Lav audio codec / channel control

[GoogleCodeExporter]

Describe the issue you're having:

Lav audio codec would be able to set the level of each channels involved by the 
audio chain. even mute them. Also through Api.

What version of the product are you using? In which Player?

0.48 

Please provide any additional information below.

I'm developing an application in Delphi for subtitling purpose. For example I'm 
interested to keep center channel, when avaiable, and mute the others one.

The only thing you'll get is a matrix mixer to play with.
In theory you can use that to mute channels and change their volume.

Track issue 11.

It's not the same thing because I use a filter graph to extract a peak file or 
a wav file from the original audio stream. I should find a directX filter with 
Api interface to handle it.

That is all i will offer, because it offers a lot of flexibility.
With such a matrix, you can do a lot to the audio, including muting channels or 
lowering their volume. No need to build a separate function for that feature 
alone.
