A workaround I just found: go to /usr/share/thumbnailers edit totem-video.thumbnailer instead of using totem-video-thumbnailer use ffmpegthumbnailer -i %u -o %o after having installed it then cancel the folder ~/.thumbnails/ Finally logout and login

Totem does not crash, but displays a black screen. As a result, totem-video-thumbnailer fails to create a proper snapshot to be used as a thumbnail for those videos in Nautilus (it aborts with a "totem-video-thumbnailer couldn't process file: 'video.mp4' Reason: Took too much time to process." error message) This is a regression as everything was fine in 11.10 using the same videos. Moreover, other media players such as VLC or SMPlayer have no trouble playing the video. Steps to reproduce - Download a video from youtube using minitube or the DownloadHelper Firefox plugin - check that Nautilus does not display a snapshot of the video as a thumbnail - check that Totem fails to properly plays the video, although it does not crash - check that it is not the case in 11.10 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: libgstreamer0.10-0 0.10.36-1 ProcVersionSignature: Ubuntu 3.2.0-22.35-generic-pae 3.2.14 Uname: Linux 3.2.0-22-generic-pae i686 ApportVersion: 2.0-0ubuntu4 Architecture: i386 Date: Mon Apr 9 10:11:47 2012 InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release i386 (20110427.1) SourcePackage: gstreamer0.10 UpgradeStatus: Upgraded to precise on 2012-03-29 (10 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gstreamer0.10/+bug/977048/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
