As much as I hate what Plex has been doing in the last period, here Jellyfin is not as good as Plex. Plex tablet and TV UX feels simpler and easier than OOTB Jellyfin, unless you tinker with it or use alternative clients. My parents far prefer Plex's UX.
Also, what grinds my gears the most is that most movies and shows I download, Jellyfin can't detect what content it is, and instead just lists them as raw video files in a folder since it expects a strict naming convention which most torrents don't follow. Plex seems to have a much better content detection engine, probably based on fingerprinting, since it rarely misses, regardless of how fucked the naming convention is.
Also 2, I noticed transcoding on Plex is somehow more power efficient than Jellyfin. When I monitor intel_gpu_top on my 12th gen NUC, Plex hammers the iGPU with far less interrupts than Jellyfin, resulting in noticeably lower power consumption.
No, mostly US/Western productions. Clarkson's Farm, Stargate SG-1 for example.
My only annoyance with the Android TV client is that preferences for audio/subs don't stick within a TV series. If I set audio to JP and subs to EN on episode 1, I expect that the preference would carry over next episode, but it doesn't always.
That's a really minor thing, though. Non techie relative doesn't have a problem with playback.
If anyone is interested I may do a post about this app, but I figure in the AI age you'd probably rather I keep it to myself!
I'm not up to speed on transcoding, but I do notice my web users always have to transcode, assuming due to their native browser playback support for codecs. Local installs of the Jellyfin player seem to avoid this on most systems.
Send them a hostname, username and password. Jellystat is a nice companion app if you like seeing metrics.
every time i've checked in with Jellyfin, the ecosystem has been way too fragmented to consider migrating.
