This statement is used for Video capture:

cap = cv2.VideoCapture(0)

The problem you are having is that no image is being is read. So please confirm whether you have a webcam or not. Also, try and replace the 0 with any pre-recorded video you might have.

cap = cv2.VideoCapture("video.mp4")

Make sure the path to video is correct or place it in your working directory.
