Strack trace?

Comment 2 Christian Fredrik Kalager Schaller 2009-04-27 21:37:42 UTC

what gdb command do I need to run to run gst-inspect inside gdb?

Comment 4 Jarkko Palviainen 2009-08-17 09:58:16 UTC

I cannot reproduce the crash with Ubuntu Karmic packages (gstreamer0.10-ffmpeg version: 0.10.7-1) or current Git. Is this bug already fixed? Which versions were used in the original report?

By the way, there is another unrelated bug affecting ffenc_mpeg4 in my installation: https://bugs.launchpad.net/ubuntu/+source/gstreamer0.10-ffmpeg/+bug/379325/comments/6. I don't know whether that workaround can affect this bug.

Comment 5 Tim-Philipp Müller 2010-08-05 11:08:21 UTC

Christian, does this still happen?

No idea what causes this, but it looks selinux/linker/compiler/system-related and not GStreamer-related. Does the SELinux log say anything?
