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.
|
|
|
|
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.
|
|
|
|
|
|
Available commands ('mplayer -input cmdlist' will print a list):
|
|
|
|
|
|
alt_src_step <value> (ASX playlist only)

|
When more than one source is available it selects the next/previous one.

|
|
|
|
[brightness|contrast|gamma|hue|saturation] <value> [abs]
|
|

|
|
If [abs] is not given or is zero, modifies parameter by <value>.
