Difference in output with waitKey(0) and waitKey(1)

Question

I\'ve just begun using the OpenCV library for Python and came across something I didn\'t understand.

cap = cv2.VideoCapture(0)

while True:
      ret, frame =         


        

Answer 1

cv2.waitkey(1) is being used in while loop.It shows the output for 1msec but because of infinite while loop it is the sequence of images that are perceived by our brain as a single continuos video.

Hope this helped.
