GNOME Bugzilla – Bug 563458
Pitivi a bit buggy in playing back
Last modified: 2009-05-14 14:09:51 UTC
Please describe the problem: Watch this recording: http://dl.getdropbox.com/u/84880/pitivi-forgetting-to-display.ogv You'll see that pitivi does not play back the beginning of the cut video unless I scroll to the end and then scroll back. Steps to reproduce: 1. 2. 3. Actual results: Expected results: Does this happen every time? Other information:
sorry, but the video doesn't exist any more. Would you mind re-uploading it? Without more description it's kinda hard to understand.
Vadim, ping?
Sorry, I didn't attach it the first time because the bugzilla has a limit on attachment filesize (how useful). I tried it now, and I couldn't even get it to play back. The red arrow did not want to appear, and when it finally did, it did not play. Here are the videos: http://drop.io/pitivi_buggy_playback
I'm guessing that the cant_get_it_to_play_back.ogv is the screencast of the bug, and the testing_video.ogv is the file you're using to demonstrate the bug. It seems that the testing_video.ogv will not play back properly in either gstreamer apps such as totem, or other applications such as mplayer. I'm inclined to say that the problem is not in PiTiVi itself, but either in gstreamer or in the application that created the file. It might help us if you can tell us how you created these screen casts, including any specific encoding options you may have used.
Eh? It's playing in totem fine and was importable to pitivi. I've used gtk-recordmydesktop to record both, latest version from http://www.getdeb.net/search.php?keywords=gtk-recordmydesktop
I noticed a lot of visual tearing during playback, and when I tried to seek with totem's slider, totem froze. If the codec you're using doesn't properly handle seeking, then it won't work well with pitivi.
The tearing in the video is fine. Seeking does freeze totem, though I always attributed that to totem being buggy. Is there any other testing videos that are guaranteed to work fine?
Try files from youtube or archive.org, which is what I mainly use. If you're working with .mpg files, make sure the gstreamer-fluendo packages are not installed.
Yes, it seems an ogv from archive.org is playing back fine now. I did buy the codecs from canonical/fluendo but don't work with mpg. This bug would be closed, but I'd like to report that gtk-recordmydesktop is then recording improper ogg's. Is there some ogg validation tool? So I can add information to the bug report.
Pitivi is crashing when opening an mkv, h264. Would this fall under this category? And who's fault would this be?
