while cap.isOpened():

    ret, frame = cap.read()

    # Our operations on the frame come here
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
   
    # Display the resulting frame
    cv2.imshow('frame',frame)
    cv2.imshow('gray',gray)
    if cv2.waitKey(20) & 0xFF == ord('q'):
        break

# When everything done, release the capture
cap.release()
