You rock! The Jellyfin Android TV app on a LineageOS-Pi4 is my current preferred way of bringing Jellyfin to my TV. I tried messing around with Kodi-based solutions for a while but if you don’t like the default behaviors there then it’s an absolute nightmare timesink to reconfigure. AndroidTV Jellyfin client - install, open, everything is in its place already.

I personally nerver really understood the whole semantics debate that always unfolds in situations like this. What does it matter if a piece of software is truly libre or how it is licensed as long as the source code is available? Respecting a license is a choice. If you have the code you can fork it. Whether it’s libre or not only influences your ability to put your real name under the fork, doesn’t it?
