I tried Kodi with Libelec but it’s still so jank. The Plex app is broken, there is no invidious or YouTube app I found that works. And sometimes it just “thinks” forever and I need to get up and unplug it.
I saw that Plasma Bigscreen was revived and it looks promising, but they don’t have a release yet.
Are there any other options?
Android TV is FOSS, but given Google’s recent announcement I wouldn’t take it’s future openness for granted.
That said, I think it’s the best FOSS OS for TVs.
