How do I access my webcam in Python?

Question

I would like to access my webcam from Python.

I tried using the VideoCapture extension (tutorial), but that didn\'t work very well for me, I had to work around some

Answer 1

import cv2 as cv

capture = cv.VideoCapture(0)

while True:
    isTrue,frame = capture.read()
    cv.imshow('Video',frame)
    if cv.waitKey(20) & 0xFF==ord('d'):
        break

capture.release()
cv.destroyAllWindows()

0 <-- refers to the camera , replace it with file path to read a video file

cv.waitKey(20) & 0xFF==ord('d') <-- to destroy window when key is pressed
