[MPlayer-users] Controlling audio filter from slave mode?

[Remo Inverardi]

Hello.

I'm planing to use MPlayer for playing audio and video files on my car 
multimedia system. The whole system is controlled using a touchscreen 
and custom C++ software, so I need a way to control MPlayer using my own 
code.

After playing around a bit, I discovered MPlayer's slave mode, which 
satisfies almost all of my requirements (pause, seek, quit, etc). The 
only exceptions is the audio equalizer: controlling it using the command 
line ("mplayer -af equalizer=...") works great, but I was unable to find 
a way to control the equalizer while MPlayer is running.

Is there a slave command that I missed? Is there a better way to control 
the audio equalizer from my frontend? And if everything else fails: is 
it possible to use MPlayer as a library (I used to play around with 
libxine and loved it, but well, of *course* MPlayer's better <g>).

Thanks, Remo
