UDP Pi Mapping
1/29/26
I can send a video signal to an infinite number of analog televisions, regardless of their input type. That can be done live, looped, or event comepletely wireless on a VHF band. What can take this art form to the next level is mapping a wall of various CRTs to act as one display. I am currently working on a udp method - not NDI. This is limiting, as a computer has to stream each video tile to an RPI individually, but it's a stepping stone to learn more about video mapping. Signal flow goes like this:
Resolume
Resolume is communicating to OBS through syphoning. An entire video can be divided up into slices in Resolume and then syphoned to OBS individually. Think of a slice as a video panel. I can customize the orientation and size depending on the CRT I wish to send a slice to. OBS inputs a slice, and then I can stream it to a Pi’s IP address for video playback. This method is limiting. If I wanted to build a wall out of thirty CRTs, one laptop would not be able to sustain thirty streams. But on a smaller scale, it does work. It’s one more step in the correct direction.
