Just upgraded to trusty. there is no package "gstreamer0.10-ffmpeg": # apt-get install gstreamer0.10-ffmpeg Package gstreamer0.10-ffmpeg is not available, but is referred to by another package.
It is rumoured that one has to use libav nowadays. It would have been nice if the upgrade process had taken care of that. # apt-get install gstreamer1.0-libav But that doesnt help. The previous comment suggest that firefox-30 might be needed. # apt-get remove firefox Removing firefox (29.0+build1-0ubuntu0.12.10.3) ... # apt-get install firefox Setting up firefox (32.0+build1-0ubuntu0.14.04.1) ... Maybe the version is 32 now. But no mp4 videos are played. Maybe someone can publish a sequence of steps to follow in order to get a trusty with firefox that plays mp4? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1280905 Title: firefox on ubuntu 14.04 does not play mp4 files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1280905/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
