GNU IceCat will not play videos

I use GNU IceCat. The browser doesn’t play videos.
Does anyone know if there is way to fix this?

Do you use add-ons which are turned-on by default with IceCat? The one for LibreJS and other libre focused stuff? If yes, try to disable all of them first and re-test the video playing.

I have disabled all default GNU IceCat Add-ons except HTTPS Everywhere. I installed uBlock Origin. I only have two Add-ons enabled.

Do you have these packages installed?

Also, are you using RPM Fusion repos for multimedia stuff? There is “Multimedia post-install” available here:

For me it works without any issues with same setup.

What’s the point of using GNU IceCat (free as in GNU) and then install a bunch of non-free codecs and packages?

All the packages from my post are from RPM Fusion free repos - “free for Open Source Software (as defined by the Fedora Licensing Guidelines) which the Fedora project cannot ship due to other reasons”.

Thanks for your reply and help. I have the two packages installed which you mentioned. I used dnf info >package name< on the terminal to query.

I went to the website and installed:

  1. RPM Fusion free for Fedora 33
  2. RPM Fusion non free for Fedora 33
    Then restarted but I get the same message in the screenshot and a message about codec.

It is good to have choices. There are very few open source and privacy browsers. I use Firefox as well. GNU IceCat is more privacy and open source even with the non free codecs and packages installed. In my opinion.

you need ffmpeg-libs package:

sudo dnf install ffmpeg-libs

Sounds like you just installed the repositories, but not yet the codecs mentioned above. Or did you?

Thanks @ersen. I didn’t install codecs. Videos now playing :smiley:
Also thanks to @cltnt for your advice to install RPM Fusion repositories.
