Unfortunately I had a pretty bad experience with jellyfin when trying to switch from plex. Plex works for me in almost all scenarios, mobile, desktop, chromecast, what have you. And I can play multiple feeds simultaneously from my cheap Nuc server. With Jellyfin I had trouble to get video even playing without stuttering/buffering on my phone when on the same network, let alone on mobile internet. I'll probably give it another go in a few months to see how they evolved.

That about lines up with my Jellyfin experience ~18 months ago, although I was coming from (and switched back to) Emby at the time, which Jellyfin was forked from (still evident by all the Emby/MediaBrowser references in folder and file names). Which, IMO, was really interesting, because the codebases were very close to identical for some time yet Emby was orders of magnitude more reliable. I have more and more family accessing my server each month to the point I've almost run out of 'devices' allowed by an Emby 'license,' making Jellyfin a more attractive offering going forward... assuming they've fixed the problems they had at the start.

Hmmm...I might suggest looking into the transcoding settings and changing some things next time you take a look. Because I run Plex alongside Jellyfin (the wife prefers Plex's UI once I tweak it), and it typically runs just as efficiently if not a bit more.

I had some issues with Jellyfin that weren't due to transcoding, still not sure what the cause was.

I had a 2nd gen chromecast that would play half a second and fail, something to do with the data format I think as there was some shenanigans with changing the media container but no real transcoding happening. Solved by getting a newer chromecast which was a nice upgrade anyway.

I also had problems playing on my phone, the integrated player in the app would play video fine while the UI was interacted with, so tapping continuously worked. The picture would freeze up though. Playing through the web UI on the phone worked fine, but I prefer the app. Changing the media player from the integrated to externally through VLC solved that.

So I've found it a bit rough in some cases for me, but there are a ton of Jellyfin apps with nice UI. The core work (transcoding etc) is done by ffmpeg by all the big players (plex, emby, jellyfin) so don't expect much differentiation there.

As other comments suggest, this might be due to transcoding. There is tool Tdarr which transcodes media in advance. h264 could be the safest choice for mobile (hw support) and web.

Sounds like a setup issue, which can be tricky on Jellyfin to get transcoding properly working.

Classic open source alternative feeling. I hope the near future of open source software is more stable and feels identical or better than the closed source options.
