Enabling Html5 Videos in Fedora Firefox

How do i enable Videos playing in Fedora ? YouTube works fine. But other Websites like Facebook do not play videos and some other sites say Html5: Video not properly encoded.

In Firefox ESR in Debian everything works fine.


Hello Alex,

I was able to have HTML5 video by installing ffmpeg package that is available in the rpmfusion repo.

You can find how to install software in your template VM here: Installing and updating software in domUs | Qubes OS

When the repo is enable, you just have to do:
sudo dnf ffmpeg

Shutdown your template, start your App VM and test!

Good luck!
