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

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>"
|
||
|
|
|
||
|
|
|
||
|
|
Available properties:
|
||
|
|
|
||
|
|
name type min max get set step comment
