pitivi crashes when trims video from a certain point to the end of the movie

[marco.pallotta]

Binary package hint: thoggen

I have a video that I want to split into two ogv files. I use pitivi for this (v0.11.1 in Hardy x86_64).
The first "split" went ok (I deleted the first part of the video with the left trim control, in the timeline window, and then I rendered the project) but the second "split" always bring pitivi into a crash. I tried to delete the second part of the video (with the right trim control) but when I try to "render project" pitivi crashes.
If I launch pitivi from command line I see the following error:

"
('00:00:00.000', '00:05:07.722')

(pitivi:25601): GStreamer-CRITICAL **: gst_caps_get_structure: assertion `GST_IS_CAPS (caps)' failed
Segmentation fault
"

The same thing happens if I use the advanced view function to cut the parts of the video I want to remove.

This bug looks like it needs to be re-assigned to the 'pitivi' package.

Excuse me: I was wrong in selecting the right package affected by the bug.

I launched pitivi with --gst-debug-level=2

I discovered that the problem seems related to the ogg video. In fact with the video "Experience ubuntu.ogg" (default in every installation) I have no issue. This video has:
video codec: theora
framerate: 25 frames per second
audio codec: vorbis - 25050 Hz - 45 kbps

The videos that seem affected by the issue are all made with my video-camera and ripped with thoggen dvdrip. These video have these properties:
video codec: Theora
framerate 25 frames per second
audio codec: vorbis - 44100 Hz - 112 kbps

The strange thing is that the bug is present when I select the right trim control and not the left one.

I have found a similar bug in upstream (gnome-bugs 518689) in needinfo status.

[marco.pallotta (marco-pallotta)]

I want to provide more useful info. The issue happens when I select, as output, the ogg container while with other containers (mov, mpg, avi) I have the error the I posted in attachment.
With the "Experience ubuntu.ogg" all runs ok.

[marco.pallotta (marco-pallotta)]

I trimmed the ogg videos, that brings pitivi in crash, with Open Movie Editor with no problems (obviously I had to codify them with a codec other the theora as Open Movie Editor doesn't support it yet) so these movies, even if aren't good for pitivi in some ways, are splittable.

I tried to:
- recreate the same package from source but the same bug happens
- recompiling the same package from tar.gz but the same bug happens
- recompiling next version (pitivi 0.11.2) but the same bug happens with the errors:
pitivi:19543): GStreamer-CRITICAL **: gst_event_new_new_segment_full: assertion `start <= stop' failed

(pitivi:19543): GStreamer-CRITICAL **: gst_event_new_new_segment_full: assertion `start <= stop' failed

Segmentation fault

I tried to recompile the version 0.11.3 but it requires newer packages than the ones installed in Ubuntu Hardy.

I think the problem is in gstreamer.

[marco.pallotta (marco-pallotta)]

I made another try but this time with an mpeg file. If I right trim the video I have the following output if I launch pitivi from command line with --gst-debug-level=1 and the "Render Project" function seems not to start to record (but no error appears):

The bug seems fixed in Jaunty version (0.11.3)
