Looks like you have a bad H.264 recording.

comment:2 Changed 10 years ago by anonymous

When I looked at the backtrace, I also saw the reference to H.264; however, the channel ID is 1061 which, I'm assuming, means it used video source #1 which is SD local broadcast. This video source is tied to either my HVR-1800 or my HD-HR both of which produce mpeg-2 files. So why the reference to H.264 (which to my understanding only applies to my HD-PVR).

This problem surfaced again last night on an NBC program. Backtrace is similar to the one previously attached. As an added point of interest, I rescheduled the the commflag job and it completed normally finding five commercial breaks.

Is this still an issue in 0.24-fixes or master? A lot of code changes have occurred since this was reported, and if it's not repeatable with newer versions of mythtv (and hence ffmpeg libraries, where this is crashing), then we should close this.

Closing this ticket as requested update not received in 4 weeks. If the issue is still happening with 0.24-fixes or current git master, we'll need an updated backtrace and probably a sample of the file.
