Please describe your bug

When I have DLNA enabled and access it, Jellyfin shows an empty folder for one of my libraries even though it isn't empty. In particular my movies directory and some of my genre folder. However, my other folders seemingly work correctly. When I copy over the same files to another directory, make a new library, and try to use it. The same problem persists.

Jellyfin Version

10.8.0

I have this problem on ArchLinux using version 10.8.7
I installed it using "Generic Linux" tarball.

@SandyRodgers-2017 Do you have any idea what could cause this problem?

Nope. Not even a little bit. It is why I made the issue thread. My issues were fixed by 10.8.1. It seems that every few updates DLNA breaks. I would suggest downgrading if you can to a release that worked previously for you, if it isn't too old of course. Right now I am on 10.8.3 and it works well enough.

Wait... What is this log error doing here? Is the DLNA plugin re-scanning media for itself rather than using the metadata already in the Jellyfin database?
