From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I somehow keep running across videos that won't load in Clapper, Showtime, mpv, VLC, or Handbrake, and Nautilus won't show thumbnails for them. It's very frustrating. Supposedly I've already installed all the available codecs from RPMFusion, but still get the "codec missing" error on a bunch of videos.
Jellyfin on the other hand, it plays everything I've ever thrown at it. I don't know what the hell it's doing differently from the other video players on my system, but it works great.
Thanks, yeah I think so. At least, I've followed all the steps outlined here https://rpmfusion.org/Howto/Multimedia but VLC and gstreamer apps continue to tell me that I'm missing codecs. I am stumped, but happy that at least Jellyfin plays everything.
I think it actually uses GStreamer as a backend which is a bit unfortunate because HDR support is either nonexistent or hit or miss with GStreamer at the moment. I’ve also had worse performance with GST over MPV, but most videos and codecs are fine. It certainly integrates better with the GNOME environment which may have been a driving factor in the decision to use it over MPV.
