Rendering hang with transitions
Last modified: 2011-05-22 23:02:26 UTC
Hi, Using pitivi Git HEAD (fad58f95e..) I'm seeing a rendering hang at exactly the point where rendering reaches the first transition. I'm attaching a "GST_DEBUG=3,gnl*:5,python:5 PITIVI_DEBUG=5" debug log, but as far all it shows is the timeline staying in the same place rather than advancing. Happy to help try to debug farther, let me know what other information I should provide. Thanks.
The attachment is too big. It's here: http://chris.printf.net/pitivi-transitions-log.bz2
This is 100% reproducible (at least with the particular movies I'm using) and happens on Ubuntu Lucid as well as Fedora Rawhide.
By making the transition very long, I see that the hang happens at the very end (perhaps even past the very end) of the transition, maybe where the first non-transition frame from the clip being transitioned to is being rendered.
Marking as blocker for 0.13.5 . Hopefully this can be fixed solely in pitivi/gnonlin :(
Rendering also hangs with still images. This is even more basic than transitions
I've noticed this to some degree with every transition, and when there are many of them it can come close to unusable.
