OpenCV and WIFI IP Camera Issue

[Sam Berry]

Hey,

Iv installed OpenCV on my windows machine. I can successfully view the camera stream from my laptop so the installation was successful. However when i edited the code adding in the address of my IP camera like so....

import cv2

cv2.namedWindow("preview")
vc = cv2.VideoCapture('http://192.168.1.72:1025/videostream.cgiUSERNAMEANDPASSWORD')

if vc.isOpened(): # try to get the first frame
rval, frame = vc.read()
else:
rval = False

while rval:
cv2.imshow("preview", frame)
rval, frame = vc.read()
key = cv2.waitKey(20)
if key == 27: # exit on ESC
break

When run, python tries to open the window to display the camera feed then closes before displaying the feed. Anyone have any ideas why? I read somewhere that there is an issue with this been run on windows?

Any insight would be appreciated! Im all googled out.

Thanks, Sam

I wonder whether you should be waiting for the key and _then_ reading
the next frame.
