SOLVED: Ffmpeg error 254 Fedora

[Raskoll]

Hi first time poster and fedora user, I did a clean install of fedora 42 with COSMIC DE, installed ffmpeg through the rpm on the website and that went well. Set up a library no problems, in pop os I previously had to mess with permissions. Playback failed tho due to a HLS issue, that changed after a restart to a generic fatal playback error. I uninstalled ffmpeg (which uninstalled jellyfin lol) so reinstalled jellyfin. I then downloaded the custom binary and replace /usr/bin/ffmpeg with it, no luck.
Logs are here. Idk if these are the right logs I just copied the std out. https://privatebin.net/?d5e6c9da9a0da6ce#8DhxjyZAS8hvJU8bwXxWCbnCobYBsWBQjzZVUjMkbtuS

This might help too:

I'm on an intel nuc btw, i5-6260U 8GB ram and an iGPU. Linux 6.14.0-63.fc42.x86_64

Fixed it.
Problem: Incompetence
Solution: Mount the hard drive the library's on.

It's a fresh install so I forgot to set the auto mounting rules lol.
