Re: [Bf-committers] AAC and ACC3 support
David, I've commited your patch. At least it can not make AAC/AC3 worse :) Also seems the same change was needed for Vorbis with FFmpeg-1.0.

[Bf-committers] AAC and ACC3 support
Hi Sergey As as I know there are no ways to have aac sound in ffmpeg in GPL compatible way --enable-libfdk-aac is also incompatible with GPL. as to what to make with such situation - it is up to developers.
