GNOME Bugzilla – Bug 688881
[pitivi] [ges] Playhead/seeker jumps ahead and skips clips or ignores streams during playback of consecutive clips
Last modified: 2016-02-21 22:22:21 UTC
This is a continuation of bug #673038 with the remaining symptoms. The fact that the seeker/playhead would jump backwards has been fixed as far as I can tell, but the problem with the seeker jumping forward or skipping sources entirely remains. This issue is easily reproducible with the latest gstreamer 1.x releases. It is certainly not specific to 1.x as bug #673038 was reported back when we were still using the 0.10 series. It is suspected that this bug may have always been there, but we were not experiencing it before the switch to GES because pitivi used to have its own decodebin in python, we were not using gnlurisource. I'll link to some videos that illustrate the issue better than words.
http://jeff.ecchi.ca/public/gstreamer-688881-simple.webm In this case, I just have a couple of clips one after another, and I'm not touching the UI during playback. As you can see, the playhead jumps ahead and skip clips. http://jeff.ecchi.ca/public/gstreamer-688881-multiple-layers.webm In this sample*, the playhead doesn't "jump" ahead, but once the seeker reaches the boundary of a second clip, it simply stops updating the viewer (possibly the pipeline/bus gets broken?). You won't get an image back until you force a seek by clicking the ruler like I did at various points in that video. *: http://jeff.ecchi.ca/public/sample-pitivi-projects/Texture%20(theora).tar
Two years on, what to do with this? Close as OBSOLETE? Have you tested with new ges/nl yet?
