Yeah, I am too lazy to set up something like Jellyfin. It only makes sense for me with music, for which I use Navidrome. But again, my setup is mostly directory/filename based, so it’s really being carried with m3u playlists as opposed to proper metadata.

I mean, maybe I’ll use Jellyfin if I’ll do something in a proper way, but currently I don’t see the point of it. And anyway, I can always copy the URLs to VLC, which will even accept DVD ISO files.
e.g.:

vlc --no-dvdnav-menu http/dvdnav://192.168.49.1:8080/media/ISOs/Interstellar.iso

let’s me play entire copy of a DVD, properly with menus and bonus features, just as if I used the DVD directly.

Although I don’t do this anymore because of storage limitations, but I’ll likely return back to it once I’ll have a proper media server and LAN.
