After installing Fedora 31 I had some issues playing movies from Plex with the following error message:
plex error s4032 (manifest)
I solved the issue buy activating the RPM Fusion repositories:
sudo dnf install https://download1.rpmfusion.org/{free/fedora/rpmfusion-free,nonfree/fedora/rpmfusion-nonfree}-release-$(rpm -E %fedora).noarch.rpm
and installing ffmpeg compat libs:
sudo dnf install compat-ffmpeg28 ffmpeg-libs
I am a really lazy person
I got this working on Fedora 37 by running: sudo dnf install *ffmpeg*
