Error line 33 - initializing camera

[ooftv]

I had to change line 33 from:
self.capture = cv2.VideoCapture(cv2.CAP_DSHOW)
to
self.capture = cv2.VideoCapture(0)
in order to work with the built-in webcam on a macbook pro running Mojave.

It's an issue with cv2.Videocapture(), on different systems it requires different arguments passed for it to work. I'll add it to the readme and also will try to find a work around way so it uses (0) when needed and (CAP_DSHOW) when needed. Thank you.
