The equivalent GStreamer 1.0 package to gstreamer0.10-ffmpeg is gst- libav1.0, which does have an enabled H.264 decoder. Ubuntu 13.10 "Saucy Salamander" has gst-libav1.0 1.0.10-1ubuntu1 and Ubuntu 14.04 "Trusty Tahr" has gst-libav1.0 1.2.3-1.
GStreamer 0.10 H.264 support was first enabled by default on Linux in Firefox 26. On earlier Firefox versions you will need to go to about:config and toggle the media.gstreamer.enabled preference. However upstream Firefox has only just updated this support to GStreamer 1.0 and it wont be released until Firefox 30.0 (approx June 6th) - see https://bugzilla.mozilla.org/show_bug.cgi?id=806917 ** Bug watch added: Mozilla Bugzilla #806917 https://bugzilla.mozilla.org/show_bug.cgi?id=806917 -- 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
