* MV-MIPI-IMX178M
*method 1，use selection
<code>v4l2-ctl --set-selection=target=crop,top=0,left=0,width=$WIDTH,height=$HEIGHT</code>
The maximum frame rate will be adjusted automatically after setting ROI.
* MV-MIPI-SC130M
*method 2，use user definedroi_x，roi_y and <code>--set-fmt-video</code>
<code>v4l2-ctl --set-selection=target=crop,top=32,left=64,width=640,height=640</code>
<code>v4l2-ctl --set-ctrl roi_x=0</code>
<code>v4l2-ctl --set-ctrl roi_y=0</code>
<code>v4l2-ctl --set-fmt-video=width=$WIDTH,height=$HEIGHT</code>
