Hello everyone.

I'm working with a USB camera that sometimes fails with the infamous select timeout issue. I'm working on fixing that but for now I just want to manually shutdown and restart the camera port whenever this happens.

So here is my question: how can I catch a select timeout error? I'm thinking something along these lines:

cap = cv2.VideoCapture(0)

while(True):
try:
    success, frame = cap.read()
except SelectTimeoutException:
    restart_port()
    ...

The problem is that either OpenCV is not actually raising a Python error but rather printing directly or there is already a Try/Except block somewhere in the cv2 source catching the exception.

I'd appreciate any help.
