Seek problems with Handbrake 0.9.5 produced m4v files
|Reported by:||Jason Gillis <gillisj@…>||Owned by:||tralph|
|Component:||MythTV - Video Playback||Version:||0.24-fixes|
I've been noticing that myth has recently started to have problems with seeking in m4v files produced by Handbrake (I'm using 0.9.5 for OSX currently, happens with a recent nightly build of Handbrake, also). This was raised on the users list here: http://www.gossamer-threads.com/lists/mythtv/users/501998
The basic symptoms are that playback appears fine, without any A/V sync issues and no noticeable problems until seeking occurs (usually in response to "What did he say?"). When seeking back, myth skips back to much earlier in the m4v file than expected with a 5 second skip back. It can be as much as 10 minutes.
I've noticed that the current time position display in the OSD seems to advance more slowly than real-time. When skipping back, myth seems to correctly skip back to 5 seconds before what it thinks is the current time position in the file. In the attached file, I skipped back right before the end of the log file. Myth had been playing for about 52 minutes. Just prior to skipping back, the time display on the OSD noted 39 minutes and some seconds. Skipping back went back to the correct position for that time in the file, so the amount skipped back was in excess of 10 minutes.
Re-encoding the source DVD to MKV format using handbrake yields a file that does not show this problem. Choosing different encoding options in Handbrake for m4v output don't change the incorrect seek behavior.
Attached are output of the myth version, a log file produced using -v playback,timestamp,extra (per request from Taylor Ralph) and the video info for the file (both mythffmpeg and mediainfo).
Please let me know what additional information I can provide.
