I just installed jellyfin this weekend and I'm trying it.

IDK why there aren't more open source tools for this, IIRC Emby and Plex are not open source, and using a close source software for watching content from.. the high seas... is a bit risky IMHO.

I recently switched from Plex to Jellyfin due to the former's requirement that users must buy a PlexPass to download media you've shared with them. Relying on streaming for movie nights was a nightmare.

A community developer also recently launched their Plexamp-inspired iOS/Android music player on the stores.

Jellyfin has some serious performance issues. I tried using it on a small 12TB zfs dataset of Linux ISOs and it only indexed ~20% after letting it run for a month. For comparison, my ffprobe scripts only take a day to collect media info about every file and figure out what needs to be transcoded.

The web UI is also a buggy js SPA that doesn't use meaningful URLs with "#". So when it breaks, you can't reload the page and get back to page you were on. It's incredibly frustrating.

Unfortunately, Jellyfin is the only open source video server I could find that kinda sorta works. So this is as good as it gets unless you wanna get your hands dirty and rewrite large parts of it.

nb. I did not try out the online metadata fetching because I didn't want to give it internet access. I assume that enabling online metadata will make the server even slower

Wowie! I just installed this and this friggin rules! All of the features I care about from Plex, plus the ability to enable/disable transcoding on a per-user basis? Yes!
