Hi!
I feel like this has been answered somewhere but could not find any information. Could you point me to some resources or help me out with the following:
I have two cams attached to an USB Oak board FFC3. However, the lighting for the two cameras is different. I want both of them to have auto-exposure, but independently from another. In my current implementation, I believe that one cam controls the auto-exposure for both. How would I change that?
