I’ve been using fedora on a small intel 6th gen or newer mini pc. I then cook up some custom launch scripts that cause JMP to run at login. I use cockpit and a CMK agent for remote monitoring and management.
I got sick of the lack certificate management on Android TV and how much you need to do to make it reasonably private.
If you are on the latest mesa drivers (hence fedora over a more LTS release), and you install Jellfin Media Player via flatpak, everything should just work with hardware decoding.
