Open CV frame opens and closes immediately-CodePudding

here is a code snippet im running in VS 'cap = cv2.VideoCapture(0) while cap.isOpened():

ret, frame = cap.read()
cv2.imshow('OpenCV feed', frame)

#breaks for a while
if cv2.waitKey(10) & 0xFF == ord('e'):

    break
cap.release()
cv2.destroyAllWindows()`

but it closes immediately it runs, what did i do wrong??

CodePudding user response：

Because break cannot be used to break out of an if - it can only break out of loops.

Perhaps you should use sys.exit() or return instead?

CodePudding user response：

Try this:

if cv2.waitKey(10) & 0xFF == ord('e'):
    cv2.destroyAllWindows()
    break
