It seems like it should be, you just may want to test various encoding settings for your media - for example i have all my stuff in m4v containers with h264 and h265 encoding bc i know for certain that directly plays on my apple tv without needing to transcode.
I’m sure that will be fine, but just watch out for any media incompatibilities that may require transcoding (unless your server can handle it just fine)
Soon™ it’ll be on the store. Having to build and push to tizen is the absolute worst part of jellyfin (if you have to) otherwise there’s clients for every platform - even LG’s webOS.
There’s also finamp for music specific playback, so jellyfin can pretty much do everything
