The colorfmt is the sensor output format. You need to know what type of format is out from the tw9992. And your can use the below command to capture the raw image.
v4l2-ctl -d /dev/video0 --set-fmt-video=width=720,height=480,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=ov1080.raw
In the probe function “common_data->colorfmt = camera_common_find_datafmt(V4L2_MBUS_FMT_SRGGB10_1X10)”, is it correct?
