Populate a "Now Playing" Marquee from Plex

I’d like to make an automated marquee for my home theater. Specifically, I’d like to find a way for a single-board computer (Raspberry PI or something) to receive notifications of what a specific player is playing, and have it display that title (and maybe poster?!) in a marquee format.

Is there some sort of API that would serve this need? Or is there a known approach to getting this information from the Plex Server? Would be VERY happy with an “RTFM” answer . . . as long as it includes where to find the FM :wink:

no idea if it’s still alive: https://forums.plex.tv/discussion/226628/rel-plex-movie-poster-display/p1#top

If you can code yourself, you could also write your own ‘webhooks’ processor, which ingests the webhook your Plex server is sending. This was not available back when the above solution was created.
