#2471 closed defect (fixed)

mythtv playback messed up after cutpoint

Reported by: darkstarsword@… Owned by: Isaac Richards
Priority: minor Milestone: unknown
Component: mythtv Version: 0.20
Severity: medium Keywords:
Cc: Ticket locked: no


One of the programs I recorded from DTV-T recently will not play back correctly in MythTV after it passes certain comercial breaks that I cut out - always the same ones, but not all of them. To get it to play normally I have to hit escape to go back to the menu and then play it from where I left, or hit skip forward as it approaches the cut. MPlayer plays the same video fine without any issues.

This is the procedure that I used (nothing special I can think of): Record stream from DTV-T Usually it is set to automatically flag commercials and then transcode into MPEG4, but this time I deleted those jobs before they started Set cutpoints Queue job to transcode using default profile (only difference from defaults on installation is set to encode video in MPEG4)

So far this has affected two recordings since I upgraded to MythTV 0.20 - If memory serves the first time I let it auto transcode and added the cutlist and retranscoded losslessly afterwards. I never experienced this in 0.19, but I haven't downgraded to find out if the player in the old version is also affected.

I have cut out a few seconds of video from around one of the affected breaks and attached it.

You can get the video from:

Also, I forgot to mention just how the playback is messed up. The video is played way too fast, but only a few frames are actually displayed, and after a few seconds the audio begins to jump when the buffer runs out. Just when the cut is played, "NVP: prebuffering pause" is repeatedly displayed on the console and just before the audio messes up "NVP::AddAudioData?():p3: Audio buffer overflow, audio data lost!" joins it, both of which continue to be repeated.

Resolution: fixed
Status: newclosed

(In [11324]) Disable the automatic bits of WrapTimecode?. If this causes any problems, I will need sample videos.

Fixes #2471, #2355, possibly others..

Thanks, it seems to be working now.
