There is a function in CamEx2, setAutoExposureMode, which can be used to disable AutoExposure.
But I don't find it in Camera libray and CameraExClass.
The reason I am using Camera Library instead of Camera2, is that, I want to process yuvData() directly in Camera_Preview Sub.
And I don't know how to do it with Camera2.
So please help me to solve this problem.
Either disabling AutoExposure using Camera Library, or accessing yuvData() in Camera_Preview using Camera2.
