While youtube is known from violating human rights by censorship and propaganda it's a popular video service. However, some videos are not playing on Fedora 36 and Firefox.
Version-Release number of selected component (if applicable):
It is due GStreamer Multimedia Codecs - H.264 is not installed by default (even if 'enable third party repositories' was selected).
Consider installing above component as well.
Firefox does not use GStreamer but ffmpeg, so you need to install it from rpmfusion, see https://rpmfusion.org/
Thanks. I tried on bare metal and VM and somehow it was enough to install mentioned gstreamer. Apart from this would it be possible to automate the process? I mean new users can be confused and blame Fedora or Firefox for this?
Fedora can't ship ffmpeg from rpmfusion as it contains patented code. That needs to be done by user itself.
I know, but I'm wondering if user can be noticed about this when his video is not playing?
