Thank you. The two things I don't like having in Jellyfin are music and youtube videos (the latter are a real PITA if what you've ripped doesn't have a TVDB entry, which, fortunately, some Youtube series do—yeah, there's a 3rd party plugin to help out, but it's so unhelpful I stopped using it completely, broke other stuff, very fiddly, not worth it)
This gives me what looks to be a much-better solution for at least one of those. Looks like I'll be adding another docker container to my server this evening.
