What I have
I’m running a plex instance in docker off my local NAS with libraries shared to users outside my house. Users have been using it for years without issue.
I’ve recently added a preroll clip to my library- it works great on my end; when I play a movie I can see the preroll just fine. But external users are unable to see it (they have opted into preroll via the player setting Cinema Trailers to Play Before Movies).
My preroll path is something like /extras/preroll.mkv.
What I want
External users should see the preroll clip before their movies on my shared libraries if they have opted in, enabling trailers in their own plex player (be it webOS app or the website).
What I’be tried
I’ve seen a few posts mentioning preroll needed to be in shared libraries to be played by external users and links to it should be used instead of filesystem paths; I tried this without luck, but I don’t know if I did what was ‘correct’ or ‘sufficient’ because I cannot find any guide or information on how to actually do this; the posts comments just mention those bits of information in passing while talking about other problems.
Is it possible that my users also have to be plex pass subscribers? Does it have to be in the same shared library or just a shared library they have access to? Or is anyone able to provide documentation / insight about how to enable this?
