@ 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 https://launchpad.net/libav/+packages https://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 In 14.04 gstreamer1.0-libav make the job of gstreamer0.10-ffmpeg: https://launchpad.net/ubuntu/trusty/i386/gstreamer0.10-ffmpeg https://launchpad.net/ubuntu/+source/gst-libav1.0 FFmpeg could come back to Debian: http://www.phoronix.com/scan.php?page=news_item&px=MTYxNjA 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 ** Bug watch added: Mozilla Bugzilla #801521 https://bugzilla.mozilla.org/show_bug.cgi?id=801521 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1051559 Title: Build Firefox with GStreamer 1.0 support Status in The Mozilla Firefox Browser: Fix Released Status in “firefox” package in Ubuntu: Triaged Status in “iceweasel” package in Debian: Fix Released Status in “firefox” package in Fedora: Unknown Bug description: Building Firefox with GStreamer support would provide support for a lot of websites that use h264.
