I have gone through the docs support.plex.tv/hc/en-us/articles/205568377-Adding-Local-Artist-and-Music-Videos
My music track is
Album Name - track# - track name.mp3
and the video track is:
Album Name - track# - track name-video.mp4
So what’s supposed to happen now? I have rescanned the library, but I don’t see the videos in the track list.
