Live stream from /dev/video0

I’m trying to create a Plex channel that live streams my Linux computer’s “/dev/video0” stream. This is a video capture device stream. In my case, this is an HD PVR, but it could also be a webcam, or any video stream in Linux.

I’m guessing that I need to create a supported localhost URL with something life ffmpeg?

Your guess is correct. The channel framework does not support streaming from the filesystem, only network streams.
