Problems you were having?
Now I am trying to control the camera’s exposure using OpenCV, but setting properties does not work. For example, even you set CAP_PROP_EXPOSURE to -7.0 that does not stick and it is still the default value, 0. Below is my code.
cap = cv2.VideoCapture(0)
print(cap.get(cv2.CAP_PROP_AUTO_EXPOSURE)) #This returns 0
print(cap.get(cv2.CAP_PROP_EXPOSURE)) #This returns 0
Am I doing something wrong?
