pixelformat : 0x31384142 [BA81]so it's using bayer. But in dmesg I get yuv420 which changes to raw when I start mplayer (I don't know if this is of any use) [68140.921791] sn9c20x: Webcam device 0C45:6270 is now controlling video device /dev/video0 [68140.934259] sn9c20x: Using yuv420 output format starting mplayer [68162.705023] sn9c20x: Using raw output format I have attached the output of v2l-info. Is there any cure for our problem, and why brightness control works for Boris on older version? Boris - can you tell me from when dates your driver to test it on my hardware?
