I agree that on the technical side it doesn't bring new features nor
performance improvements. It's all about avoiding licensing/patents
issues with AAC and AMR here.
In this specific case we already have the wrapper infrastructure, the
audio part only needs small adjustments to work.
Moreover, if that helps, I can reduce the scope of the patch to AAC
and AMR only and get rid of mp3/flac/vorbis/opus support. What do you
think ?
