I have tried with this code. password is mypassword. This is hikvision version DS 2CD1021 I I make this code with opencv 2

import cv2

import numpy as np

capture = cv2.VideoCapture('http://admin:[email protected]:554/videoMain')

size = (int(capture.get(cv2.cv.CV_CAP_PROP_FRAME_WIDTH)),int(capture.get(cv2.cv.CV_CAP_PROP_FRAME_HEIGHT)))

fourcc = cv2.cv.CV_FOURCC('M','J','P','G')

video = cv2.VideoWriter('d',fourcc, 1 ,size)

while (True):

ret, img = capture.read()

video.write(img)

cv2.imshow('forehead', img)

if(cv2.waitKey(27)!=-1):

    break

capture.release()

cv2.destroyAllWindows()

I have error:
