Hyperion.ng currently has no way to receive a raw UDP stream itself.
For example this can be used to use ColorChord with Hyperion.ng
Just run go build .
Basically it's just ./hyperudp <Hyperion IP>
This, by default, opens a UDP socket on port 1337. Any color data sent there should appear as a video feed in Hyperion and thus on your connected RGB devices
For more advanced settings please see ./hyperudp --help
