4 years ago Hmm need to google a little bit, seems this is not an issue with my module. Maybe you can find a solution in this blog post?
https://www.pyimagesearch.com/2016/12/26/opencv-resolving-nonetype-errors/
They say one of this is possible? Can you please check this?
- An invalid image path passed to cv2.imread .
- A problem reading a frame from a video stream/video file via cv2.VideoCapture and the associated .read method.

Running into the following error when livestream is starting:

Have tried debugging but without much success unfortunately. Some help would be appreciated!
