Ubuntu – How to get HTML5 h.264 Video working on Firefox


According the the release notes for Firefox 26, h.264 video should now be working in Linux. It does also say the appropriate gstreamer plug-ins need to be installed. Does anyone know what these are?

I used this test site and the YouTube HTML5 page to verify that h.264 support works in Google Chrome on my Ubuntu 12.04 64-bit, but does not work on Firefox 26.

Best Answer

For 12.04 / 14.04 / 18.10

Just visited the HTML5 Youtube test and I have H.264 checked; you probably will need to install Ubuntu restricted extras to get the gstreamer codecs.

sudo apt-get install ubuntu-restricted-extras

You may need to restart.
