openCV connect and process an ip camera stream (rtsp protocol)

edit

i am trying to connect and process a video stream from my ip camera i am using 360Eye(s) camera.

this is my code trying to connect:

import cv2
cap = cv2.VideoCapture('rtsp://admin:[email protected]')
while True:
    ret, img = cap.read()
    if ret == True:
        cv2.imshow('video output', img)
        k = cv2.waitKey(10)& 0xff
        if k == 27:
            break
cap.release()
cv2.destroyAllWindows()

and i never get inside the if statment
