does 9152x6944 [2.70 fps - (0, 0)/9248x6944 crop] mean that when i use this mode i get a cropped area from sensor where the area starts from x=0, y=0 to x=9152, y=6944? if yes then why isnt the area centered on the x axis, like there should be 36 pixels from sensor area both left and right of the cropped area for it to be centered on the sensor. so the area would be x=36, y=0 to x=9188, y=6944
