buddy buy I can make one (if you want) with gdb.

Have a nice day

Please attach the file or give a link, both are fine. A backtrace would be muych
appreciated. I suspect a segfault in libmpeg2, I've seen that for one file too.

Comment 2 Nicolas Nobelis 2004-04-29 09:23:27 UTC

The video file that make the segv is too big. It cames from
http://www.worldofmi.com/files/fananimations/MURRAY.mpeg, but the worldofmi
server is quit too slow for this big file (8,5mo). If your mail support it, I
can send you the file.

Stack trace is coming.

Good Day
Nicolas

Here come the trace, with gdb :

Unfortunatly, it seems that there was no debugging symbol in the program.

Comment 4 Ronald Bultje 2004-10-01 11:15:20 UTC

Works fine using current CVS of Totem. Your backtrace indicates a broken
registry or a global plugin_init() function somewhere. Updating to latest CVS
(or wait for gst-plugins 0.8.5) should fix that.
