Comment (by tralph):
So the log below definitely shows a timestamp issue right after the audio
decoding errors. The audio timestamp jumps way back in time after the
decoding error. These errors and timestamps are provided by the ffmpeg
demuxer. So it appears that the regression is probably due to the ffmpeg
sync done for 0.25. I'm not sure how this should be handled because it's
really an ffmpeg bug. The first step is to create a small sample that
triggers the issue and then see if the ffmpeg devs might be interested in
looking at it.
