ti ae codec is used to calculate the brightness of image. but i find that if i change the h3a ROI width and height, h3a seems working abnormal. the brightness calculated is over 0xff such like 771. The test is show that h3a cann't support changing the ROI width and height when the h3a is running or settingup. I wonder if the result is true. I hope TI enginneer can give me the answer. If it's supported, how to do it. Thanks a lot.
