This file crashes my rhythmbox, and also totem:

Comment 1 Wim Taymans 2006-03-22 12:36:31 UTC

rmdemux does not pass extradata to the decoder, this makes negotiation fail. A patch to gst-ffmpeg was commited to fix a deadlock we triggered in this case.

After this error, playbin starts _unreffing some elements instead of unparenting them which causes a series of other random errors.

Comment 2 Tim-Philipp Müller 2006-03-22 12:56:45 UTC

There's a patch for the extradata stuff in the patch in bug #323023. Couldn't test it properly yet - will try with this file.

Comment 3 Wim Taymans 2006-03-22 18:40:52 UTC

mentioned patch crashes my totem, lots of ffmpeg errors, backtrace is borked and useless...

Added some checks to core to catch the unreffing of objects that still have a parent which does not cause core to make things worse.

Comment 5 Wim Taymans 2006-08-16 10:58:56 UTC

it seems there is only a problem with the video part. rmdemux/Fluendo real video decoder/ffmpeg cook has no problem with this video, rmdemux/ffmpeg video/ffmpeg cook crashes the video decoder.

Comment 8 Sebastian Dröge (slomo) 2006-12-20 16:50:33 UTC

If someone wants a backtrace and sample file... http://iceman-srv.be/Daria%20-%20407%20-%20Of%20Human%20Bonding.rm

and then running gnome-video-thumbnailer -s 128  on it. This is with the latest (pre) releases of everything.
