this picture generate by script:

gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM),width=1920, height=1080, framerate=30/1' ! nvjpegenc  ! filesink location=test.jpg

And in my opencv application, our script is:

nvarguscamerasrc ! video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, framerate=(fraction)30/1 ! nvvidconv flip-method=0 ! video/x-raw, width=(int)1920, height=(int)1080, format=(string)BGRx ! videoconvert ! video/x-raw, format=(string)BGR ! appsink

it’s a 12-bit Bayer RGRG/GBGB input CSI camera, but with multi debugging, image also looks like closer to green, such as x-bayer, format=nv12 or format=grrb also not useful. what’s the right way to do?

after camera manufacturer give me the isp define file，this problem has been resovled, thanks all
