I have gone through https://rpmfusion.org/Configuration#Command\_Line\_Setup\_using\_rpm https://rpmfusion.org/Howto/Multimedia but something appears to be missing, e.g. Dragon Player: Could not locate full support for the H.264 video codec; video playback support may be less reliable than expected.…

Firefox works fine with the default codecs in fedora workstation 40. I need to use SimpleScreenRecorder (SRR), and had installed x264 from rpm-fusion to create mp4 videos there. After that Firefox is playing YouTube videos with stuttering video example These packages aren’t installed ❯ dnf list…

Ok, so… I’ve been trying to get VLC running correctly on my Fedora 43 (KDE Plasma) install for a couple of days now. Yesterday, I had it playing all videos, only with weird audio glitches which I could not figure out. So I restored a snapshot from yesterday before I started messing with all this, a…

I was having issues playing some files in VLC due to missing codecs, so I did an internet search and discovered the whole “RPM Fusion” thing. Installed a bunch of codecs from there, and now I don’t get any more “missing codec” errors, but I do get flaky, weird, jumpy audio from literally everything…

I’m using the Fedora Silverblue 40 beta. In 39 and before, I used to layer the mozilla-openh264 package to add h264 video playback support to Firefox. mozilla-openh264 depends on openh264, but openh264 is explicitly excluded from f40 because of a new noopenh264 package that conflicts with it.

You may encounter that your preinstalled Firefox can’t play videos or certain video thumbnails are missing in your file manager. This is due to missing nonfree codecs, that the Fedora Project would need to pay an enormous amount of money for, thus they can’t possibly preinstall it. There is rpmfus…

This is not really a question, but more a FYI, as it has already been diagnosed on the discussion of Chromium issue 1519639 that its inability to dynamically load openH264 libs on Fedora makes it unable to stream video (camera feed and screen sharing) on MS Teams video and other sites that depend on…
