For some reason the best clients are on Apple devices only, that Infuse and Swiftfin. mpv shim is ok too. That’s my only gripe since I barely touch the actual Jellyfin server interface, it just works. If I had Plex I would also use Infuse too so there’s really no difference except that one is open source, doesn’t phone home, and doesn’t require a monthly subscription.
+1 for the Apple TV mention. I gave up and ordered one to use Infuse, might try out Swiftfin first though, for my Jellyfin setup. It’s always trade offs with the official Jellyfin clients, can’t get everything working 100% of the time with the same setup. I have an Android TV and keep having to switch between LibVLC and ExoPlayer depending on what I’m watching, not to mention the numerous bugs and clunkiness. Like for some reason I can’t wrap my head around, ExoPlayer Jellyfin can’t play ASS and has to transcode the whole file while ExoPlayer Plex can. When you seek before waiting for a previous seek to finish and start playing you end up with a broken stream where the local progress bar and time doesn’t correspond to what’s actually shown on screen. After trying Infuse on my phone, it seems exactly the kind of “just works” I’m looking for.
