4 The -slave option switches on slave mode, in which MPlayer works as a backend
5 for other programs. Instead of intercepting keyboard events, MPlayer will read
6 commands separated by a newline (\n) from stdin.
8 To try slave mode out by hand, run
10 mplayer -slave -quiet <movie>
12 and type slave commands into the console window.
14 You can also use a fifo file (named pipe):
16 mkfifo </tmp/fifofile>
17 mplayer -slave -input file=</tmp/fifofile> <movie>
19 Most slave mode commands are equivalent to command line options, though not
20 necessarily under the same name. Detailed descriptions can be found in the
23 All commands can be prefixed with one of "pausing ", "pausing_keep ", or
24 "pausing_toggle ". "pausing " tells MPlayer to pause as soon as possible
25 after processing the command. "pausing_keep " tells MPlayer to do so only if
26 it was already in paused mode. "pausing_toggle " tells MPlayer to do so
27 only if it was not already in paused mode. Please note that "as soon as
28 possible" can be before the command is fully executed.
29 As a temporary hack, there is also the _experimental_ "pausing_keep_force "
30 prefix, with which MPlayer will not exit the pause loop at all.
31 Like this you can avoid the "frame stepping" effect of "pausing_keep "
32 but most commands will either not work at all or behave in unexpected ways.
33 For "set_mouse_pos" and "key_down_event", "pausing_keep_force" is the default
34 since other values do not make much sense for them.
37 Various tips and tricks (please help expand it!):
39 - Try using something like
40 pausing_keep_force pt_step 1
42 to switch to the next file. It avoids audio playback starting to play
43 the old file for a short time before switching to the new one.
44 - To ensure the user can't control MPlayer "behind your back" use
45 something like -input nodefault-bindings -noconfig all

249 pt_step <value> [force]
250 Go to the next/previous entry in the playtree. The sign of <value> tells

278 type = 1 is a seek to <value> % in the movie.
279 type = 2 is a seek to an absolute position of <value> seconds.
280 The hr-seek parameter controls whether to use precise seeks (not limited

286 seek_chapter <value> [type]
287 Seek to the start of a chapter.
288 0 is a relative seek of +/- <value> chapters (default).

304 manner defined for that property (if any).

337 sub_load <subtitle_file>
338 Loads subtitles from <subtitle_file>.
341 Logs the current or last displayed subtitle together with filename
342 and time information to ~/.mplayer/subtitle_log. Intended purpose
343 is to allow convenient marking of bogus subtitles which need to be
344 fixed while watching the movie.
346 sub_pos <value> [abs]
347 Adjust/set subtitle position.
350 If the [value] argument is present and non-negative, removes the subtitle

355 Display subtitle with index [value]. Turn subtitle display off if
356 [value] is -1 or greater than the highest available subtitle index.
357 Cycle through the available subtitles if [value] is omitted or less
358 than -1. Supported subtitle sources are -sub options on the command
359 line, VOBsubs, DVD subtitles, and Ogg and Matroska text streams.
360 This command is mainly for cycling all subtitles, if you want to set
361 a specific subtitle, use sub_file, sub_vob, or sub_demux.
364 Display first subtitle from [source]. Here [source] is an integer:
365 SUB_SOURCE_SUBS (0) for file subs
366 SUB_SOURCE_VOBSUB (1) for VOBsub files
367 SUB_SOURCE_DEMUX (2) for subtitle embedded in the media file or DVD subs.
368 If [source] is -1, will turn off subtitle display. If [source] less than -1,
369 will cycle between the first subtitle of each currently available sources.
372 Display subtitle specifid by [value] for file subs. The [value] is
373 corresponding to ID_FILE_SUB_ID values reported by '-identify'.
374 If [value] is -1, will turn off subtitle display. If [value] less than -1,
375 will cycle all file subs.
378 Display subtitle specifid by [value] for vobsubs. The [value] is
379 corresponding to ID_VOBSUB_ID values reported by '-identify'.
380 If [value] is -1, will turn off subtitle display. If [value] less than -1,
381 will cycle all vobsubs.
384 Display subtitle specifid by [value] for subtitles from DVD or embedded
385 in media file. The [value] is corresponding to ID_SUBTITLE_ID values
386 reported by '-identify'. If [value] is -1, will turn off subtitle display.
387 If [value] less than -1, will cycle all DVD subs or embedded subs.
389 sub_scale <value> [abs]
390 Adjust the subtitle size by +/- <value> or set it to <value> when [abs]
394 This is a stub linked to sub_select for backwards compatibility.
397 Step forward in the subtitle list by <value> steps or backwards if <value>
400 sub_visibility [value]
401 Toggle/set subtitle visibility.
403 forced_subs_only [value]
404 Toggle/set forced subtitles only.
406 switch_audio [value] (currently MPEG*, AVI, Matroska and streams handled by libavformat)

408 available tracks if [value] is omitted or negative.
410 switch_angle [value] (DVDs only)
411 Switch to the DVD angle with the ID [value]. Cycle through the
412 available angles if [value] is omitted or negative.
415 Change aspect ratio at runtime. [value] is the new aspect ratio expressed
416 as a float (e.g. 1.77778 for 16/9).
417 There might be problems with some video filters.
419 switch_title [value] (DVDNAV only)
420 Switch to the DVD title with the ID [value]. Cycle through the
421 available titles if [value] is omitted or negative.
424 Toggle vsync (1 == on, 0 == off). If [value] is not provided,
425 vsync status is inverted.
427 teletext_add_digit <value>
428 Enter/leave teletext page number editing mode and append given digit to
429 previously entered one.
430 0..9 - Append apropriate digit. (Enables editing mode if called from normal
431 mode, and switches to normal mode when third digit is entered.)

496 The following commands are really only useful for OSD menu console mode:
499 Displays help text, currently empty.
502 Exits from OSD menu console. Unlike 'quit', does not quit MPlayer.
505 Hides the OSD menu console. Clicking a menu command unhides it. Other
506 keybindings act as usual.
