i want to build a video switch basically it would have two analog video/audio input (i'm thinking of the typical yellow/white/red cables) and one video/audio output (same format)
so in = 6 wires out = 3 wires
then from host PC i would need to send requests on the USB wire such as * connect video intput 1 to video output * connect audio Left input 1 to audio left output * connect video intput 2 to video output etc.
(and get command result back)
i don't need the arduino to do anything on the video/audio stream as an option it would be nice to know if i have anything at all on a given input cable (maybe detect voltage, i don't know)
i'm terrible when it comes to hardware (software is ok) sorry if this sounds obvious, but is this even doable with an arduino ?
