Display-switch: Turn a $30 USB switch into a full-featured multi-monitor KVM

I use NDI a lot, but with a phone as webcam, or from obs to obs, scan converter, audio stream between devices like ipad/iphone/Android to desktop... But it is demanding to encode this way. HDMI capture does only use bandwidth over the USB or pcie bus, while ndi uses cpu or gpu.

HDMI capture cards can definitely use CPU, and this is the case for most USB capture cards as USB does not have enough bandwidth to send an entire raw stream in realtime.

Yes, it's MJPEG for the cheap ones.

It's not at all demanding on my RTX2060 but I'm only doing 1080p 60fps - don't know how other cards/resolutions/framerates compare.
