I'm really not sure how much work this would be (it may be prohibitively difficult), but it would be amazing to have a plugin for Plex that would allow one to filter the movie files one streams on one's Plex server.
Actually imperceptor doesn't look really full fledged yet...dang it, wish I had time to address more of these issues :|
I haven't worked on "raw files" for quite awhile. I did see this recently maybe it does plex? https://imperceptor.com/
