So I realized, those files were in a “Concerts” type of library. I copied the files into my “Movies” type library, and alas there they are.
Not sure why though, I can work with that, but I’d prefer they would be in their own library.
Is there anything special with that kind of library I should know about? Or is this a bug?
Lol ok your comment just made me realize my mistake, and I’d probably never see it and just go back to Plex instead.
So what happened is that when I imported my Plex library to Jellyfin I created a library named “Concerts” and content type I probably intended to click “Shows” but clicked “Music” instead which I’m guessing at this point expects only audio files, thus, never listing my concerts files on Jellyfin :)
That said, I think “Shows” is probably also not the correct content type here, I think they meant more like TV shows, like The Office or Friends etc. Probably the right content type is either Music Videos or just Movies.
Anyway thanks for the help, I wouldn’t have noticed my mistake if it weren’t for your comment.
