (default: 0, use QP from video).

6068 Ultra simple & slow postprocessing filter that compresses and
6069 decompresses the image at several (or \- in the case of quality
6070 level 8 \- all) shifts and averages the results.
6071 The way this differs from the behavior of spp is that uspp actually

6129 There are a couple of constants that can be used in the equation:
6135 X / Y: the coordinates of the current sample
6137 W / H: width and height of the image
6139 SW / SH: width/height scale depending on the currently filtered plane, e.g.\&
6140 1,1 and 0.5,0.5 for YUV 4:2:0.

6180 Only useful together with expand and scale.
6183 Control aspect ratio, calculate as DVB_HEIGHT*ASPECTRATIO (default:

6220 .B denoise3d[=luma_spatial:chroma_spatial:luma_tmp:chroma_tmp]

6242 .B ow[=depth[:luma_strength[:chroma_strength]]]

6257 .B eq[=brightness:contrast] (OBSOLETE)
6258 Software equalizer with interactive controls just like the hardware
6259 equalizer, for cards/\:drivers that do not support brightness and
6260 contrast controls in hardware.
6261 Might also be useful with MEncoder, either for fixing poorly captured
6262 movies, or for slightly reducing contrast to mask artifacts and get by
6263 with lower bitrates.
6274 .B eq2[=gamma:contrast:brightness:saturation:rg:gg:bg:weight]
6275 Alternative software equalizer that uses lookup tables (very slow),
6276 allowing gamma correction in addition to simple brightness
6277 and contrast adjustment.
6278 Note that it uses the same MMX optimized code as \-vf eq if all
6279 gamma values are 1.0.
6280 The parameters are given as floating point values.
6284 initial gamma value (default: 1.0)
6286 initial contrast, where negative values result in a
6287 negative image (default: 1.0)
6289 initial brightness (default: 0.0)
6291 initial saturation (default: 1.0)
6293 gamma value for the red component (default: 1.0)
6295 gamma value for the green component (default: 1.0)
6297 gamma value for the blue component (default: 1.0)
6299 The weight parameter can be used to reduce the effect of a high gamma value on
6300 bright image areas, e.g.\& keep them from getting overamplified and just plain
6302 A value of 0.0 turns the gamma correction all the way down while 1.0 leaves it
6303 at its full strength (default: 1.0).
6308 .B hue[=hue:saturation]
6309 Software equalizer with interactive controls just like the hardware
6310 equalizer, for cards/\:drivers that do not support hue and
6311 saturation controls in hardware.
6315 initial hue (default: 0.0)
6317 initial saturation, where negative values result
6318 in a negative chroma (default: 1.0)
6324 Convert planar YUV 4:2:0 to half-height packed 4:2:2, downsampling luma but
6325 keeping all chroma samples.
6326 Useful for output to low-resolution display devices when hardware downscaling
6327 is poor quality or is not available.
6328 Can also be used as a primitive luma-only deinterlacer with very low CPU
6333 By default, halfpack averages pairs of lines when downsampling.
6334 Any value different from 0 or 1 gives the default (averaging) behavior.
6336 0: Only use even lines when downsampling.
6338 1: Only use odd lines when downsampling.
6345 When interlaced video is stored in YUV 4:2:0 formats, chroma
6346 interlacing does not line up properly due to vertical downsampling of
6347 the chroma channels.
6348 This filter packs the planar 4:2:0 data into YUY2 (4:2:2) format with
6349 the chroma lines in their proper locations, so that in any given
6350 scanline, the luma and chroma data both come from the same field.
6354 Select the sampling mode.
6356 0: nearest-neighbor sampling, fast but incorrect
6358 1: linear interpolation (default)
6365 Only useful with MEncoder.
6366 If harddup is used when encoding, it will force duplicate frames to be
6367 encoded in the output.
6368 This uses slightly more space, but is necessary for output to MPEG
6369 files or if you plan to demux and remux the video stream after
6371 Should be placed at or near the end of the filter chain unless you
6372 have a good reason to do otherwise.
6376 Only useful with MEncoder.
6377 Softskip moves the frame skipping (dropping) step of encoding from
6378 before the filter chain to some point during the filter chain.
6379 This allows filters which need to see all frames (inverse telecine,
6380 temporal denoising, etc.) to function properly.
6381 Should be placed after the filters which need to see all frames and
6382 before any subsequent filters that are CPU-intensive.
6385 .B decimate[=max:hi:lo:frac]
6386 Drops frames that do not differ greatly from the previous frame in
6387 order to reduce framerate.
6388 The main use of this filter is for very-low-bitrate encoding (e.g.\&
6389 streaming over dialup modem), but it could in theory be used for
6390 fixing movies that were inverse-telecined incorrectly.
6394 Sets the maximum number of consecutive frames which can be
6395 dropped (if positive), or the minimum interval between
6396 dropped frames (if negative).
6397 .IPs <hi>,<lo>,<frac>
6398 A frame is a candidate for dropping if no 8x8 region differs by more
6399 than a threshold of <hi>, and if not more than <frac> portion (1
6400 meaning the whole image) differs by more than a threshold of <lo>.
6401 Values of <hi> and <lo> are for 8x8 pixel blocks and represent actual
6402 pixel value differences, so a threshold of 64 corresponds to 1 unit of
6403 difference for each pixel, or the same spread out differently over the
6409 .B dint[=sense:level]
6410 The drop-deinterlace (dint) filter detects and drops the first from a set
6411 of interlaced video frames.
6415 relative difference between neighboring pixels (default: 0.1)
6417 What part of the image has to be detected as interlaced to
6418 drop the frame (default: 0.15).
6423 .B lavcdeint (OBSOLETE)
6424 FFmpeg deinterlacing filter, same as \-vf pp=fd
6427 .B kerndeint[=thresh[:map[:order[:sharp[:twoway]]]]]
6428 Donald Graft's adaptive kernel deinterlacer.
6429 Deinterlaces parts of a video if a configurable threshold is exceeded.
6433 threshold (default: 10)
6436 0: Ignore pixels exceeding the threshold (default).
6438 1: Paint pixels exceeding the threshold white.
6442 0: Leave fields alone (default).
6448 0: Disable additional sharpening (default).
6450 1: Enable additional sharpening.
6454 0: Disable twoway sharpening (default).
6456 1: Enable twoway sharpening.
6462 .B unsharp[=l|cWxH:amount[:l|cWxH:amount]]
6463 unsharp mask / gaussian blur
6466 Apply effect on luma component.
6468 Apply effect on chroma components.
6469 .IPs <width>x<height>
6470 width and height of the matrix, odd sized in both directions
6471 (min = 3x3, max = 13x11 or 11x13, usually something between 3x3 and 7x7)
6473 Relative amount of sharpness/\:blur to add to the image
6474 (a sane range should be \-1.5\-1.5).
6487 .B il[=d|i][s][:[d|i][s]]
6488 (De)interleaves lines.
6489 The goal of this filter is to add the ability to process interlaced images
6490 pre-field without deinterlacing them.
6491 You can filter your interlaced DVD and play it on a TV without breaking the
6493 While deinterlacing (with the postprocessing filter) removes interlacing
6494 permanently (by smoothing, averaging, etc) deinterleaving splits the frame into
6495 2 fields (so called half pictures), so you can process (filter) them
6496 independently and then re-interleave them.
6500 deinterleave (placing one above the other)
6504 swap fields (exchange even & odd lines)
6510 (De)interleaves lines.
6511 This filter is very similar to the il filter but much faster, the main
6512 disadvantage is that it does not always work.
6513 Especially if combined with other filters it may produce randomly messed
6514 up images, so be happy if it works but do not complain if it does not for
6515 your combination of filters.
6519 Deinterleave fields, placing them side by side.
6521 Interleave fields again (reversing the effect of fil=d).
6527 Extracts a single field from an interlaced image using stride arithmetic
6528 to avoid wasting CPU time.
6529 The optional argument n specifies whether to extract the even or the odd
6530 field (depending on whether n is even or odd).
6533 .B detc[=var1=value1:var2=value2:...]
6534 Attempts to reverse the 'telecine' process to recover a clean,
6535 non-interlaced stream at film framerate.
6536 This was the first and most primitive inverse telecine filter to be
6537 added to MPlayer/\:MEncoder.
6538 It works by latching onto the telecine 3:2 pattern and following it as
6540 This makes it suitable for perfectly-telecined material, even in the
6541 presence of a fair degree of noise, but it will fail in the presence
6542 of complex post-telecine edits.
6543 Development on this filter is no longer taking place, as ivtc, pullup,
6544 and filmdint are better for most applications.
6545 The following arguments (see syntax above) may be used to control
6549 Set the frame dropping mode.
6551 0: Do not drop frames to maintain fixed output framerate (default).
6553 1: Always drop a frame when there have been no drops or telecine
6554 merges in the past 5 frames.
6556 2: Always maintain exact 5:4 input to output frame ratio.
6559 Use mode 1 or 2 with MEncoder.
6564 0: Fixed pattern with initial frame number specified by <fr>.
6566 1: aggressive search for telecine pattern (default)
6569 Set initial frame number in sequence.
6570 0\-2 are the three clean progressive frames; 3 and 4 are the two
6572 The default, \-1, means 'not in telecine sequence'.
6573 The number specified here is the type for the imaginary previous
6574 frame before the movie starts.
6575 .IPs "<t0>, <t1>, <t2>, <t3>"
6576 Threshold values to be used in certain modes.
6581 Experimental 'stateless' inverse telecine filter.
6582 Rather than trying to lock on to a pattern like the detc filter does,
6583 ivtc makes its decisions independently for each frame.
6584 This will give much better results for material that has undergone
6585 heavy editing after telecine was applied, but as a result it is not as
6586 forgiving of noisy input, for example TV capture.
6587 The optional parameter (ivtc=1) corresponds to the dr=1 option for the
6588 detc filter, and should be used with MEncoder but not with MPlayer.
6589 As with detc, you must specify the correct output framerate (\-ofps
6590 24000/1001) when using MEncoder.
6591 Further development on ivtc has stopped, as the pullup and filmdint
6592 filters appear to be much more accurate.
6595 .B pullup[=jl:jr:jt:jb:sb:mp]
6596 Third-generation pulldown reversal (inverse telecine) filter,
6597 capable of handling mixed hard-telecine, 24000/1001 fps progressive, and 30000/1001
6598 fps progressive content.
6599 The pullup filter is designed to be much more robust than detc or
6600 ivtc, by taking advantage of future context in making its decisions.
6601 Like ivtc, pullup is stateless in the sense that it does not lock onto
6602 a pattern to follow, but it instead looks forward to the following
6603 fields in order to identify matches and rebuild progressive frames.
6604 It is still under development, but believed to be quite accurate.
6606 .IPs "jl, jr, jt, and jb"
6607 These options set the amount of "junk" to ignore at
6608 the left, right, top, and bottom of the image, respectively.
6609 Left/\:right are in units of 8 pixels, while top/\:bottom are in units of
6611 The default is 8 pixels on each side.
6613 .IPs "sb (strict breaks)"
6614 Setting this option to 1 will reduce the chances of
6615 pullup generating an occasional mismatched frame, but it may also
6616 cause an excessive number of frames to be dropped during high motion
6618 Conversely, setting it to \-1 will make pullup match fields more
6620 This may help processing of video where there is slight blurring
6621 between the fields, but may also cause there to be interlaced frames
6624 .IPs "mp (metric plane)"
6625 This option may be set to 1 or 2 to use a chroma
6626 plane instead of the luma plane for doing pullup's computations.
6627 This may improve accuracy on very clean source material, but more
6628 likely will decrease accuracy, especially if there is chroma noise
6629 (rainbow effect) or any grayscale video.
6630 The main purpose of setting mp to a chroma plane is to reduce CPU load
6631 and make pullup usable in realtime on slow machines.
6636 Always follow pullup with the softskip filter when encoding to ensure
6637 that pullup is able to see each frame.
6638 Failure to do so will lead to incorrect output and will usually crash,
6639 due to design limitations in the codec/\:filter layer.
6643 .B filmdint[=options]
6644 Inverse telecine filter, similar to the pullup filter above.
6645 It is designed to handle any pulldown pattern, including mixed soft and
6646 hard telecine and limited support for movies that are slowed down or sped
6647 up from their original framerate for TV.
6648 Only the luma plane is used to find the frame breaks.
6649 If a field has no match, it is deinterlaced with simple linear
6651 If the source is MPEG-2, this must be the first filter to allow
6652 access to the field-flags set by the MPEG-2 decoder.
6653 Depending on the source MPEG, you may be fine ignoring this advice, as
6654 long as you do not see lots of "Bottom-first field" warnings.
6655 With no options it does normal inverse telecine, and should be used
6656 together with mencoder \-fps 30000/1001 \-ofps 24000/1001.
6657 When this filter is used with MPlayer, it will result in an uneven
6658 framerate during playback, but it is still generally better than using
6659 pp=lb or no deinterlacing at all.
6660 Multiple options can be specified separated by /.
6662 .IPs crop=<w>:<h>:<x>:<y>
6663 Just like the crop filter, but faster, and works on mixed hard and soft
6664 telecined content as well as when y is not a multiple of 4.
6665 If x or y would require cropping fractional pixels from the chroma
6666 planes, the crop area is extended.
6667 This usually means that x and y must be even.
6668 .IPs io=<ifps>:<ofps>
6669 For each ifps input frames the filter will output ofps frames.
6670 The ratio of ifps/\:ofps should match the \-fps/\-ofps ratio.
6671 This could be used to filter movies that are broadcast on TV at a frame
6672 rate different from their original framerate.
6674 If n is nonzero, the chroma plane is copied unchanged.
6675 This is useful for YV12 sampled TV, which discards one of the chroma
6678 On x86, if n=1, use MMX2 optimized functions, if n=2, use 3DNow!
6679 optimized functions, otherwise, use plain C.
6680 If this option is not specified, MMX2 and 3DNow! are auto-detected, use
6681 this option to override auto-detection.
6683 The larger n will speed up the filter at the expense of accuracy.
6684 The default value is n=3.
6685 If n is odd, a frame immediately following a frame marked with the
6686 REPEAT_FIRST_FIELD MPEG flag is assumed to be progressive, thus filter
6687 will not spend any time on soft-telecined MPEG-2 content.
6688 This is the only effect of this flag if MMX2 or 3DNow! is available.
6689 Without MMX2 and 3DNow, if n=0 or 1, the same calculations will be used
6691 If n=2 or 3, the number of luma levels used to find the frame breaks is
6692 reduced from 256 to 128, which results in a faster filter without losing
6694 If n=4 or 5, a faster, but much less accurate metric will be used to
6695 find the frame breaks, which is more likely to misdetect high vertical
6696 detail as interlaced content.
6698 If n is nonzero, print the detailed metrics for each frame.
6699 Useful for debugging.
6701 Deinterlace threshold.
6702 Used during de-interlacing of unmatched frames.
6703 Larger value means less deinterlacing, use n=256 to completely turn off
6707 Threshold for comparing a top and bottom fields.
6710 Threshold to detect temporal change of a field.
6713 Sum of Absolute Difference threshold, default is 64.
6718 This filter works only correct with MEncoder and acts on the MPEG-2 flags
6719 used for soft 3:2 pulldown (soft telecine).
6720 If you want to use the ivtc or detc filter on movies that are partly soft
6721 telecined, inserting this filter before them should make them more reliable.
6725 Inverse telecine for deinterlaced video.
6726 If 3:2-pulldown telecined video has lost one of the fields or is deinterlaced
6727 using a method that keeps one field and interpolates the other, the result is
6728 a juddering video that has every fourth frame duplicated.
6729 This filter is intended to find and drop those duplicates and restore the
6730 original film framerate.
6731 When using this filter, you must specify \-ofps that is 4/5 of
6732 the fps of the input file and place the softskip later in the
6733 filter chain to make sure that divtc sees all the frames.
6734 Two different modes are available:
6735 One pass mode is the default and is straightforward to use,
6736 but has the disadvantage that any changes in the telecine
6737 phase (lost frames or bad edits) cause momentary judder
6738 until the filter can resync again.
6739 Two pass mode avoids this by analyzing the whole video
6740 beforehand so it will have forward knowledge about the
6741 phase changes and can resync at the exact spot.
6744 correspond to pass one and two of the encoding process.
6745 You must run an extra pass using divtc pass one before the
6746 actual encoding throwing the resulting video away.
6747 Use \-nosound \-ovc raw \-o /dev/null to avoid
6748 wasting CPU power for this pass.
6749 You may add something like crop=2:2:0:0 after divtc
6750 to speed things up even more.
6751 Then use divtc pass two for the actual encoding.
6752 If you use multiple encoder passes, use divtc
6753 pass two for all of them.
6758 .IPs file=<filename>
6759 Set the two pass log filename (default: "framediff.log").
6760 .IPs threshold=<value>
6761 Set the minimum strength the telecine pattern must have for the filter to
6762 believe in it (default: 0.5).
6763 This is used to avoid recognizing false pattern from the parts of the video
6764 that are very dark or very still.
6765 .IPs window=<numframes>
6766 Set the number of past frames to look at when searching for pattern
6768 Longer window improves the reliability of the pattern search, but shorter
6769 window improves the reaction time to the changes in the telecine phase.
6770 This only affects the one pass mode.
6771 The two pass mode currently uses fixed window that extends to both future
6773 .IPs phase=0|1|2|3|4
6774 Sets the initial telecine phase for one pass mode (default: 0).
6775 The two pass mode can see the future, so it is able to use the correct
6776 phase from the beginning, but one pass mode can only guess.
6777 It catches the correct phase when it finds it, but this option can be used
6778 to fix the possible juddering at the beginning.
6779 The first pass of the two pass mode also uses this, so if you save the output
6780 from the first pass, you get constant phase result.
6781 .IPs deghost=<value>
6782 Set the deghosting threshold (0\-255 for one pass mode, \-255\-255 for two pass
6784 If nonzero, deghosting mode is used.
6785 This is for video that has been deinterlaced by blending the fields
6786 together instead of dropping one of the fields.
6787 Deghosting amplifies any compression artifacts in the blended frames, so the
6788 parameter value is used as a threshold to exclude those pixels from
6789 deghosting that differ from the previous frame less than specified value.
6790 If two pass mode is used, then negative value can be used to make the
6791 filter analyze the whole video in the beginning of pass-2 to determine
6792 whether it needs deghosting or not and then select either zero or the
6793 absolute value of the parameter.
6794 Specify this option for pass-2, it makes no difference on pass-1.
6798 .B phase[=t|b|p|a|u|T|B|A|U][:v]
6799 Delay interlaced video by one field time so that the field order
6801 The intended use is to fix PAL movies that have been captured with the
6802 opposite field order to the film-to-video transfer.
6806 Capture field order top-first, transfer bottom-first.
6807 Filter will delay the bottom field.
6809 Capture bottom-first, transfer top-first.
6810 Filter will delay the top field.
6812 Capture and transfer with the same field order.
6813 This mode only exists for the documentation of the other options to refer to,
6814 but if you actually select it, the filter will faithfully do nothing ;-)
6816 Capture field order determined automatically by field flags, transfer opposite.
6817 Filter selects among t and b modes on a frame by frame basis using field flags.
6818 If no field information is available, then this works just like u.
6820 Capture unknown or varying, transfer opposite.
6821 Filter selects among t and b on a frame by frame basis by analyzing the
6822 images and selecting the alternative that produces best match between the
6825 Capture top-first, transfer unknown or varying.
6826 Filter selects among t and p using image analysis.
6828 Capture bottom-first, transfer unknown or varying.
6829 Filter selects among b and p using image analysis.
6831 Capture determined by field flags, transfer unknown or varying.
6832 Filter selects among t, b and p using field flags and image analysis.
6833 If no field information is available, then this works just like U.
6834 This is the default mode.
6836 Both capture and transfer unknown or varying.
6837 Filter selects among t, b and p using image analysis only.
6840 Prints the selected mode for each frame and the average squared difference
6841 between fields for t, b, and p alternatives.
6846 Apply 3:2 'telecine' process to increase framerate by 20%.
6847 This most likely will not work correctly with MPlayer, but it can
6848 be used with 'mencoder \-fps 30000/1001 \-ofps 30000/1001 \-vf telecine'.
6849 Both fps options are essential!
6850 (A/V sync will break if they are wrong.)
6851 The optional start parameter tells the filter where in the telecine
6852 pattern to start (0\-3).
6855 .B tinterlace[=mode]
6856 Temporal field interlacing \- merge pairs of frames into an interlaced
6857 frame, halving the framerate.
6858 Even frames are moved into the upper field, odd frames to the lower field.
6859 This can be used to fully reverse the effect of the tfields filter (in mode 0).
6860 Available modes are:
6864 Move odd frames into the upper field, even into the lower field, generating
6865 a full-height frame at half framerate.
6867 Only output odd frames, even frames are dropped; height unchanged.
6869 Only output even frames, odd frames are dropped; height unchanged.
6871 Expand each frame to full height, but pad alternate lines with black;
6872 framerate unchanged.
6874 Interleave even lines from even frames with odd lines from odd frames.
6875 Height unchanged at half framerate.
6880 .B tfields[=mode[:field_dominance]]
6881 Temporal field separation \- split fields into frames, doubling the
6883 Like the telecine filter, tfields will only work properly with
6884 MEncoder, and only if both \-fps and \-ofps are set to the
6885 desired (double) framerate!
6889 0: Leave fields unchanged (will jump/\:flicker).
6891 1: Interpolate missing lines. (The algorithm used might not be so good.)
6893 2: Translate fields by 1/4 pixel with linear interpolation (no jump).
6895 4: Translate fields by 1/4 pixel with 4tap filter (higher quality) (default).
6896 .IPs <field_dominance>\ (DEPRECATED)
6898 Only works if the decoder exports the appropriate information and
6899 no other filters which discard that information come before tfields
6900 in the filter chain, otherwise it falls back to 0 (top field first).
6904 1: bottom field first
6907 This option will possibly be removed in a future version.
6908 Use \-field\-dominance instead.
6913 .B yadif=[mode[:field_dominance]]
6914 Yet another deinterlacing filter
6918 0: Output 1 frame for each frame.
6920 1: Output 1 frame for each field.
6922 2: Like 0 but skips spatial interlacing check.
6924 3: Like 1 but skips spatial interlacing check.
6925 .IPs <field_dominance>\ (DEPRECATED)
6926 Operates like tfields.
6929 This option will possibly be removed in a future version.
6930 Use \-field\-dominance instead.
6935 .B mcdeint=[mode[:parity[:qp]]]
6936 Motion compensating deinterlacer.
6937 It needs one field per frame as input and must thus be used together
6938 with tfields=1 or yadif=1/3 or equivalent.
6946 2: slow, iterative motion estimation
6948 3: extra slow, like 2 plus multiple reference frames
6950 0 or 1 selects which field to use (note: no autodetection yet!).
6952 Higher values should result in a smoother motion vector
6953 field but less optimal individual vectors.
6958 .B boxblur=radius:power[:radius:power]
6963 blur filter strength

7018 .B down3dright[=lines]
7019 Reposition and resize stereoscopic images.
7020 Extracts both stereo fields and places them side by side, resizing
7021 them to maintain the original movie aspect.
7025 number of lines to select from the middle of the image (default: 12)
7030 .B bmovl=hidden:opaque:fifo
7031 The bitmap overlay filter reads bitmaps from a FIFO and displays them
7032 on top of the movie, allowing some transformations on the image.
7033 Also see TOOLS/bmovl-test.c for a small bmovl test program.
7037 Set the default value of the 'hidden' flag (0=visible, 1=hidden).

7084 If you set this to \-255 you can then send a sequence of ALPHA-commands to set
7085 the area to \-225, \-200, \-175 etc for a nice fade-in-effect! ;)
7089 255: Make everything opaque.
7091 \-255: Make everything transparent.
7094 Clear the framebuffer before blitting.
7096 0: The image will just be blitted on top of the old one, so you do not need to
7097 send 1.8MB of RGBA32 data every time a small part of the screen is updated.
7105 .B framestep=I|[i]step
7106 Renders only every nth frame or every intra frame (keyframe).
7108 If you call the filter with I (uppercase) as the parameter, then
7110 keyframes are rendered.
7111 For DVDs it generally means one in every 15/12 frames (IBBPBBPBBPBBPBB),
7112 for AVI it means every scene change or every keyint value (see \-lavcopts
7113 keyint= value if you use MEncoder to encode the video).
7115 When a keyframe is found, an 'I!' string followed by a newline character is
7116 printed, leaving the current line of MPlayer/\:MEncoder output on the screen,
7117 because it contains the time (in seconds) and frame number of the keyframe
7118 (You can use this information to split the AVI.).
7120 If you call the filter with a numeric parameter 'step' then only one in
7121 every 'step' frames is rendered.
7123 If you put an 'i' (lowercase) before the number then an 'I!' is printed
7124 (like the I parameter).
7126 If you give only the i then nothing is done to the frames, only I! is
7130 .B tile=xtiles:ytiles:output:start:delta
7131 Tile a series of images into a single, bigger image.
7132 If you omit a parameter or use a value less than 0, then the default
7134 You can also stop when you are satisfied (... \-vf tile=10:5 ...).
7135 It is probably a good idea to put the scale filter before the tile :-)
7142 number of tiles on the x axis (default: 5)
7144 number of tiles on the y axis (default: 5)
7146 Render the tile when 'output' number of frames are reached, where 'output'
7147 should be a number less than xtile * ytile.
7148 Missing tiles are left blank.
7149 You could, for example, write an 8 * 7 tile every 50 frames to have one
7150 image every 2 seconds @ 25 fps.
7152 outer border thickness in pixels (default: 2)
7154 inner border thickness in pixels (default: 4)
7159 .B delogo[=x:y:w:h:t]
7160 Suppresses a TV station logo by a simple interpolation of the
7162 Just set a rectangle covering the logo and watch it disappear (and
7163 sometimes something even uglier appear \- your mileage may vary).
7167 top left corner of the logo

7171 Thickness of the fuzzy edge of the rectangle (added to w and h).
7172 When set to \-1, a green rectangle is drawn on the screen to
7173 simplify finding the right x,y,w,h parameters.
7178 .B remove\-logo=/path/to/logo_bitmap_file_name.pgm
7179 Suppresses a TV station logo, using a PGM or PPM image
7180 file to determine which pixels comprise the logo.
7181 The width and height of the image file must match
7182 those of the video stream being processed.
7183 Uses the filter image and a circular blur
7184 algorithm to remove the logo.
7186 .IPs /path/to/logo_bitmap_file_name.pgm
7187 [path] + filename of the filter image.
7191 .B zrmjpeg[=options]
7192 Software YV12 to MJPEG encoder for use with the zr2 video
7195 .IPs maxheight=<h>|maxwidth=<w>
7196 These options set the maximum width and height the zr card
7197 can handle (the MPlayer filter layer currently cannot query those).
7198 .IPs {dc10+,dc10,buz,lml33}-{PAL|NTSC}
7199 Use these options to set maxwidth and maxheight automatically to the
7200 values known for card/\:mode combo.
7201 For example, valid options are: dc10-PAL and buz-NTSC (default: dc10+PAL)
7203 Select color or black and white encoding.
7204 Black and white encoding is faster.
7205 Color is the default.
7207 Horizontal decimation 1, 2 or 4.
7209 Vertical decimation 1, 2 or 4.
7211 Set JPEG compression quality [BEST] 1 \- 20 [VERY BAD].
7213 By default, decimation is only performed if the Zoran hardware
7214 can upscale the resulting MJPEG images to the original size.
7215 The option fd instructs the filter to always perform the requested
7221 Allows acquiring screenshots of the movie using slave mode
7222 commands that can be bound to keypresses.
7223 See the slave mode documentation and the INTERACTIVE CONTROL
7224 section for details.
7225 Files named 'shotNNNN.png' will be saved in the working directory,
7226 using the first available number \- no files will be overwritten.
7227 The filter has no overhead when not used and accepts an arbitrary
7228 colorspace, so it is safe to add it to the configuration file.
7233 Moves SSA/ASS subtitle rendering to an arbitrary point in the filter chain.
7234 Only useful with the \-ass option.
7239 .IPs "\-vf ass,screenshot"
7240 Moves SSA/ASS rendering before the screenshot filter.
7241 Screenshots taken this way will contain subtitles.
7246 .B blackframe[=amount:threshold]
7247 Detect frames that are (almost) completely black.
7248 Can be useful to detect chapter transitions or commercials.
7249 Output lines consist of the frame number of the detected frame, the
7250 percentage of blackness, the frame type and the frame number of the last
7251 encountered keyframe.
7254 Percentage of the pixels that have to be below the threshold (default: 98).
7256 Threshold below which a pixel value is considered black (default: 32).
7261 .SH "GENERAL ENCODING OPTIONS (MENCODER ONLY)"
7264 .B \-audio\-delay <any floating-point number>
7265 Delays either audio or video by setting a delay field in the header
7267 This does not delay either stream while encoding, but the player will
7268 see the delay field and compensate accordingly.
7269 Positive values delay the audio, and negative values delay the video.
7270 Note that this is the exact opposite of the \-delay option.
7271 For example, if a video plays correctly with \-delay 0.2, you can
7272 fix the video with MEncoder by using \-audio\-delay \-0.2.
7274 Currently, this option only works with the default muxer (\-of avi).
7275 If you are using a different muxer, then you must use \-delay instead.
7278 .B \-audio\-density <1\-50>
7279 Number of audio chunks per second (default is 2 for 0.5s long audio chunks).
7282 CBR only, VBR ignores this as it puts each packet in a new chunk.
7285 .B \-audio\-preload <0.0\-2.0>
7286 Sets up the audio buffering time interval (default: 0.5s).
7289 .B \-fafmttag <format>
7290 Can be used to override the audio format tag of the output file.
7295 .IPs "\-fafmttag 0x55"
7296 Will have the output file contain 0x55 (mp3) as audio format tag.
7301 .B \-ffourcc <fourcc>
7302 Can be used to override the video fourcc of the output file.
7307 .IPs "\-ffourcc div3"
7308 Will have the output file contain 'div3' as video fourcc.
7313 .B \-force\-avi\-aspect <0.2\-3.0>
7314 Override the aspect stored in the AVI OpenDML vprp header.
7315 This can be used to change the aspect ratio with '\-ovc copy'.
7318 .B \-frameno\-file <filename> (DEPRECATED)
7319 Specify the name of the audio file with framenumber mappings created in
7320 the first (audio only) pass of a special three pass encoding mode.
7323 Using this mode will most likely give you A-V desync.
7325 It is kept for backwards compatibility only and will possibly
7326 be removed in a future version.
7330 Use a more precise, but much slower method for skipping areas.
7331 Areas marked for skipping are not seeked over, instead all
7332 frames are decoded, but only the necessary frames are encoded.
7333 This allows starting at non-keyframe boundaries.
7336 Not guaranteed to work right with '\-ovc copy'.

7878 Not recommended (much larger file, little quality difference and weird side
7879 effects: msmpeg4, h263 will be very low quality, ratecontrol will be confused
7880 resulting in lower quality and some decoders will not be able to decode it).
7882 Recommended for normal mpeg4/\:mpeg1video encoding (default).
7884 Recommended for h263(p)/\:msmpeg4.
7885 The reason for preferring 3 over 2 is that 2 could lead to overflows.
7886 (This will be fixed for h263(p) by changing the quantizer per MB in
7887 the future, msmpeg4 cannot be fixed as it does not support that.)
7891 .B lmin=<0.01\-255.0>
7892 Minimum frame-level Lagrange multiplier for ratecontrol (default: 2.0).
7893 Lavc will rarely use quantizers below the value of lmin.
7894 Lowering lmin will make lavc more likely to choose lower quantizers for
7895 some frames, but not lower than the value of vqmin.
7896 Likewise, raising lmin will make lavc less likely to choose low
7897 quantizers, even if vqmin would have allowed them.
7898 You probably want to set lmin approximately equal to vqmin.
7899 When adaptive quantization is in use, changing lmin/lmax may have less
7900 of an effect; see mblmin/mblmax.
7904 .B lmax=<0.01\-255.0>

7918 Maximum macroblock-level Lagrange multiplier for ratecontrol
7924 Constant quantizer /\: constant quality encoding (selects fixed quantizer mode).
7925 A lower value means better quality but larger files (default: \-1).
7926 In case of snow codec, value 0 means lossless encoding.
7927 Since the other codecs do not support this, vqscale=0 will have an undefined
7929 1 is not recommended (see vqmin for details).

7967 none (very low quality)
7969 full (slow, currently unmaintained and disabled)

7973 phods (low quality, currently unmaintained and disabled)
7975 EPZS: size=1 diamond, size can be adjusted with the *dia options
7978 X1 (experimental, currently aliased to EPZS)
7980 iter (iterative overlapped block, only used in snow)
7987 0\-3 currently ignores the amount of bits spent,
7988 so quality may be low.
7992 .B me_range=<0\-9999>
7993 motion estimation search range (default: 0 (unlimited))
7996 .B mbd=<0\-2> (also see *cmp, qpel)
7997 Macroblock decision algorithm (high quality mode), encode each macro
7998 block in all modes and choose the best.
7999 This is slow but results in better quality and file size.
8000 When mbd is set to 1 or 2, the value of mbcmp is ignored when comparing
8001 macroblocks (the mbcmp value is still used in other places though, in particular
8002 the motion search algorithms).
8003 If any comparison setting (precmp, subcmp, cmp, or mbcmp) is nonzero,
8004 however, a slower but better half-pel motion search will be used,
8005 regardless of what mbd is set to.
8006 If qpel is set, quarter-pel motion search will be used regardless.
8010 Use comparison function given by mbcmp (default).
8012 Select the MB mode which needs the fewest bits (=vhq).
8014 Select the MB mode which has the best rate distortion.
8020 Same as mbd=1, kept for compatibility reasons.
8024 Allow 4 motion vectors per macroblock (slightly better quality).
8025 Works better if used with mbd>0.
8029 overlapped block motion compensation (H.263+)
8033 loop filter (H.263+)
8034 note, this is broken
8037 .B inter_threshold <\-1000\-1000>
8038 Does absolutely nothing at the moment.
8042 maximum interval between keyframes in frames (default: 250 or one
8043 keyframe every ten seconds in a 25fps movie.
8044 This is the recommended default for MPEG-4).
8045 Most codecs require regular keyframes in order to limit the accumulation of mismatch error.
8046 Keyframes are also needed for seeking, as seeking is only possible to a keyframe \- but
8047 keyframes need more space than other frames, so larger numbers here mean
8048 slightly smaller files but less precise seeking.
8049 0 is equivalent to 1, which makes every frame a keyframe.
8050 Values >300 are not recommended as the quality might be bad depending upon
8051 decoder, encoder and luck.
8052 It is common for MPEG-1/2 to use values <=30.
8055 .B sc_threshold=<\-1000000000\-1000000000>
8056 Threshold for scene change detection.
8057 A keyframe is inserted by libavcodec when it detects a scene change.
8058 You can specify the sensitivity of the detection with this option.
8059 \-1000000000 means there is a scene change detected at every frame,
8060 1000000000 means no scene changes are detected (default: 0).
8063 .B sc_factor=<any positive integer>
8064 Causes frames with higher quantizers to be more likely to trigger a
8065 scene change detection and make libavcodec use an I-frame (default: 1).
8066 1\-16 is a sane range.
8067 Values between 2 and 6 may yield increasing PSNR (up to approximately
8068 0.04 dB) and better placement of I-frames in high-motion scenes.
8069 Higher values than 6 may give very slightly better PSNR (approximately
8070 0.01 dB more than sc_factor=6), but noticably worse visual quality.
8073 .B vb_strategy=<0\-2> (pass one only)
8074 strategy to choose between I/P/B-frames:
8078 Always use the maximum number of B-frames (default).
8080 Avoid B-frames in high motion scenes.
8081 See the b_sensitivity option to tune this strategy.
8083 Places B-frames more or less optimally to yield maximum quality (slower).
8084 You may want to reduce the speed impact of this option by tuning the
8090 .B b_sensitivity=<any integer greater than 0>
8091 Adjusts how sensitively vb_strategy=1 detects motion and avoids using
8092 B-frames (default: 40).
8093 Lower sensitivities will result in more B-frames.
8094 Using more B-frames usually improves PSNR, but too many B-frames can
8095 hurt quality in high-motion scenes.
8096 Unless there is an extremely high amount of motion, b_sensitivity can
8097 safely be lowered below the default; 10 is a reasonable value in most
8101 .B brd_scale=<0\-10>
8102 Downscales frames for dynamic B-frame decision (default: 0).
8103 Each time brd_scale is increased by one, the frame dimensions are
8104 divided by two, which improves speed by a factor of four.
8105 Both dimensions of the fully downscaled frame must be even numbers, so
8106 brd_scale=1 requires the original dimensions to be multiples of four,
8107 brd_scale=2 requires multiples of eight, etc.
8108 In other words, the dimensions of the original frame must both be
8109 divisible by 2^(brd_scale+1) with no remainder.
8112 .B bidir_refine=<0\-4>
8113 Refine the two motion vectors used in bidirectional macroblocks,
8114 rather than re-using vectors from the forward and backward searches.
8115 This option has no effect without B-frames.
8121 Use a wider search (larger values are slower).
8127 Activates internal two (or more) pass mode, only specify if you wish to
8128 use two (or more) pass encoding.
8132 first pass (also see turbo)
8136 Nth pass (second and subsequent passes of N-pass encoding)
8139 Here is how it works, and how to use it:
8141 The first pass (vpass=1) writes the statistics file.
8142 You might want to deactivate some CPU-hungry options, like "turbo"
8145 In two pass mode, the second pass (vpass=2) reads the statistics file and
8146 bases ratecontrol decisions on it.
8148 In N-pass mode, the second pass (vpass=3, that is not a typo)
8149 does both: It first reads the statistics, then overwrites them.
8150 You might want to backup divx2pass.log before doing this if there is
8151 any possibility that you will have to cancel MEncoder.
8152 You can use all encoding options, except very CPU-hungry options like "qns".
8154 You can run this same pass over and over to refine the encode.
8155 Each subsequent pass will use the statistics from the previous pass to improve.
8156 The final pass can include any CPU-hungry encoding options.
8158 If you want a 2 pass encode, use first vpass=1, and then vpass=2.
8160 If you want a 3 or more pass encode, use vpass=1 for the first pass
8161 and then vpass=3 and then vpass=3 again and again until you are
8162 satisfied with the encode.
8174 Encodes with an optimal Huffman table based upon statistics
8175 from the first pass.
8180 .B turbo (two pass only)
8181 Dramatically speeds up pass one using faster algorithms and disabling
8182 CPU-intensive options.
8183 This will probably reduce global PSNR a little bit (around 0.01dB) and
8184 change individual frame type and PSNR a little bit more (up to 0.03dB).
8188 Store movie aspect internally, just like with MPEG files.
8189 Much nicer than rescaling, because quality is not decreased.
8190 Only MPlayer will play these files correctly, other players will display
8191 them with wrong aspect.
8192 The aspect parameter can be given as a ratio or a floating point number.
8199 .IPs "aspect=16/9 or aspect=1.78"
8205 Same as the aspect option, but automatically computes aspect, taking
8206 into account all the adjustments (crop/\:expand/\:scale/\:etc.) made in the
8208 Does not incur a performance penalty, so you can safely leave it
8213 Specify bitrate (default: 800).
8221 .IPs 16001\-24000000
8228 approximated file size tolerance in kbit.
8229 1000\-100000 is a sane range.
8230 (warning: 1kbit = 1000 bits)
8234 vratetol should not be too large during the second pass or there might
8235 be problems if vrc_(min|max)rate is used.

8250 For MPEG-1/2 this also sets the vbv buffer size, use 327 for VCD,
8251 917 for SVCD and 1835 for DVD.
8254 .B vrc_buf_aggressivity
8260 Note that some of the ratecontrol-affecting options will have no effect
8261 if vrc_strategy is not set to 0.
8265 Use internal lavc ratecontrol (default).
8267 Use Xvid ratecontrol (experimental; requires MEncoder to be compiled
8268 with support for Xvid 1.1 or higher).
8273 .B vb_qfactor=<\-31.0\-31.0>
8274 quantizer factor between B- and non-B-frames (default: 1.25)
8277 .B vi_qfactor=<\-31.0\-31.0>
8278 quantizer factor between I- and non-I-frames (default: 0.8)
8281 .B vb_qoffset=<\-31.0\-31.0>
8282 quantizer offset between B- and non-B-frames (default: 1.25)
8285 .B vi_qoffset=<\-31.0\-31.0>
8288 if v{b|i}_qfactor > 0
8290 I/B-frame quantizer = P-frame quantizer * v{b|i}_qfactor + v{b|i}_qoffset
8294 do normal ratecontrol (do not lock to next P-frame quantizer) and
8295 set q= \-q * v{b|i}_qfactor + v{b|i}_qoffset
8298 To do constant quantizer encoding with different quantizers for
8299 I/P- and B-frames you can use:
8300 lmin= <ip_quant>:lmax= <ip_quant>:vb_qfactor= <b_quant/\:ip_quant>.
8303 .B vqblur=<0.0\-1.0> (pass one)
8304 Quantizer blur (default: 0.5), larger values will average the
8305 quantizer more over time (slower change).
8309 Quantizer blur disabled.
8311 Average the quantizer over all previous frames.
8316 .B vqblur=<0.0\-99.0> (pass two)
8317 Quantizer gaussian blur (default: 0.5), larger values will average
8318 the quantizer more over time (slower change).
8321 .B vqcomp=<0.0\-1.0>
8322 Quantizer compression, vrc_eq depends upon this (default: 0.5).

8425 Use a nice differentiable function (default).
8430 .B vlelim=<\-1000\-1000>

8432 Negative values will also consider the DC coefficient (should be at least \-4
8433 or lower for encoding at quant=1):
8444 .B vcelim=<\-1000\-1000>
8445 Sets single coefficient elimination threshold for chrominance.
8446 Negative values will also consider the DC coefficient (should be at least \-4
8447 or lower for encoding at quant=1):
8458 .B vstrict=<\-2|\-1|0|1>
8459 strict standard compliance
8465 Only recommended if you want to feed the output into the
8466 MPEG-4 reference decoder.
8468 Allow libavcodec specific extensions (default).
8470 Enables experimental codecs and features which may not be playable
8471 with future MPlayer versions (snow).
8478 Adds 2 Bytes per video packet, improves error-resistance when transferring over
8479 unreliable channels (e.g.\& streaming over the internet).
8480 Each video packet will be encoded in 3 separate partitions:
8485 .IPs "2. DC coefficients"
8487 .IPs "3. AC coefficients"
8492 MV & DC are most important, losing them looks far worse than losing
8493 the AC and the 1. & 2. partition.
8494 (MV & DC) are far smaller than the 3. partition (AC) meaning that errors
8495 will hit the AC partition much more often than the MV & DC partitions.
8496 Thus, the picture will look better with partitioning than without,
8497 as without partitioning an error will trash AC/\:DC/\:MV equally.

8559 libmpeg2mmx (inaccurate, do not use for encoding with keyint >100)
8590 .B lumi_mask=<0.0\-1.0>
8591 Luminance masking is a 'psychosensory' setting that is supposed to
8592 make use of the fact that the human eye tends to notice fewer details
8593 in very bright parts of the picture.
8594 Luminance masking compresses bright areas stronger than medium ones,
8595 so it will save bits that can be spent again on other frames, raising
8596 overall subjective quality, while possibly reducing PSNR.
8599 Be careful, overly large values can cause disastrous things.
8602 Large values might look good on some monitors but may look horrible
8614 .B dark_mask=<0.0\-1.0>
8615 Darkness masking is a 'psychosensory' setting that is supposed to
8616 make use of the fact that the human eye tends to notice fewer details
8617 in very dark parts of the picture.
8618 Darkness masking compresses dark areas stronger than medium ones,
8619 so it will save bits that can be spent again on other frames, raising
8620 overall subjective quality, while possibly reducing PSNR.
8623 Be careful, overly large values can cause disastrous things.
8626 Large values might look good on some monitors but may look horrible
8627 on other monitors / TV / TFT.
8638 .B tcplx_mask=<0.0\-1.0>
8639 Temporal complexity masking (default: 0.0 (disabled)).
8640 Imagine a scene with a bird flying across the whole scene; tcplx_mask
8641 will raise the quantizers of the bird's macroblocks (thus decreasing their
8642 quality), as the human eye usually does not have time to see all the bird's
8644 Be warned that if the masked object stops (e.g.\& the bird lands) it is
8645 likely to look horrible for a short period of time, until the encoder
8646 figures out that the object is not moving and needs refined blocks.
8647 The saved bits will be spent on other parts of the video, which may increase
8648 subjective quality, provided that tcplx_mask is carefully chosen.
8651 .B scplx_mask=<0.0\-1.0>
8652 Spatial complexity masking.
8653 Larger values help against blockiness, if no deblocking filter is used for
8654 decoding, which is maybe not a good idea.
8656 Imagine a scene with grass (which usually has great spatial complexity),
8657 a blue sky and a house; scplx_mask will raise the quantizers of the grass'
8658 macroblocks, thus decreasing its quality, in order to spend more bits on
8659 the sky and the house.
8662 Crop any black borders completely as they will reduce the quality
8663 of the macroblocks (also applies without scplx_mask).
8675 This setting does not have the same effect as using a custom matrix that
8676 would compress high frequencies harder, as scplx_mask will reduce the
8677 quality of P blocks even if only DC is changing.
8678 The result of scplx_mask will probably not look as good.
8682 .B p_mask=<0.0\-1.0> (also see vi_qfactor)
8683 Reduces the quality of inter blocks.
8684 This is equivalent to increasing the quality of intra blocks, because the
8685 same average bitrate will be distributed by the rate controller to the
8686 whole video sequence (default: 0.0 (disabled)).
8687 p_mask=1.0 doubles the bits allocated to each intra block.
8690 .B border_mask=<0.0\-1.0>
8691 border-processing for MPEG-style encoders.
8692 Border processing increases the quantizer for macroblocks which are less
8693 than 1/5th of the frame width/height away from the frame border,
8694 since they are often visually less important.
8698 Normalize adaptive quantization (experimental).
8699 When using adaptive quantization (*_mask), the average per-MB quantizer may no
8700 longer match the requested frame-level quantizer.

8854 5/3 wavelet, only used in snow
8856 9/7 wavelet, only used in snow
8858 Also use chroma, currently does not work (correctly) with B-frames.
8863 .B ildctcmp=<0\-2000>
8864 Sets the comparison function for interlaced DCT decision
8865 (see mbcmp for available comparison functions).
8869 Sets the comparison function for motion estimation pre pass
8870 (see mbcmp for available comparison functions) (default: 0).
8874 Sets the comparison function for full pel motion estimation
8875 (see mbcmp for available comparison functions) (default: 0).
8879 Sets the comparison function for sub pel motion estimation
8880 (see mbcmp for available comparison functions) (default: 0).
8883 .B skipcmp=<0\-2000>
8884 FIXME: Document this.
8887 .B nssew=<0\-1000000>
8888 This setting controls NSSE weight, where larger weights will result in
8890 0 NSSE is identical to SSE
8891 You may find this useful if you prefer to keep some noise in your encoded
8892 video rather than filtering it away before encoding (default: 8).
8896 diamond type and size for motion estimation pre-pass
8900 Diamond type & size for motion estimation.
8901 Motion search is an iterative process.
8902 Using a small diamond does not limit the search to finding only small
8904 It is just somewhat more likely to stop before finding the very best motion
8905 vector, especially when noise is involved.
8906 Bigger diamonds allow a wider search for the best motion vector, thus are
8907 slower but result in better quality.
8909 Big normal diamonds are better quality than shape-adaptive diamonds.
8911 Shape-adaptive diamonds are a good tradeoff between speed and quality.
8914 The sizes of the normal diamonds and shape adaptive ones do not have
8918 shape adaptive (fast) diamond with size 3
8920 shape adaptive (fast) diamond with size 2
8922 uneven multi-hexagon search (slow)
8924 normal size=1 diamond (default) =EPZS type diamond
8932 normal size=2 diamond
8945 Trellis searched quantization.
8946 This will find the optimal encoding for each 8x8 block.
8947 Trellis searched quantization is quite simply an optimal quantization in
8948 the PSNR versus bitrate sense (Assuming that there would be no rounding
8949 errors introduced by the IDCT, which is obviously not the case.).
8950 It simply finds a block for the minimum of error and lambda*bits.
8954 quantization parameter (QP) dependent constant
8956 amount of bits needed to encode the block
8958 sum of squared errors of the quantization
8964 Rate distorted optimal coded block pattern.
8965 Will select the coded block pattern which minimizes distortion + lambda*rate.
8966 This can only be used together with trellis quantization.
8970 Try to encode each MB with MV=<0,0> and choose the better one.
8971 This has no effect if mbd=0.
8974 .B mv0_threshold=<any non-negative integer>
8975 When surrounding motion vectors are <0,0> and the motion estimation
8976 score of the current block is less than mv0_threshold, <0,0> is used for
8977 the motion vector and further motion estimation is skipped (default:
8979 Lowering mv0_threshold to 0 can give a slight (0.01dB) PSNR increase and
8980 possibly make the encoded video look slightly better; raising
8981 mv0_threshold past 320 results in diminished PSNR and visual quality.
8982 Higher values speed up encoding very slightly (usually less than 1%,
8983 depending on the other options used).
8986 This option does not require mv0 to be enabled.
8989 .B qprd (mbd=2 only)
8990 rate distorted optimal quantization parameter (QP) for the given
8991 lambda of each macroblock
8994 .B last_pred=<0\-99>
8995 amount of motion predictors from the previous frame
9001 Will use 2a+1 x 2a+1 macroblock square of motion vector predictors from the
9008 motion estimation pre-pass
9014 only after I-frames (default)
9022 subpel refinement quality (for qpel) (default: 8 (high quality))
9025 This has a significant effect on speed.
9029 number of reference frames to consider for motion compensation
9030 (Snow only) (default: 1)
9034 print the PSNR (peak signal to noise ratio) for the whole video after encoding
9035 and store the per frame PSNR in a file with a name like 'psnr_hhmmss.log'.
9036 Returned values are in dB (decibel), the higher the better.
9040 Use MPEG quantizers instead of H.263.
9044 Enable AC prediction for MPEG-4 or advanced intra prediction for H.263+.
9045 This will improve quality very slightly (around 0.02 dB PSNR) and slow
9046 down encoding very slightly (about 1%).
9049 vqmin should be 8 or larger for H.263+ AIC.
9053 alternative inter vlc for H.263+
9057 unlimited MVs (H.263+ only)
9058 Allows encoding of arbitrarily long MVs.
9061 .B ibias=<\-256\-256>
9062 intra quantizer bias (256 equals 1.0, MPEG style quantizer default: 96,
9063 H.263 style quantizer default: 0)
9066 The H.263 MMX quantizer cannot handle positive biases (set vfdct=1 or 2),
9067 the MPEG MMX quantizer cannot handle negative biases (set vfdct=1 or 2).
9070 .B pbias=<\-256\-256>
9071 inter quantizer bias (256 equals 1.0, MPEG style quantizer default: 0,
9072 H.263 style quantizer default: \-64)
9075 The H.263 MMX quantizer cannot handle positive biases (set vfdct=1 or 2),
9076 the MPEG MMX quantizer cannot handle negative biases (set vfdct=1 or 2).
9079 A more positive bias (\-32 \- \-16 instead of \-64) seems to improve the PSNR.
9083 Noise reduction, 0 means disabled.
9084 0\-600 is a useful range for typical content, but you may want to turn it
9085 up a bit more for very noisy content (default: 0).
9086 Given its small impact on speed, you might want to prefer to use this over
9087 filtering noise away with video filters like denoise3d or hqdn3d.
9091 Quantizer noise shaping.
9092 Rather than choosing quantization to most closely match the source video
9093 in the PSNR sense, it chooses quantization such that noise (usually ringing)
9094 will be masked by similar-frequency content in the image.
9095 Larger values are slower but may not result in better quality.
9096 This can and should be used together with trellis quantization, in which case
9097 the trellis quantization (optimal for constant weight) will be used as
9098 startpoint for the iterative search.
9104 Only lower the absolute value of coefficients.
9106 Only change coefficients before the last non-zero coefficient + 1.
9113 .B inter_matrix=<comma separated matrix>
9114 Use custom inter matrix.
9115 It needs a comma separated string of 64 integers.
9118 .B intra_matrix=<comma separated matrix>
9119 Use custom intra matrix.
9120 It needs a comma separated string of 64 integers.
9124 experimental quantizer modulation
9128 experimental quantizer modulation
9132 intra DC precision in bits (default: 8).
9133 If you specify vcodec=mpeg2video this value can be 8, 9, 10 or 11.
9136 .B cgop (also see sc_threshold)
9138 Currently it only works if scene change detection is disabled
9139 (sc_threshold=1000000000).
9143 Enable Global Motion Compensation.
9147 Sets the low delay flag for MPEG-1/2 (disables B-frames).
9151 Control writing global video headers.
9155 Codec decides where to write global headers (default).
9157 Write global headers only in extradata (needed for .mp4/MOV/NUT).
9159 Write global headers only in front of keyframes.
9167 Same as vglobal for audio headers.
9171 Set CodecContext Level.
9172 Use 31 or 41 to play video on a Playstation 3.

9189 Nuppel video is based on RTJPEG and LZO.
9190 By default frames are first encoded with RTJPEG and then compressed with LZO,
9191 but it is possible to disable either or both of the two passes.
9192 As a result, you can in fact output raw i420, LZO compressed i420, RTJPEG,
9193 or the default LZO compressed RTJPEG.
9196 The nuvrec documentation contains some advice and examples about the
9197 settings to use for the most common TV encodings.
9201 chrominance threshold (default: 1)
9205 luminance threshold (default: 1)
9209 Enable LZO compression (default).
9213 Disable LZO compression.
9217 quality level (default: 255)
9221 Disable RTJPEG encoding.
9225 Enable RTJPEG encoding (default).
9228 .SS xvidenc (\-xvidencopts)
9230 There are three modes available: constant bitrate (CBR), fixed quantizer and
9235 Specify the pass in two pass mode.
9238 .B turbo (two pass only)
9239 Dramatically speeds up pass one using faster algorithms and disabling
9240 CPU-intensive options.
9241 This will probably reduce global PSNR a little bit and change individual
9242 frame type and PSNR a little bit more.
9245 .B bitrate=<value> (CBR or two pass mode)
9246 Sets the bitrate to be used in kbits/\:second if <16000 or in bits/\:second
9248 If <value> is negative, Xvid will use its absolute value as the target size
9249 (in kBytes) of the video and compute the associated bitrate automagically
9250 (default: 687 kbits/s).
9253 .B fixed_quant=<1\-31>
9254 Switch to fixed quantizer mode and specify the quantizer to be used.
9257 .B zones=<zone0>[/<zone1>[/...]] (CBR or two pass mode)
9258 User specified quality for specific parts (ending, credits, ...).
9259 Each zone is <start-frame>,<mode>,<value> where <mode> may be
9263 Constant quantizer override, where value=<2.0\-31.0>
9264 represents the quantizer value.
9266 Ratecontrol weight override, where value=<0.01\-2.00>
9267 represents the quality correction in %.
9276 .IPs zones=90000,q,20
9277 Encodes all frames starting with frame 90000 at constant quantizer 20.
9278 .IPs zones=0,w,0.1/10001,w,1.0/90000,q,20
9279 Encode frames 0\-10000 at 10% bitrate, encode frames 90000
9280 up to the end at constant quantizer 20.
9281 Note that the second zone is needed to delimit the first zone, as
9282 without it everything up until frame 89999 would be encoded at 10%
9288 .B me_quality=<0\-6>
9289 This option controls the motion estimation subsystem.
9290 The higher the value, the more precise the estimation should be (default: 6).
9291 The more precise the motion estimation is, the more bits can be saved.
9292 Precision is gained at the expense of CPU time so decrease this setting if
9293 you need realtime encoding.
9297 MPEG-4 uses a half pixel precision for its motion search by default.
9298 The standard proposes a mode where encoders are allowed to use quarter
9300 This option usually results in a sharper image.
9301 Unfortunately it has a great impact on bitrate and sometimes the
9302 higher bitrate use will prevent it from giving a better image
9303 quality at a fixed bitrate.
9304 It is better to test with and without this option and see whether it
9305 is worth activating.
9309 Enable Global Motion Compensation, which makes Xvid generate special
9310 frames (GMC-frames) which are well suited for Pan/\:Zoom/\:Rotating images.
9311 Whether or not the use of this option will save bits is highly
9312 dependent on the source material.
9316 Trellis Quantization is a kind of adaptive quantization method that
9317 saves bits by modifying quantized coefficients to make them more
9318 compressible by the entropy encoder.
9319 Its impact on quality is good, and if VHQ uses too much CPU for you,
9320 this setting can be a good alternative to save a few bits (and gain
9321 quality at fixed bitrate) at a lesser cost than with VHQ (default: on).
9325 Activate this if your encoded sequence is an anime/\:cartoon.
9326 It modifies some Xvid internal thresholds so Xvid takes better decisions on
9327 frame types and motion vectors for flat looking cartoons.
9331 The usual motion estimation algorithm uses only the luminance information to
9332 find the best motion vector.
9333 However for some video material, using the chroma planes can help find
9335 This setting toggles the use of chroma planes for motion estimation
9340 Enable a chroma optimizer prefilter.
9341 It will do some extra magic on color information to minimize the
9342 stepped-stairs effect on edges.
9343 It will improve quality at the cost of encoding speed.
9344 It reduces PSNR by nature, as the mathematical deviation to the original
9345 picture will get bigger, but the subjective image quality will raise.
9346 Since it works with color information, you might want to turn it off when
9347 encoding in grayscale.
9351 Activates high-quality prediction of AC coefficients for intra frames from
9352 neighbor blocks (default: on).
9356 The motion search algorithm is based on a search in the usual color domain
9357 and tries to find a motion vector that minimizes the difference between the
9358 reference frame and the encoded frame.
9359 With this setting activated, Xvid will also use the frequency domain (DCT)
9360 to search for a motion vector that minimizes not only the spatial
9361 difference but also the encoding length of the block.
9368 mode decision (inter/\:intra MB) (default)
9380 Adaptive quantization allows the macroblock quantizers to vary inside
9382 This is a 'psychosensory' setting that is supposed to make use of the
9383 fact that the human eye tends to notice fewer details in very bright
9384 and very dark parts of the picture.
9385 It compresses those areas more strongly than medium ones, which will
9386 save bits that can be spent again on other frames, raising overall
9387 subjective quality and possibly reducing PSNR.
9391 Make Xvid discard chroma planes so the encoded video is grayscale only.
9392 Note that this does not speed up encoding, it just prevents chroma data
9393 from being written in the last stage of encoding.
9397 Encode the fields of interlaced video material.
9398 Turn this option on for interlaced content.
9401 Should you rescale the video, you would need an interlace-aware resizer,
9402 which you can activate with \-vf scale=<width>:<height>:1.
9405 .B min_iquant=<0\-31>
9406 minimum I-frame quantizer (default: 2)
9409 .B max_iquant=<0\-31>
9410 maximum I-frame quantizer (default: 31)
9413 .B min_pquant=<0\-31>
9414 minimum P-frame quantizer (default: 2)
9417 .B max_pquant=<0\-31>
9418 maximum P-frame quantizer (default: 31)
9421 .B min_bquant=<0\-31>
9422 minimum B-frame quantizer (default: 2)
9425 .B max_bquant=<0\-31>
9426 maximum B-frame quantizer (default: 31)
9429 .B min_key_interval=<value> (two pass only)
9430 minimum interval between keyframes (default: 0)
9433 .B max_key_interval=<value>
9434 maximum interval between keyframes (default: 10*fps)
9437 .B quant_type=<h263|mpeg>
9438 Sets the type of quantizer to use.
9439 For high bitrates, you will find that MPEG quantization preserves more detail.
9440 For low bitrates, the smoothing of H.263 will give you less block noise.
9441 When using custom matrices, MPEG quantization
9446 .B quant_intra_matrix=<filename>
9447 Load a custom intra matrix file.
9448 You can build such a file with xvid4conf's matrix editor.
9451 .B quant_inter_matrix=<filename>
9452 Load a custom inter matrix file.
9453 You can build such a file with xvid4conf's matrix editor.
9456 .B keyframe_boost=<0\-1000> (two pass mode only)
9457 Shift some bits from the pool for other frame types to intra frames,
9458 thus improving keyframe quality.
9459 This amount is an extra percentage, so a value of 10 will give
9460 your keyframes 10% more bits than normal
9464 .B kfthreshold=<value> (two pass mode only)
9465 Works together with kfreduction.
9466 Determines the minimum distance below which you consider that
9467 two frames are considered consecutive and treated differently
9468 according to kfreduction
9472 .B kfreduction=<0\-100> (two pass mode only)
9473 The above two settings can be used to adjust the size of keyframes that
9474 you consider too close to the first (in a row).
9475 kfthreshold sets the range in which keyframes are reduced, and
9476 kfreduction determines the bitrate reduction they get.
9477 The last I-frame will get treated normally
9481 .B max_bframes=<0\-4>
9482 Maximum number of B-frames to put between I/P-frames (default: 2).
9485 .B bquant_ratio=<0\-1000>
9486 quantizer ratio between B- and non-B-frames, 150=1.50 (default: 150)
9489 .B bquant_offset=<\-1000\-1000>
9490 quantizer offset between B- and non-B-frames, 100=1.00 (default: 100)
9493 .B bf_threshold=<\-255\-255>
9494 This setting allows you to specify what priority to place on the use of
9496 The higher the value, the higher the probability of B-frames being used
9498 Do not forget that B-frames usually have a higher quantizer, and therefore
9499 aggressive production of B-frames may cause worse visual quality.
9503 This option tells Xvid to close every GOP (Group Of Pictures bounded
9504 by two I-frames), which makes GOPs independent from each other.
9505 This just implies that the last frame of the GOP is either a P-frame or a
9506 N-frame but not a B-frame.
9507 It is usually a good idea to turn this option on (default: on).
9511 This option is meant to solve frame-order issues when encoding to
9512 container formats like AVI that cannot cope with out-of-order frames.
9513 In practice, most decoders (both software and hardware) are able to deal
9514 with frame-order themselves, and may get confused when this option is
9515 turned on, so you can safely leave if off, unless you really know what
9519 This will generate an illegal bitstream, and will not be
9520 decodable by ISO-MPEG-4 decoders except DivX/\:libavcodec/\:Xvid.
9523 This will also store a fake DivX version in the file so the bug
9524 autodetection of some decoders might be confused.
9527 .B frame_drop_ratio=<0\-100> (max_bframes=0 only)
9528 This setting allows the creation of variable framerate video streams.
9529 The value of the setting specifies a threshold under which, if the
9530 difference of the following frame to the previous frame is below or equal
9531 to this threshold, a frame gets not coded (a so called n-vop is placed
9533 On playback, when reaching an n-vop the previous frame will be displayed.
9536 Playing with this setting may result in a jerky video, so use it at your
9540 .B rc_reaction_delay_factor=<value>
9541 This parameter controls the number of frames the CBR rate controller
9542 will wait before reacting to bitrate changes and compensating for them
9543 to obtain a constant bitrate over an averaging range of frames.
9546 .B rc_averaging_period=<value>
9547 Real CBR is hard to achieve.
9548 Depending on the video material, bitrate can be variable, and hard to predict.
9549 Therefore Xvid uses an averaging period for which it guarantees a given
9550 amount of bits (minus a small variation).
9551 This settings expresses the "number of frames" for which Xvid averages
9552 bitrate and tries to achieve CBR.
9555 .B rc_buffer=<value>
9556 size of the rate control buffer
9559 .B curve_compression_high=<0\-100>
9560 This setting allows Xvid to take a certain percentage of bits away from
9561 high bitrate scenes and give them back to the bit reservoir.
9562 You could also use this if you have a clip with so many bits allocated
9563 to high-bitrate scenes that the low(er)-bitrate scenes start to look bad
9567 .B curve_compression_low=<0\-100>
9568 This setting allows Xvid to give a certain percentage of extra bits to the
9569 low bitrate scenes, taking a few bits from the entire clip.
9570 This might come in handy if you have a few low-bitrate scenes that are
9571 still blocky (default: 0).
9574 .B overflow_control_strength=<0\-100>
9575 During pass one of two pass encoding, a scaled bitrate curve is computed.
9576 The difference between that expected curve and the result obtained during
9577 encoding is called overflow.
9578 Obviously, the two pass rate controller tries to compensate for that overflow,
9579 distributing it over the next frames.
9580 This setting controls how much of the overflow is distributed every time
9581 there is a new frame.
9582 Low values allow lazy overflow control, big rate bursts are compensated for
9583 more slowly (could lead to lack of precision for small clips).
9584 Higher values will make changes in bit redistribution more abrupt, possibly
9585 too abrupt if you set it too high, creating artifacts (default: 5).
9588 This setting impacts quality a lot, play with it carefully!
9591 .B max_overflow_improvement=<0\-100>
9592 During the frame bit allocation, overflow control may increase the frame
9594 This parameter specifies the maximum percentage by which the overflow
9595 control is allowed to increase the frame size, compared to the ideal curve
9600 .B max_overflow_degradation=<0\-100>
9601 During the frame bit allocation, overflow control may decrease the frame
9603 This parameter specifies the maximum percentage by which the overflow
9604 control is allowed to decrease the frame size, compared to the ideal curve
9609 .B container_frame_overhead=<0...>
9610 Specifies a frame average overhead per frame, in bytes.
9611 Most of the time users express their target bitrate for video w/o taking
9612 care of the video container overhead.
9613 This small but (mostly) constant overhead can cause the target file size
9615 Xvid allows users to set the amount of overhead per frame the
9616 container generates (give only an average per frame).
9617 0 has a special meaning, it lets Xvid use its own default values
9618 (default: 24 \- AVI average overhead).
9621 .B profile=<profile_name>
9622 Restricts options and VBV (peak bitrate over a short period) according to
9623 the Simple, Advanced Simple and DivX profiles.
9624 The resulting videos should be playable on standalone players adhering to these
9625 profile specifications.
9629 no restrictions (default)
9631 simple profile at level 0
9633 simple profile at level 1
9635 simple profile at level 2
9637 simple profile at level 3
9639 advanced simple profile at level 0
9641 advanced simple profile at level 1
9643 advanced simple profile at level 2
9645 advanced simple profile at level 3
9647 advanced simple profile at level 4
9649 advanced simple profile at level 5
9651 DXN handheld profile
9653 DXN portable NTSC profile
9655 DXN portable PAL profile
9657 DXN home theater NTSC profile
9659 DXN home theater PAL profile
9666 These profiles should be used in conjunction with an appropriate \-ffourcc.
9667 Generally DX50 is applicable, as some players do not recognize Xvid but
9668 most recognize DivX.
9673 Specifies the Pixel Aspect Ratio mode (not to be confused with DAR,
9674 the Display Aspect Ratio).
9675 PAR is the ratio of the width and height of a single pixel.
9676 So both are related like this: DAR = PAR * (width/height).
9678 MPEG-4 defines 5 pixel aspect ratios and one extended
9679 one, giving the opportunity to specify a specific pixel aspect
9681 5 standard modes can be specified:
9685 It is the usual PAR for PC content.
9686 Pixels are a square unit.
9688 PAL standard 4:3 PAR.
9689 Pixels are rectangles.
9695 same as above (Do not forget to give the exact ratio.)
9697 Allows you to specify your own pixel aspect ratio with par_width and
9703 In general, setting aspect and autoaspect options is enough.
9707 .B par_width=<1\-255> (par=ext only)
9708 Specifies the width of the custom pixel aspect ratio.
9711 .B par_height=<1\-255> (par=ext only)
9712 Specifies the height of the custom pixel aspect ratio.
9715 .B aspect=<x/y | f (float value)>
9716 Store movie aspect internally, just like MPEG files.
9717 Much nicer solution than rescaling, because quality is not decreased.
9718 MPlayer and a few others players will play these files correctly, others
9719 will display them with the wrong aspect.
9720 The aspect parameter can be given as a ratio or a floating point number.
9724 Same as the aspect option, but automatically computes aspect, taking
9725 into account all the adjustments (crop/\:expand/\:scale/\:etc.) made in the
9730 Print the PSNR (peak signal to noise ratio) for the whole video after encoding
9731 and store the per frame PSNR in a file with a name like 'psnr_hhmmss.log' in
9732 the current directory.
9733 Returned values are in dB (decibel), the higher the better.
9737 Save per-frame statistics in ./xvid.dbg. (This is not the two pass control
9743 The following option is only available in Xvid 1.1.x.
9747 This setting allows vector candidates for B-frames to be used for
9748 the encoding chosen using a rate distortion optimized operator,
9749 which is what is done for P-frames by the vhq option.
9750 This produces nicer-looking B-frames while incurring almost no
9751 performance penalty (default: 1).
9755 The following option is only available in the 1.2.x version of Xvid.
9759 Create n threads to run the motion estimation (default: 0).
9760 The maximum number of threads that can be used is the picture height
9764 .SS x264enc (\-x264encopts)
9768 Sets the average bitrate to be used in kbits/\:second (default: off).
9769 Since local bitrate may vary, this average may be inaccurate for
9770 very short videos (see ratetol).
9771 Constant bitrate can be achieved by combining this with vbv_maxrate,
9772 at significant reduction in quality.
9776 This selects the quantizer to use for P-frames.
9777 I- and B-frames are offset from this value by ip_factor and pb_factor, respectively.
9778 20\-40 is a useful range.
9779 Lower values result in better fidelity, but higher bitrates.
9781 Note that quantization in H.264 works differently from MPEG-1/2/4:
9782 H.264's quantization parameter (QP) is on a logarithmic scale.
9783 The mapping is approximately H264QP = 12 + 6*log2(MPEGQP).
9784 For example, MPEG at QP=2 is equivalent to H.264 at QP=18.
9788 Enables constant quality mode, and selects the quality.
9789 The scale is similar to QP.
9790 Like the bitrate-based modes, this allows each frame to use a
9791 different QP based on the frame's complexity.
9795 Enable 2 or 3-pass mode.
9796 It is recommended to always encode in 2 or 3-pass mode as it leads to a
9797 better bit distribution and improves overall quality.
9803 second pass (of two pass encoding)
9805 Nth pass (second and third passes of three pass encoding)
9808 Here is how it works, and how to use it:
9810 The first pass (pass=1) collects statistics on the video and writes them
9812 You might want to deactivate some CPU-hungry options, apart from the ones
9813 that are on by default.
9815 In two pass mode, the second pass (pass=2) reads the statistics file and
9816 bases ratecontrol decisions on it.
9818 In three pass mode, the second pass (pass=3, that is not a typo)
9819 does both: It first reads the statistics, then overwrites them.
9820 You can use all encoding options, except very CPU-hungry options.
9822 The third pass (pass=3) is the same as the second pass, except that it has
9823 the second pass' statistics to work from.
9824 You can use all encoding options, including CPU-hungry ones.
9826 The first pass may use either average bitrate or constant quantizer.
9827 ABR is recommended, since it does not require guessing a quantizer.
9828 Subsequent passes are ABR, and must specify bitrate.
9833 Fast first pass mode.
9834 During the first pass of a two or more pass encode it is possible to gain
9835 speed by disabling some options with negligible or even no impact on the
9836 final pass output quality.
9842 Reduce subq, frameref and disable some inter-macroblock partition analysis
9845 Reduce subq and frameref to 1, use a diamond ME search and disable all
9846 partition analysis modes.
9849 Level 1 can increase first pass speed up to 2x with no change in the global
9850 PSNR of the final pass compared to a full quality first pass.
9852 Level 2 can increase first pass speed up to 4x with about +/\- 0.05dB change
9853 in the global PSNR of the final pass compared to a full quality first pass.
9858 Sets maximum interval between IDR-frames (default: 250).
9859 Larger values save bits, thus improve quality, at the cost of seeking
9861 Unlike MPEG-1/2/4, H.264 does not suffer from DCT drift with large
9865 .B keyint_min=<1\-keyint/2>
9866 Sets minimum interval between IDR-frames (default: 25).
9867 If scenecuts appear within this interval, they are still encoded as
9868 I-frames, but do not start a new GOP.
9869 In H.264, I-frames do not necessarily bound a closed GOP because it is
9870 allowable for a P-frame to be predicted from more frames than just the one
9871 frame before it (also see frameref).
9872 Therefore, I-frames are not necessarily seekable.
9873 IDR-frames restrict subsequent P-frames from referring to any frame
9874 prior to the IDR-frame.
9877 .B scenecut=<\-1\-100>
9878 Controls how aggressively to insert extra I-frames (default: 40).
9879 With small values of scenecut, the codec often has to force an I-frame
9880 when it would exceed keyint.
9881 Good values of scenecut may find a better location for the I-frame.
9882 Large values use more I-frames than necessary, thus wasting bits.
9883 \-1 disables scene-cut detection, so I-frames are inserted only once
9884 every other keyint frames, even if a scene-cut occurs earlier.
9885 This is not recommended and wastes bitrate as scenecuts encoded as P-frames
9886 are just as big as I-frames, but do not reset the "keyint counter".
9890 Number of previous frames used as predictors in B- and P-frames (default: 1).
9891 This is effective in anime, but in live-action material the improvements
9892 usually drop off very rapidly above 6 or so reference frames.
9893 This has no effect on decoding speed, but does increase the memory needed for
9895 Some decoders can only handle a maximum of 15 reference frames.
9899 maximum number of consecutive B-frames between I- and P-frames (default: 0)
9903 Automatically decides when to use B-frames and how many, up to the maximum
9904 specified above (default: on).
9905 If this option is disabled, then the maximum number of B-frames is used.
9908 .B b_bias=<\-100\-100>
9909 Controls the decision performed by b_adapt.
9910 A higher b_bias produces more B-frames (default: 0).
9914 Allows B-frames to be used as references for predicting other frames.
9915 For example, consider 3 consecutive B-frames: I0 B1 B2 B3 P4.
9916 Without this option, B-frames follow the same pattern as MPEG-[124].
9917 So they are coded in the order I0 P4 B1 B2 B3, and all the B-frames
9918 are predicted from I0 and P4.
9919 With this option, they are coded as I0 P4 B2 B1 B3.
9920 B2 is the same as above, but B1 is predicted from I0 and B2, and
9921 B3 is predicted from B2 and P4.
9922 This usually results in slightly improved compression, at almost no
9924 However, this is an experimental option: it is not fully tuned and
9925 may not always help.
9926 Requires bframes >= 2.
9927 Disadvantage: increases decoding delay to 2 frames.
9931 Use deblocking filter (default: on).
9932 As it takes very little time compared to its quality gain, it is not
9933 recommended to disable it.
9936 .B deblock=<\-6\-6>,<\-6\-6>
9937 The first parameter is AlphaC0 (default: 0).
9938 This adjusts thresholds for the H.264 in-loop deblocking filter.
9939 First, this parameter adjusts the maximum amount of change that the filter is
9940 allowed to cause on any one pixel.
9941 Secondly, this parameter affects the threshold for difference across the
9942 edge being filtered.
9943 A positive value reduces blocking artifacts more, but will also smear details.
9945 The second parameter is Beta (default: 0).
9946 This affects the detail threshold.
9947 Very detailed blocks are not filtered, since the smoothing caused by the
9948 filter would be more noticeable than the original blocking.
9950 The default behavior of the filter almost always achieves optimal quality,
9951 so it is best to either leave it alone, or make only small adjustments.
9952 However, if your source material already has some blocking or noise which
9953 you would like to remove, it may be a good idea to turn it up a little bit.
9957 Use CABAC (Context-Adaptive Binary Arithmetic Coding) (default: on).
9958 Slightly slows down encoding and decoding, but should save 10\-15% bitrate.
9959 Unless you are looking for decoding speed, you should not disable it.
9962 .B qp_min=<1\-51> (ABR or two pass)
9963 Minimum quantizer, 10\-30 seems to be a useful range (default: 10).
9966 .B qp_max=<1\-51> (ABR or two pass)
9967 maximum quantizer (default: 51)
9970 .B qp_step=<1\-50> (ABR or two pass)
9971 maximum value by which the quantizer may be incremented/decremented between
9975 .B ratetol=<0.1\-100.0> (ABR or two pass)
9976 allowed variance in average bitrate (no particular units) (default: 1.0)
9979 .B vbv_maxrate=<value> (ABR or two pass)
9980 maximum local bitrate, in kbits/\:second (default: disabled)
9983 .B vbv_bufsize=<value> (ABR or two pass)
9984 averaging period for vbv_maxrate, in kbits
9985 (default: none, must be specified if vbv_maxrate is enabled)
9988 .B vbv_init=<0.0\-1.0> (ABR or two pass)
9989 initial buffer occupancy, as a fraction of vbv_bufsize (default: 0.9)
9992 .B ip_factor=<value>
9993 quantizer factor between I- and P-frames (default: 1.4)
9996 .B pb_factor=<value>
9997 quantizer factor between P- and B-frames (default: 1.3)
10000 .B qcomp=<0\-1> (ABR or two pass)
10001 quantizer compression (default: 0.6).
10002 A lower value makes the bitrate more constant,
10003 while a higher value makes the quantization parameter more constant.
10006 .B cplx_blur=<0\-999> (two pass only)
10007 Temporal blur of the estimated frame complexity, before curve compression
10009 Lower values allow the quantizer value to jump around more,
10010 higher values force it to vary more smoothly.
10011 cplx_blur ensures that each I-frame has quality comparable to the following
10012 P-frames, and ensures that alternating high and low complexity frames
10013 (e.g. low fps animation) do not waste bits on fluctuating quantizer.
10016 .B qblur=<0\-99> (two pass only)
10017 Temporal blur of the quantization parameter, after curve compression
10019 Lower values allow the quantizer value to jump around more,
10020 higher values force it to vary more smoothly.
10023 .B zones=<zone0>[/<zone1>[/...]]
10024 User specified quality for specific parts (ending, credits, ...).
10025 Each zone is <start-frame>,<end-frame>,<option> where option may be
10030 .IPs "b=<0.01\-100.0>"
10036 The quantizer option is not strictly enforced.
10037 It affects only the planning stage of ratecontrol, and is still subject
10038 to overflow compensation and qp_min/qp_max.
10042 .B direct_pred=<name>
10043 Determines the type of motion prediction used for direct macroblocks
10048 Direct macroblocks are not used.
10050 Motion vectors are extrapolated from neighboring blocks.
10053 Motion vectors are extrapolated from the following P-frame.
10055 The codec selects between spatial and temporal for each frame.
10059 Spatial and temporal are approximately the same speed and PSNR,
10060 the choice between them depends on the video content.
10061 Auto is slightly better, but slower.
10062 Auto is most effective when combined with multipass.
10063 direct_pred=none is both slower and lower quality.
10068 Use weighted prediction in B-frames.
10069 Without this option, bidirectionally predicted macroblocks give
10070 equal weight to each reference frame.
10071 With this option, the weights are determined by the temporal position
10072 of the B-frame relative to the references.
10073 Requires bframes > 1.
10076 .B partitions=<list>
10077 Enable some optional macroblock types (default: p8x8,b8x8,i8x8,i4x4).
10081 Enable types p16x8, p8x16, p8x8.
10083 Enable types p8x4, p4x8, p4x4.
10084 p4x4 is recommended only with subq >= 5, and only at low resolutions.
10086 Enable types b16x8, b8x16, b8x8.
10089 i8x8 has no effect unless 8x8dct is enabled.
10093 Enable all of the above types.
10095 Disable all of the above types.
10099 Regardless of this option, macroblock types p16x16, b16x16, and i16x16
10100 are always enabled.
10102 The idea is to find the type and size that best describe a certain area
10104 For example, a global pan is better represented by 16x16 blocks, while
10105 small moving objects are better represented by smaller blocks.
10110 Adaptive spatial transform size: allows macroblocks to choose between
10112 Also allows the i8x8 macroblock type.
10113 Without this option, only 4x4 DCT is used.
10117 Select fullpixel motion estimation algorithm.
10121 diamond search, radius 1 (fast)
10123 hexagon search, radius 2 (default)
10125 uneven multi-hexagon search (slow)
10127 exhaustive search (very slow, and no better than umh)
10132 .B me_range=<4\-64>
10133 radius of exhaustive or multi-hexagon motion search (default: 16)
10137 Adjust subpel refinement quality.
10138 This parameter controls quality versus speed tradeoffs involved in the motion
10139 estimation decision process.
10140 subq=5 can compress up to 10% better than subq=1.
10144 Runs fullpixel precision motion estimation on all candidate
10146 Then selects the best type with SAD metric (faster than subq=1, not recommended
10147 unless you're looking for ultra-fast encoding).
10149 Does as 0, then refines the motion of that type to fast quarterpixel precision
10152 Runs halfpixel precision motion estimation on all candidate macroblock types.
10153 Then selects the best type with SATD metric.
10154 Then refines the motion of that type to fast quarterpixel precision.
10156 As 2, but uses a slower quarterpixel refinement.
10158 Runs fast quarterpixel precision motion estimation on all candidate
10160 Then selects the best type with SATD metric.
10161 Then finishes the quarterpixel refinement for that type.
10163 Runs best quality quarterpixel precision motion estimation on all
10164 candidate macroblock types, before selecting the best type.
10165 Also refines the two motion vectors used in bidirectional macroblocks with
10166 SATD metric, rather than reusing vectors from the forward and backward
10169 Enables rate-distortion optimization of macroblock types in
10170 I- and P-frames (default).
10172 Enables rate-distortion optimization of macroblock types in all frames.
10174 Enables rate-distortion optimization of motion vectors and intra prediction modes in I- and P-frames.
10176 Enables rate-distortion optimization of motion vectors and intra prediction modes in all frames (best).
10180 In the above, "all candidates" does not exactly mean all enabled types:
10181 4x4, 4x8, 8x4 are tried only if 8x8 is better than 16x16.
10186 Takes into account chroma information during subpixel motion search
10187 (default: enabled).
10192 Allows each 8x8 or 16x8 motion partition to independently select a
10194 Without this option, a whole macroblock must use the same reference.
10195 Requires frameref>1.
10198 .B trellis=<0\-2> (cabac only)
10199 rate-distortion optimal quantization
10205 enabled only for the final encode
10207 enabled during all mode decisions (slow, requires subq>=6)
10212 .B psy-rd=rd[,trell]
10213 Sets the strength of the psychovisual optimization.
10216 .IPs rd=<0.0\-10.0>
10217 psy optimization strength (requires subq>=6) (default: 1.0)
10218 .IPs trell=<0.0\-10.0>
10219 trellis (requires trellis, experimental) (default: 0.0)
10225 .B deadzone_inter=<0\-32>
10226 Set the size of the inter luma quantization deadzone for non-trellis
10227 quantization (default: 21).
10228 Lower values help to preserve fine details and film grain (typically useful
10229 for high bitrate/quality encode), while higher values help filter out
10230 these details to save bits that can be spent again on other macroblocks
10231 and frames (typically useful for bitrate-starved encodes).
10232 It is recommended that you start by tweaking deadzone_intra before changing
10236 .B deadzone_intra=<0\-32>
10237 Set the size of the intra luma quantization deadzone for non-trellis
10238 quantization (default: 11).
10239 This option has the same effect as deadzone_inter except that it affects
10241 It is recommended that you start by tweaking this parameter before changing
10246 Performs early skip detection in P-frames (default: enabled).
10247 This usually improves speed at no cost, but it can sometimes produce
10248 artifacts in areas with no details, like sky.
10251 .B (no)dct_decimate
10252 Eliminate dct blocks in P-frames containing only a small single coefficient
10253 (default: enabled).
10254 This will remove some details, so it will save bits that can be spent
10255 again on other frames, hopefully raising overall subjective quality.
10256 If you are compressing non-anime content with a high target bitrate, you
10257 may want to disable this to preserve as much detail as possible.
10261 Noise reduction, 0 means disabled.
10262 100\-1000 is a useful range for typical content, but you may want to turn it
10263 up a bit more for very noisy content (default: 0).
10264 Given its small impact on speed, you might want to prefer to use this over
10265 filtering noise away with video filters like denoise3d or hqdn3d.
10268 .B chroma_qp_offset=<\-12\-12>
10269 Use a different quantizer for chroma as compared to luma.
10270 Useful values are in the range <\-2\-2> (default: 0).
10274 Defines how adaptive quantization (AQ) distributes bits:
10280 Avoid moving bits between frames.
10282 Move bits between frames (by default).
10287 .B aq_strength=<positive float value>
10288 Controls how much adaptive quantization (AQ) reduces blocking and blurring
10289 in flat and textured areas (default: 1.0).
10290 A value of 0.5 will lead to weak AQ and less details, when a value of 1.5
10291 will lead to strong AQ and more details.
10294 .B cqm=<flat|jvt|<filename>>
10295 Either uses a predefined custom quantization matrix or loads a JM format
10300 Use the predefined flat 16 matrix (default).
10302 Use the predefined JVT matrix.
10304 Use the provided JM format matrix file.
10309 Windows CMD.EXE users may experience problems with parsing the command line
10310 if they attempt to use all the CQM lists.
10311 This is due to a command line length limitation.
10312 In this case it is recommended the lists be put into a JM format CQM
10313 file and loaded as specified above.
10317 .B cqm4iy=<list> (also see cqm)
10318 Custom 4x4 intra luminance matrix, given as a list of 16 comma separated
10319 values in the 1\-255 range.
10322 .B cqm4ic=<list> (also see cqm)
10323 Custom 4x4 intra chrominance matrix, given as a list of 16 comma
10324 separated values in the 1\-255 range.
10327 .B cqm4py=<list> (also see cqm)
10328 Custom 4x4 inter luminance matrix, given as a list of 16 comma separated
10329 values in the 1\-255 range.
10332 .B cqm4pc=<list> (also see cqm)
10333 Custom 4x4 inter chrominance matrix, given as a list of 16 comma
10334 separated values in the 1\-255 range.
10337 .B cqm8iy=<list> (also see cqm)
10338 Custom 8x8 intra luminance matrix, given as a list of 64 comma separated
10339 values in the 1\-255 range.
10342 .B cqm8py=<list> (also see cqm)
10343 Custom 8x8 inter luminance matrix, given as a list of 64 comma separated
10344 values in the 1\-255 range.
10347 .B level_idc=<10\-51>
10348 Set the bitstream's level as defined by annex A of the H.264 standard
10349 (default: 51 \- level 5.1).
10350 This is used for telling the decoder what capabilities it needs to support.
10351 Use this parameter only if you know what it means,
10352 and you have a need to set it.
10356 Spawn threads to encode in parallel on multiple CPUs (default: 1).
10357 This has a slight penalty to compression quality.
10358 0 or 'auto' tells x264 to detect how many CPUs you have and pick an
10359 appropriate number of threads.
10362 .B (no)global_header
10363 Causes SPS and PPS to appear only once, at the beginning of the bitstream
10364 (default: disabled).
10365 Some players, such as the Sony PSP, require the use of this option.
10366 The default behavior causes SPS and PPS to repeat prior to each IDR frame.
10370 Treat the video content as interlaced.
10374 Adjust the amount of logging info printed to the screen.
10384 PSNR and other analysis statistics when the encode finishes (default)
10386 PSNR, QP, frametype, size, and other statistics for every frame
10392 Print signal-to-noise ratio statistics.
10395 The 'Y', 'U', 'V', and 'Avg' PSNR fields in the summary are not
10396 mathematically sound (they are simply the average of per-frame PSNRs).
10397 They are kept only for comparison to the JM reference codec.
10398 For all other purposes, please use either the 'Global' PSNR, or the per-frame
10399 PSNRs printed by log=3.
10403 Print the Structural Similarity Metric results.
10404 This is an alternative to PSNR, and may be better correlated with the
10405 perceived quality of the compressed video.
10409 Enable x264 visualizations during encoding.
10410 If the x264 on your system supports it, a new window will be opened during
10411 the encoding process, in which x264 will attempt to present an overview of
10412 how each frame gets encoded.
10413 Each block type on the visualized movie will be colored as follows:
10427 This feature can be considered experimental and subject to change.
10428 In particular, it depends on x264 being compiled with visualizations enabled.
10429 Note that as of writing this, x264 pauses after encoding and visualizing
10430 each frame, waiting for the user to press a key, at which point the next
10431 frame will be encoded.
10435 .SS xvfw (\-xvfwopts)
10437 Encoding with Video for Windows codecs is mostly obsolete unless you wish
10438 to encode to some obscure fringe codec.
10442 The name of the binary codec file with which to encode.
10446 The name of the codec settings file (like firstpass.mcf) created by vfw2menc.
10449 .SS MPEG muxer (\-mpegopts)
10451 The MPEG muxer can generate 5 types of streams, each of which has reasonable
10452 default parameters that the user can override.
10453 Generally, when generating MPEG files, it is advisable to disable
10454 MEncoder's frame-skip code (see \-noskip, \-mc as well as the
10455 harddup and softskip video filters).
10460 .IPs format=mpeg2:tsaf:vbitrate=8000
10465 .B format=<mpeg1 | mpeg2 | xvcd | xsvcd | dvd | pes1 | pes2>
10466 stream format (default: mpeg2).
10467 pes1 and pes2 are very broken formats (no pack header and no padding),
10468 but VDR uses them; do not choose them unless you know exactly what you
10472 .B size=<up to 65535>
10473 Pack size in bytes, do not change unless you know exactly what
10474 you are doing (default: 2048).
10478 Nominal muxrate in kbit/s used in the pack headers (default: 1800 kb/s).
10479 Will be updated as necessary in the case of 'format=mpeg1' or 'mpeg2'.
10483 Sets timestamps on all frames, if possible; recommended when format=dvd.
10484 If dvdauthor complains with a message like "..audio sector out of range...",
10485 you probably did not enable this option.
10489 Uses a better algorithm to interleave audio and video packets, based on the
10490 principle that the muxer will always try to fill the stream with the largest
10491 percentage of free space.
10494 .B vdelay=<1\-32760>
10495 Initial video delay time, in milliseconds (default: 0),
10496 use it if you want to delay video with respect to audio.
10497 It doesn't work with :drop.
10500 .B adelay=<1\-32760>
10501 Initial audio delay time, in milliseconds (default: 0),
10502 use it if you want to delay audio with respect to video.
10506 When used with vdelay the muxer drops the part of audio that was
10510 .B vwidth, vheight=<1\-4095>
10511 Set the video width and height when video is MPEG-1/2.
10514 .B vpswidth, vpsheight=<1\-4095>
10515 Set pan and scan video width and height when video is MPEG-2.
10518 .B vaspect=<1 | 4/3 | 16/9 | 221/100>
10519 Sets the display aspect ratio for MPEG-2 video.
10520 Do not use it on MPEG-1 or the resulting aspect ratio will be completely wrong.
10524 Sets the video bitrate in kbit/s for MPEG-1/2 video.
10527 .B vframerate=<24000/1001 | 24 | 25 | 30000/1001 | 30 | 50 | 60000/1001 | 60 >
10528 Sets the framerate for MPEG-1/2 video.
10529 This option will be ignored if used with the telecine option.
10533 Enables 3:2 pulldown soft telecine mode: The muxer will make the
10534 video stream look like it was encoded at 30000/1001 fps.
10535 It only works with MPEG-2 video when the output framerate is
10536 24000/1001 fps, convert it with \-ofps if necessary.
10537 Any other framerate is incompatible with this option.
10541 Enables FILM to PAL and NTSC to PAL soft telecine mode: The muxer
10542 will make the video stream look like it was encoded at 25 fps.
10543 It only works with MPEG-2 video when the output framerate is
10544 24000/1001 fps, convert it with \-ofps if necessary.
10545 Any other framerate is incompatible with this option.
10548 .B tele_src and tele_dest
10549 Enables arbitrary telecining using Donand Graft's DGPulldown code.
10550 You need to specify the original and the desired framerate; the
10551 muxer will make the video stream look like it was encoded at
10552 the desired framerate.
10553 It only works with MPEG-2 video when the input framerate is smaller
10554 than the output framerate and the framerate increase is <= 1.5.
10561 .IPs tele_src=25,tele_dest=30000/1001
10562 PAL to NTSC telecining
10567 .B vbuf_size=<40\-1194>
10568 Sets the size of the video decoder's buffer, expressed in kilobytes.
10569 Specify it only if the bitrate of the video stream is too high for
10570 the chosen format and if you know perfectly well what you are doing.
10571 A too high value may lead to an unplayable movie, depending on the player's
10573 When muxing HDTV video a value of 400 should suffice.
10576 .B abuf_size=<4\-64>
10577 Sets the size of the audio decoder's buffer, expressed in kilobytes.
10578 The same principle as for vbuf_size applies.

10626 and the decoding timestamp (DTS) for any stream present
10627 (demux to decode delay).
10628 Default is 0.7 (as mandated by the standards defined by MPEG).
10629 Higher values require larger buffers and must not be used.

10709 .SH ENVIRONMENT VARIABLES
10711 There are a number of environment variables that can be used to
10712 control the behavior of MPlayer and MEncoder.
10715 .B MPLAYER_CHARSET (also see \-msgcharset)
10716 Convert console messages to the specified charset (default: autodetect).
10717 A value of "noconv" means no conversion.
10721 Directory where MPlayer looks for user settings.
10724 .B MPLAYER_VERBOSE (also see \-v and \-msglevel)
10725 Set the initial verbosity level across all message modules (default: 0).
10726 The resulting verbosity corresponds to that of \-msglevel 5 plus the
10727 value of MPLAYER_VERBOSE.
10733 If LADSPA_PATH is set, it searches for the specified file.
10734 If it is not set, you must supply a fully specified pathname.
10735 FIXME: This is also mentioned in the ladspa section.
10741 Specify a directory in which to store title key values.
10742 This will speed up descrambling of DVDs which are in the cache.
10743 The DVDCSS_CACHE directory is created if it does not exist,
10744 and a subdirectory is created named after the DVD's title
10745 or manufacturing date.
10746 If DVDCSS_CACHE is not set or is empty, libdvdcss will use
10747 the default value which is "${HOME}/.dvdcss/" under Unix and
10748 "C:\\Documents and Settings\\$USER\\Application Data\\dvdcss\\" under Win32.
10749 The special value "off" disables caching.
10753 Sets the authentication and decryption method that
10754 libdvdcss will use to read scrambled discs.
10755 Can be one of title, key or disc.
10759 is the default method.
10760 libdvdcss will use a set of calculated player keys to try and get the disc key.
10761 This can fail if the drive does not recognize any of the player keys.
10763 is a fallback method when key has failed.
10764 Instead of using player keys, libdvdcss will crack the disc key using
10765 a brute force algorithm.
10766 This process is CPU intensive and requires 64 MB of memory to store
10769 is the fallback when all other methods have failed.
10770 It does not rely on a key exchange with the DVD drive, but rather uses
10771 a crypto attack to guess the title key.
10772 On rare cases this may fail because there is not enough encrypted data
10773 on the disc to perform a statistical attack, but in the other hand it
10774 is the only way to decrypt a DVD stored on a hard disc, or a DVD with
10775 the wrong region on an RPC2 drive.
10780 .B DVDCSS_RAW_DEVICE
10781 Specify the raw device to use.
10782 Exact usage will depend on your operating system, the Linux
10783 utility to set up raw devices is raw(8) for instance.
10784 Please note that on most operating systems, using a raw device
10785 requires highly aligned buffers: Linux requires a 2048 bytes
10786 alignment (which is the size of a DVD sector).
10790 Sets the libdvdcss verbosity level.
10794 Outputs no messages at all.
10796 Outputs error messages to stderr.
10798 Outputs error messages and debug messages to stderr.
10804 Skip retrieving all keys on startup.
10805 Currently disabled.
10809 FIXME: Document this.
10814 .B AO_SUN_DISABLE_SAMPLE_TIMING
10815 FIXME: Document this.
10819 FIXME: Document this.
10823 Specifies the Network Audio System server to which the
10824 nas audio output driver should connect and the transport
10825 that should be used.
10826 If unset DISPLAY is used instead.
10827 The transport can be one of tcp and unix.
10828 Syntax is tcp/<somehost>:<someport>, <somehost>:<instancenumber>
10829 or [unix]:<instancenumber>.
10830 The NAS base port is 8000 and <instancenumber> is added to that.
10837 .IPs AUDIOSERVER=somehost:0
10838 Connect to NAS server on somehost using default port and transport.
10839 .IPs AUDIOSERVER=tcp/somehost:8000
10840 Connect to NAS server on somehost listening on TCP port 8000.
10841 .IPs AUDIOSERVER=(unix)?:0
10842 Connect to NAS server instance 0 on localhost using unix domain sockets.
