Comment (by Lawrence Rust <lvr@…>):
Further investigation indicates that the audio data are correctly
formatted with AC3 - I used an mp4 video with AC3 audio produced with
ffmpeg. However, it appears that the timecodes for audio are unreliable
such that when you seek back and forth you get different audio data for
the same location. Maybe this is a consequence of a bad or missing
posmap?
I couldn't get mythcommflag to rebuild the posmap for my mp4 video. It
appears that avformatdecoder doesn't understand framing in H264 NAL
streams, only annexe B.
