Description
An FFMPEG bug occasionally causes the MP2 audio codec to be mis-detected for recordings created by pvr-x50 encoders. The problem exists for trunk and fixes. This results in several issues for users:
- no audio on playback
- preview thumbnails missing since libavformat can not process video correctly
- backend slow/hung due to preview generation stuck in loop
And the backend hanging causes:
- playback failing and resulting in "Video buffering failed too many times" since the backend isn't responding
- frontends losing connection to backend since requests to the backend timeout
I've detailed the problem and provided a patch to the FFMPEG project:
http://roundup.ffmpeg.org/roundup/ffmpeg/issue1149
Hopefully it will get fixed upstream in time for the next ffmpeg re-sync.
I'm also attaching a patch for mythtv to this ticket.
