Add support Creality K2 Plus 3D printer camera #1600
Description
I'm trying to set up my Creality K2 Plus 3D printer camera in my HomeAssistant.
The camera is available on port 8000 of the printer IP. But of course this is a JavaScript wrapper doing all the WebRTC/stun "magic".
As I'm very new to WebRTC stuff, I'd be more than happy if someone could point me in the right direction on how to configure the stream in go2rtc.
