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

af_add <filter_arguments_list> (comma separated list of audio filters with parameters)
(experimental) Load the given list of audio filters.
af_clr

is to allow convenient marking of bogus subtitles which need to be
fixed while watching the movie.
sub_pos <value> [abs]

sub_remove [value]
If the [value] argument is present and non-negative, removes the subtitle
file with index [value]. If the argument is omitted or negative, removes
all subtitle files.
sub_select [value]
Display subtitle with index [value]. Turn subtitle display off if
[value] is -1 or greater than the highest available subtitle index.
Cycle through the available subtitles if [value] is omitted or less
than -1 (forward or backward respectively).
Supported subtitle sources are -sub options on the command
line, VOBsubs, DVD subtitles, and Ogg and Matroska text streams.
This command is mainly for cycling all subtitles, if you want to set
a specific subtitle, use sub_file, sub_vob, or sub_demux.
sub_source [source]
Display first subtitle from [source]. Here [source] is an integer:
SUB_SOURCE_SUBS (0) for file subs
SUB_SOURCE_VOBSUB (1) for VOBsub files
SUB_SOURCE_DEMUX (2) for subtitle embedded in the media file or DVD subs.
If [source] is -1, will turn off subtitle display.
If [value] is omitted or less than -1, will cycle between the first subtitle
of each currently available source (forward or backward respectively).
sub_file [value]
Display subtitle specified by [value] for file subs. The [value] is
corresponding to ID_FILE_SUB_ID values reported by '-identify'.
If [value] is -1, will turn off subtitle display.
If [value] is omitted or less than -1, will cycle all file subs
(forward or backward respectively).
sub_vob [value]

corresponding to ID_VOBSUB_ID values reported by '-identify'.
If [value] is -1, will turn off subtitle display.
If [value] is omitted or less than -1, will cycle all VOBsubs
(forward or backward respectively).
sub_demux [value]
Display subtitle specified by [value] for subtitles from DVD or embedded
in media file. The [value] is corresponding to ID_SUBTITLE_ID values
reported by '-identify'. If [value] is -1, will turn off subtitle display.
If [value] is omitted or less than -1, will cycle all DVD subs or embedded subs
(forward or backward respectively).
sub_scale <value> [abs]
Adjust the subtitle size by +/- <value> or set it to <value> when [abs]
is nonzero.
vobsub_lang
This is a stub linked to sub_select for backwards compatibility.

is negative.

Toggle/set subtitle visibility.
forced_subs_only [value]

switch_angle [value] (DVDs only)
Switch to the DVD angle with the ID [value]. Cycle through the
available angles if [value] is omitted or negative.
switch_ratio [value]
Change aspect ratio at runtime. [value] is the new aspect ratio expressed
as a float (e.g. 1.77778 for 16/9), or special value -1 to reset to
original aspect ratio (ditto if [value] is missing), or special value 0
to disable automatic movie aspect ratio compensation.
There might be problems with some video filters.
switch_title [value] (DVDNAV only)
Switch to the DVD title with the ID [value]. Cycle through the
available titles if [value] is omitted or negative.
switch_vsync [value]
Toggle vsync (1 == on, 0 == off). If [value] is not provided,
vsync status is inverted.
teletext_add_digit <value>
Enter/leave teletext page number editing mode and append given digit to
previously entered one.
0..9 - Append appropriate digit. (Enables editing mode if called from normal
mode, and switches to normal mode when third digit is entered.)
- - Delete last digit from page number. (Backspace emulation, works only
in page number editing mode.)

The following commands are really only useful for OSD menu console mode:
help
Displays help text, currently empty.
exit
Exits from OSD menu console. Unlike 'quit', does not quit MPlayer.
hide
Hides the OSD menu console. Clicking a menu command unhides it. Other
keybindings act as usual.
run <string>
Run <string> with properties expanded as shell command. In OSD menu
console mode stdout and stdin are through the video output driver.
Property expansion happens in the same way as for osd_show_property_text.
Note: MPlayer will do property expansion on anything of the form
${somevar} before it is passed to the shell.
This means that you cannot use this syntax for anything you actually
want the shell to handle, though any other form like $somevar will
be passed on to and processed by the shell.
Example:
run "echo ${filename} ${stream_pos} >> <path_to_file>"

name type min max get set step comment
