Hi, I want to close the video frame with any key from the keyboard. I have tried with waitKey(0), but it just displays an image. I want to stream the video from webcam and want to close the streaming when I press any key. Is there any better way than passing all the keys at ord()?
# Press 'q' to quit
key = cv2.waitKey(1) & 0xFF
# if the `q` key was pressed, break from the loop
if key == ord('q'):
break
I tested @sturkmen . But doesn't solved problem. I solved problem to fix. You can used both click or press any key to stop.

import cv2
clicked = False
def onMouse(event, x, y, flags, param):
global clicked
if event == cv2.EVENT_LBUTTONUP:
clicked = True
cameraCapture = cv2.VideoCapture(0)
cv2.namedWindow('MyWindow')
cv2.setMouseCallback('MyWindow', onMouse)
print('Showing camera feed. Click window or press any key to stop.')
success, frame = cameraCapture.read()
while cv2.waitKey(1) is -1 and not clicked:
if frame is not None:
cv2.imshow('MyWindow', frame)
success, frame = cameraCapture.read()
cv2.destroyWindow('MyWindow')
