But that requires audio integration in ffmpeg.

Which patches are we missing for that?
I suppose they are:

* resample filter
* auto resampling insertion
* anull, anullsrc and anullsink (not strictly required but help testing/debugging)
* asrcbuffer
* aformat/anoformat
* ffmpeg and ffplay integration

Regards.
