I have a source file that has 12 channels of mono audio. There are 4 audio
programs contained on those channels. I am creating a QuickTime proxy that
represents the 4 audio programs. I was hoping to do this all in one pass,
but due to limitations in ffmpeg, I have to first extract the audio
programs as WAV and then call them as sources. The issue is for the first
two stereo programs, the audio channels are offset and you hear an echo.
The second issue is the 5.1 mix comes out as silence and the last stereo
mix comes out as silence as well. I tested this with a pre-compiled
version of 2.2.2 and I also downloaded a snapshot which I compiled.

If all the WAV files would extract properly, I then would execute the
following to create a proxy from the sources. Wish FFMPEG would just merge
all the input channels, and then you could specify which channels to take.
