Description Joseph Sacco 2006-03-11 16:22:18 UTC
System: linuxPPC running YDL-4.1 [FC4 clone, gcc-3.4.4]

The typefind plugin fails to load when running any of the gst-* tools. For example,

% gst-inspect-0.10

ERROR: Caught a segmentation fault while loading plugin file:

Please either:
- remove it and restart.
- run with --gst-disable-segtrap and debug.

Replacing only, with its predecessor from version 0.10.3 eliminates the problem.

For what it's worth, this problem appears to be linuxPPC specific. The version 0.10.4 plugin loads without incident on a lintel box.

Comment 1 Tim-Philipp Müller 2006-03-11 16:38:55 UTC
Could you do this then:

 % gdb --args gst-inspect-0.10 --gst-disable-segtrap
 Welcome to the GNU debugger...
 (gdb) run
  .... wait for segfault ...
 (gdb) thread apply all bt

and paste all the output?

Thanks for the stack trace. I think this patch should fix it. If not, please re-open. We should probably be doing a 0.10.5 release really soon ...

        * gst/typefind/gsttypefindfunctions.c: (plugin_init):
          NULL-terminate array of mpeg4 video file extensions.
          Fixes crash on PPC (#334226).

Comment 5 Joseph Sacco 2006-03-11 19:57:57 UTC

That patch seems to work.
