[MPlayer-users] auto-select alsa-output plugin according to decodec channels?

[Markus Schulz]

Hello,

is there any way that mplayer selects automaticly surround51 for 6
channel data without need to specify "-channels 6 -af channels=6"?

Reason is: if you use the alsa on-the-fly ac3 encoder plugin, there are
some problems if you play stereo files with -channels 6 and -af
channels=6 option with mplayer. Mplayer reports sometimes "System to
slow" (false report) and loss the sync of video/audio.

It would be nice if mplayer follows this way:
- decoder reports 2 channels
-> select alsa:device=default

- decoder reports 4 channels
-> select alsa:device=surround40

- decoder reports 6 channels
-> selec alsa:device=surround51

and so on.

It this currently possible or perhaps doable as a future enhancement?

Currently i must start with -v to see how many channels the file has
 and restart with correct parameters. This is poor scriptable and time
 consuming.
