This is something I first saw at first branch and I have continued monitoring it since. There has been no change.
The problem is that MP4, and AVI videos will not play on Totem. This is probably not a blocker based on the current criteria. I doubt that a bug report is even a proper thing to do. However this seems likely to cause some discontent and commentary.
My current clean install is from Fedora-WS-Live-37-20221013-n-0. It is fully updated. I have also loaded the Free video codecs from RPMFusion.org. In Software --> Codecs when I try to install the the gstreamer-libav Software says it's not available. So it can't be installed. I've looked for it on RPMFusion.org with no luck. I found gstreamer1-plugin-libav in the fedora repo then installed in and did a reboot. This solved the problem. MP4, and AVI videos now play in totem. Software --> Codecs still says that gstreamer-libav is not available.
I think this either needs to be installed by default and remove it from Software --> Codecs or put it back in RPMFusion.org where it can be installed the way users are used to. For now I'll just add it to my install script.
Have a Great Day!
