#3943 closed defect (fixed)

Since Changeset 14460, mythtv segfaults whenever I play live TV or recordings.

Cc: Ticket locked: no


Have been succesfully running svn latest revisions for months until 14460 (mythtv-vid merge), on VIA EPIA 10k hardware with cle266 hardware decoding. Since then, every time I try to watch live TV or a recording the system segfaults. Tried several things: clean/distclean recompile (no errors here), tried several video profiles from the new UI (with and without hardware decoding), recompiled with debug enabled but could not see the problem.

The only guidance I can provide is that the segfault occurs when setting up the audio portion of the stream, maybe when opening the mixer.

Backtrace attached - I have the exact same problem on an EPIA SP1300 with the CN400 video. The segfault occurs when trying to watch TV or any recording, so this version is hosed for me. The fault appears to be centred around openGL, which is not available on my system.

I have tried all of the new vid- settings, standard ffmpeg, libmpeg, xvmc, etc with no change.

We're testing changeset [14439] in mythtv-vid, unless there are problems I'll merge it into trunk in a few days.

(In [14477]) Refs #2287. Fixes #1842. Fixes #3943. Fixes #3479. Merges mythtv-vid to svn trunk.

After the merge last week, I applied some patches that were waiting in the queue for mythtv-vid.

  • Fixes some issues with VIA CN400 drivers not displaying 1080i frames.
  • Adds a workaround to for crashes due to bugs in the Intel and VIA OpenGL drivers.
  • Allows OpenGL rendering to work with GLX 1.2 for ATI and Intel cards.
  • Seperates preconfigured zoom and aspect ratio override modes, "W" is still the binding for zoom, and "Ctrl-W" now overrides the aspect ratio specified in a video file.
  • Adds a new OpenGL video renderer output filter from Mark Kendall.
  • Reworks some of the OpenGL video renderer locking for greater stability.
