We are using a OAK-D-FFC board to stream depth and multiple 1080p H264 videos using the USB 3.1 port to our main computer.
We have other constraints what could be solved by using an OAK-D-CM4 like design. In that case, we would use the RPI ethernet port for connexion to stream video flux from the camera to the main computer.
However I'm a bit concerned by the potential additionnal delay it can bring.
Solution 1: camera ==FFC=> Oak-D ==USB 3.1==> main compter
Solution 2: camera ==FFC-like==> Oak-D ==???==> RPI ==Ethernet==> main computer
As we are doing mobile robotics, delay is very critical and we have to keep as small as possible. I guess the solution 2 is worst but I don't know if that's a significant difference (i.e adding >1ms delay).
Do you have information or at least a gut feeling to share about that ?
