The performance of hardware acceleration in Jellyfin is markedly worse in my experience. My A380 can handle 2-3x more streams in Plex than it can in Jellyfin. My theory is that it’s the jellyfin ffmpeg port slowing things down, but I admittedly don’t have much evidence to back that up beyond the fact that Plex’s transcoder is built on ffmpeg as well.

Plex Relays are a feature, but that’s sort of the point. You get that stability from Plex by default and it works on all clients. There is no realistic way you’re going to get all remote client devices on a VPN for Jellyfin. Maybe one day Jellyfin can offer that as a paid option, a la Nabu Casa for Homeassistant.

Media servers tend to get shared around with friends and family and these edges will start to drive you nuts if you have more than a handful of users. I do not want to try to walk a family member through setting up a VPN on their smart TV.

Yeah, that part about Plex has always bugged me. You can disable logins for your server with allow-listed networks, but most of the non-desktop apps have to log into the Plex platform to run.

This isn’t about want, it’s a reality check. OP said jellyfin is better than Plex now, and by objective measure it is not better for most people yet. False expectations hurt Jellyfin adoption, you need to try it with the expectation of jankiness or you’ll just be annoyed by the edges.

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.
