Selfhosted

There's a really strong bias on Lemmy for OSS projects. I'm glad they get so much love here, but everything people say here about Jellyfin has to be taken with a huge grain of salt. It works and you can use it. Depending on your needs, it may even work perfectly for you. There are tons of rough edges though.

Here's a few:

• A bunch of basic functionality most people are used to is missing by default. You can get things like intro detection and subtitle downloading to work with plugins, but you have to work at it.
• Hardware acceleration still kind of sucks. You can get it to work, but the Jellyfin port of ffmpeg doesn't work anywhere near as well as Plex's.
• The variety in app experience is bewildering sometimes. Apps look and feel very different between platforms.
• Android TV app support sucks. The app is difficult to navigate and has a bunch of weird edges, like subtitle defaults not working. I have no idea what OP is talking about here, it sounds like they're only judging the app on its animation speed.
• Public network support is finicky. This is hard to quantify, but I've been on several remote networks where my Jellyfin connection dropped in and out and Plex did not. I suspect this is due to the Plex Relay service making up for bad routes between my house and the network.

Jellyfin is improving all the time, and I hope the recent EFCore update improves performance and development velocity. I'm also holding out hope it will eventually lead to externally hosted databases and active-active servers.

Disclaimer: I run Plex and Jellyfin and regularly check in on the state of things in Jellyfin. I donate to Jellyfin. I want Jellyfin to be better than Plex. I don't think any objective measure bears this out yet.
