Last I checked, they didn't support my webos version without me doing the developer mode trick, but my Nvidia shield/ Jellyfin for Android TV works like a charm
I can't speak for any specific version - but for awhile it was the same for me, but they eventually made a WebOS official release so I no longer have to fuss with developer mode.
Since it can't reach the Internet since that point ( maybe a year ago?) I can't vouch for if any update would have broken that
Oh no I have an old laptop literally strapped to the back on my TV. It's running the Jellyfin server (among many other things) and I installed Kodi on it along with a PC connected remote to control it.
The jellyfin apps have a way better UX than Kodi. Jellyfin gives you only what you need in a clean, familiar design that feels like a real streaming service. Kodi is massively overbloated garbage with a confusing and extremely cluttered UI. Typical programmer-designed interface.
I hate Kodi and avoid it always, which thankfully is very easy thanks to jellyfin
You could have both, I just found Kodi to be a pain to use and set up. But one advantage of Kodi is that I believe it already supports streams like that. With Jellyfin you might have to do some magic. Kodi is more feature rich than jellyfin in general so if you can get it to work well, you could just have Kodi instead of both.
But I'm not sure on this topic. It's probably best to consult the docs for both.
I have Kodi set up, and it seems to work well. There are different ways to do it, I did the database merge option which prevents you having non-jellyfin files in your library but it works nicely.
I also have broadcast TV streams and Disney+ through there too, which gives it a smart-TV feeling which is nice for others using it.
No, the jellyfin app is mainly for using a jellyfin server. And for that purpose, it's really good I think.
It's not like an all purpose media player with tons of add-ons and highly customizable like Kodi is.
I use the Android and Android TV apps. They're fine overall, but have a few usability issues. Main problem is the lack of offline mode. You can download stuff to your device but then have to hunt down the file and manually play it like a caveman.
I use the Android app, and yeah, I wish you could download and play like on commercial streaming apps. It's not just the hunting down of the file, but also the remembering how much of the episode you've watched when part way through, and having Jellyfin know that you've watched the episode so the play next is right.
After making this comment I looked for alternative clients. I came across Findroid, it's a little rough around the edges but the core functionality is here, and downloading/offline mode seem to work fine!
