The command is not correct should be like below. “–set-ctrl exposure=xxx” instead of “–set-ctrl=exposure=33333”
v4l2-ctl -d /dev/video0 --set-fmt-video=width=3280,height=2464,pixelformat=RG10 --set-ctrl exposure=33300,gain=110,bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=test_3280x2464.raw
