[CRASH] During watch recording

Reported by: Dave Badia <dbadia@…> Owned by:

Component: MythTV - General Version: 0.24-fixes
Severity: medium Keywords:
Cc: Ticket locked: no


I'm trying to do some development work on a new laptop, and am running 24.1 fixes on ubuntu 11.10. When I try to watch a recording, audio plays for a split second then the frontend segfaults. I've got CPU+ configured for video and pulse for audio.

This backtrace is from 24.1 fixes, but I tried with master and the backtrace looks similar

This looks like a crash in your graphics driver to me, but I'll leave it to people more familiar with video playback to comment.

From the backtrace, I'm guessing this is the same problem described in (and ultimately fixed in):-

Do you get any error messages on the command line about failed attempts to make the OpenGL context current? or similar?

Yes, that url discusses the same issue. Not sure I missed that on the mailing list. Switching to xv fixes the problem so this is a duplicate of the known driver issue.

Seems to be a bug in Mesa, as described in the thread markk linked in comment:2.
