Totem does not play certain videos correctly.

[Haris Ibrahim K. V.]

When trying to play certain mp4 videos downloaded from youtube, certain videos play without any problem. While some others do not play at all and some others play the music but not the video.

The videos are fine as vlc was able to play all of them without any problem.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem.

I'm also having problems with Gnome mplayer, so I was wondering whether the issue was with libav-tools (ffmpeg)?

The same bug seems to affect Minitube when it uses the gstreamer backend.

Been trying to fix this same issue all week (totem opens mp4 files but then just sits there saying 'playing' with a track length 0.00/0.00), have finally installed vlc and that does indeed play them. This is also affecting banshee media player so guess it's gstreamer. have also tried reinstalling totem, totem-plugins-extra, and gstreamer no luck there. noticed that there is no libmp4v2-0 for 12.04 guess it's been replaced? have medibuntu depo and some others - all the codecs I can find and am using gnome panel (2d).

Going to switch the previous bug that was just duped to this the other way around only because I think it's more specific & contains a short sample clip illustrating the issue

Try this:

After executing
mv ~/.gstreamer-0.10/registry*.bin ~/.gstreamer-0.10/registry*.bin.org
the problem was solved

[Jan Kalmar (mr-pytagoras)]

Sorry, the problem isn't solved

I was trying some others videos and some indeed can't be played
