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.
35 Available commands ('mplayer -input cmdlist' will print a list):

209 Pause/unpause the playback.
212 Play one frame, then pause again.
214 pt_step <value> [force]
215 Go to the next/previous entry in the playtree. The sign of <value> tells

290 Loads subtitles from <subtitle_file>.
293 Logs the current or last displayed subtitle together with filename

295 is to allow convenient marking of bogus subtitles which need to be
296 fixed while watching the movie.
298 sub_pos <value> [abs]
299 Adjust/set subtitle position.
302 If the [value] argument is present and non-negative, removes the subtitle
303 file with index [value]. If the argument is omitted or negative, removes
307 Display subtitle with index [value]. Turn subtitle display off if
308 [value] is -1 or greater than the highest available subtitle index.
309 Cycle through the available subtitles if [value] is omitted or less
310 than -1. Supported subtitle sources are -sub options on the command
311 line, VOBsubs, DVD subtitles, and Ogg and Matroska text streams.
312 This command is mainly for cycling all subtitles, if you want to set
313 a specific subtitle, use sub_file, sub_vob, or sub_demux.
316 Display first subtitle from [source]. Here [source] is an integer:
317 SUB_SOURCE_SUBS (0) for file subs

327 will cycle all file subs.
330 Display subtitle specifid by [value] for vobsubs. The [value] is
331 corresponding to ID_VOBSUB_ID values reported by '-identify'.
332 If [value] is -1, will turn off subtitle display. If [value] less than -1,
333 will cycle all vobsubs.
336 Display subtitle specifid by [value] for subtitles from DVD or embedded
337 in media file. The [value] is corresponding to ID_SUBTITLE_ID values
338 reported by '-identify'. If [value] is -1, will turn off subtitle display.
339 If [value] less than -1, will cycle all DVD subs or embedded subs.
341 sub_scale <value> [abs]
342 Adjust the subtitle size by +/- <value> or set it to <value> when [abs]
346 This is a stub linked to sub_select for backwards compatibility.

369 There might be problems with some video filters.
371 switch_title [value] (DVDNAV only)
372 Switch to the DVD title with the ID [value]. Cycle through the
373 available titles if [value] is omitted or negative.

377 vsync status is inverted.
379 teletext_add_digit <value>
380 Enter/leave teletext page number editing mode and append given digit to
381 previously entered one.
382 0..9 - Append apropriate digit. (Enables editing mode if called from normal
383 mode, and switches to normal mode when third digit is entered.)
384 - - Delete last digit from page number. (Backspace emulation, works only
385 in page number editing mode.)

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

462 are through the video output driver.
