Due to illness I was unable to continue the tests with the ov3640 sensor. You said that at first I need to configure the pipeline for the isp.

might have done wrong? And I have one additional question. When I want to change the format through my application. Do I need to change the format on all three pads or would it be enought to call the ioctl just for the video device (video2)? I still hope that I don't annoy you too much.
