I’ve feel like I’ve used Plex forever. I also feel like every couple years I try Jellyfin to see how it’s going. Recently I tried it again because of Plex restriction on more than one user.
Well, I just tried it again and it’s substantially improved! This time it actually properly detected most of my library!
Also the Android TV app is AWESOME! No more glitches, lagging, and freezing trying to play my stuff like Plex did. It is butter smooth.
Wow! I’m impressed and I just deleted Plex. Good riddance.
If you enable the “remote access” in Plex you are essentially port forwarding you server to the internet using UPnP (by default. You can also port forward manually if you’d like).
It’s indeed a point to point connection but a point to point connection the same way your connection to normal websites are point to point.
If you knew the public IP of anyone that’s using Plex you can likely go to [IP]:[Random PORT] and access their server. You still need to login though.
