camera resolution change as well jit.contact
I am continuously facing issue with webcam and max.
both camera in the picture below are the same cameras (c270)
both get the same format but one seems to display 640x480 and the other 1280x720. Why is that?

adapt 1 means adapt the output dims to the format. so you're setting conflicting information in your box arguments. i would just remove all those args, and it will default to adapt 1. then you use the format attribute (and the getformatlist message) to set the output dimensions based on format.
