Hi Amon, these are actually good questions for the ffmpeg-user mailing list. (ffmpeg-devel is for discussion about the actual development of ffmpeg.)

So you specifically mean MPEG-2 Part 3? With a quick search, I couldn't find any open source encoder for that. (ffmpeg has a native MPEG layer II encoder, as well as support for the toolame and twolame libraries.) > i also wondered what would happen if ffmpeg had actual encoding > support for MPEG-1 Audio Layer I. What would happen? I guess nobody would use it. Is there any practical use? AFAICT only Digital Compact Cassette made use of it?
