Totem Crashes on Certain .mpg Files

[Lukas Sabota]

When opening certain .mpg files, totem will begin to load but then crash. When launching $totem mediafilename.mpg, this output is displayed on the console:
(totem:12732): GStreamer-CRITICAL **: gst_object_ref: assertion `GST_IS_OBJECT (object)' failed
Segmentation fault

I have gstreamer0.10-bad, gstreamer0.10-good, and gstreamer0.10-ugly installed.

[Sebastien Bacher (seb128)]

Thanks for your bug. I've a .mpg on my disk and totem plays it just fine with the gstreamer0.10-plugins-ugly package installed. Do you have any URL to .mpg producing that bug. If not could you put one somewhere for download (feel free to point it by mail if you don't want to put the URL on the bug tracker)? Media bugs are not easy to fix without having an example exibing the issue

Could you get a backtrace of the crash:
- gdb totem
(gdb) run
... crahs
(gdb) thread apply all bt

and copy that to a comment

Should this bug be put into the needinfo state?

[Daniel Holbach (dholbach)]

Yes, thanks.

[Daniel Holbach (dholbach)]

Could you try with the newest versions and report back? It works nicely for me.

[Claudio André (claudioandre.br)]

Not yet. Totem 1.4.0, GStreamer 0.10.4.

When i try to seek a position, going forward and backwark using the time scrollbar, i receive the error.

[Sebastien Bacher (seb128)]

Thank you for the comment and example, I've forwarded the issue upstream: http://bugzilla.gnome.org/show_bug.cgi?id=335288

[Lukas Sabota (punkrockguy318)]

I can still confirm this on latest dapper

[Antonio Amaro (ajsamaro)]

I've noticed that too.

Totem crashes with .mpg fifes riped with AcidRip maybe cause it uses MPlayer encoding libs (or mencode if you prefer).

Works fine with other .mpg files.

I've not tried yet but I thing it hapens with files encoded with subtitels apart (in other file) an option of AcidRip that may be a good idea if you are going to edit the file with other tools But it seems to bug Totem that doesn't suport subtitels.

(sory the poor english)

Keep the good work!

[Martin Bergner (martin-bergner)]

The bug has been fixed upstream

[Sebastian Dröge (slomo)]

This should be fixed with 0.10.4-0ubuntu1 which was uploaded to edgy some minutes ago.
