Raring debdiff ** Patch added: "raring.debdiff" https://bugs.launchpad.net/ubuntu/+source/gst-plugins-bad0.10/+bug/973014/+attachment/3434302/+files/raring.debdiff
** Description changed: + Sponsors: Please start by uploading raring.debdiff + SRU Justification (for both Quantal and Precise): [Impact] Several H264 video files are playing back without video output in 12.04 and 12.10. Applications such as totem, totem-mozilla, banshee, minitube, gnome-sushi and transmageddon are affected. [Testcase] Download novideo2.mp4 and open it in totem. The bug shows it self as black screen video output. If it has correct video, the bug is fixed. [Regression Potential] The patch size is quite big. Recommend testing of several types for h264 files to make sure there are no regressions. However; the patch originates from upstream, and a lot of people are already using it without regressions (according to comment #73). Given the number of users affected and duplicates of this bug, I would consider it worth the risk. Please consider this for SRU. ======= Current workaround: The fix has been packaged in this PPA: - https://launchpad.net/~diwic/+archive/gstreamer-h264-testing + https://launchpad.net/~diwic/+archive/gstreamer-h264-testing sudo add-apt-repository ppa:diwic/gstreamer-h264-testing sudo apt-get update sudo apt-get dist-upgrade Restart the affected application(s) and retry. ====== *Adjusted description so as not to show as email to non logged in people Most affected files are Baseline@L2.1, Baseline@L1.1 * Those would be the most likely to fail to be decoded but certainly not limited to kust them. These files are commonly found online though many users will have locally. Also affected other than totem, totem youtube plugin, & banshee would be the mozilla-plugin & minitube. Typically the audio will play with no video though sometimes neither *Moving libgstvideoparsersbad.so to a .bak allows decoding to take place on the previously affected files, but *is not the recommended fix* Upstream has provided a commit to fix in both gstreamer 1.0 & .10 (gst-plugins-bad0.10.23 Attached below is a patch taken from the 0.10.23 commit to be applied to 0.10.22 that's currently used in 12.04 Also attached is a cut small sample file, noting the file plays fine in all non gstreamer players & in all gstreamer players in 11.10 & earlier The file should be playable in totem, banshee & firefox with totem-mozilla plugin installed but only audio is decoded ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: libgstreamer0.10-0 0.10.36-1 ProcVersionSignature: Ubuntu 3.2.0-21.34-generic-pae 3.2.13 Uname: Linux 3.2.0-21-generic-pae i686 NonfreeKernelModules: nvidia ApportVersion: 2.0-0ubuntu3 Architecture: i386 Date: Tue Apr 3 21:33:08 2012 InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Beta i386 (20120301) ProcEnviron: TERM=xterm PATH=(custom, user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: gstreamer0.10 UpgradeStatus: No upgrade log present (probably fresh install) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/973014 Title: gstreamer0.10-plugins-bad, (libgstvideoparsersbad.so), causes a failure to decode many common video files encoded as AVC 1 Baseline - L2.1, Baseline - L1.1 & others To manage notifications about this bug go to: https://bugs.launchpad.net/gstreamer/+bug/973014/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
