The problem is that now with Firefox 28, we could not see H264 in Ubuntu 14.04, but we could do it in 12.04
If you want to test: http://www.quirksmode.org/html5/tests/video.html
I try use Aurora (Firefox 30 alpha) on Ubuntu 14.04, no H264 video. I check about:config and media.gstreamer.enabled is true
The same video on Ubuntu 12.04 work fine with Aurora
As i understand, when Firefox have <video> with H264, it use gstreamer who use gstreamer*-ffmpeg who use gstreamer-plugins-bad and gstreamer-plugins-ugly to read H264.
But with LibAv, how does it's work ?? I forget a plugin ?? Firefox use gtsreamer who use gst-libav1.0 and after i don't know.
I find one bug with LibAV in Firefox bugzilla, it's very short: https://bugzilla.mozilla.org/show_bug.cgi?id=801521
@ j^ (j) : In 2011, there a fork in FFmpeg, some developper go away and create Libav.
Ubuntu/Debian maintener choose LibAv: http:// forums. debian. net/viewtopic. php?f=6& t=73558 /launchpad. net/libav/ +packages /launchpad. net/libav

and there are an error message when you launch ffmpeg in terminal:
" *** THIS PROGRAM IS DEPRECATED ***
This program is only provided for compatibility and will be removed in a future release. Please use avconv instead. "
Gstreamer could use the both now: http:// gstreamer. freedesktop. org/releases/ gst-libav/ 0.11.90. html 10-ffmpeg: /launchpad. net/ubuntu/ trusty/ i386/gstreamer0 .10-ffmpeg /launchpad. net/ubuntu/ +source/ gst-libav1. 0
In 14.04 gstreamer1.0-libav make the job of gstreamer0.
