Good day!
I am using Dev-C++ as my IDE and the library OpenCV. I need to fetch the video taken by my IP camera and process it using the OpenCV. Can someone teach me how will I gonna do it. My OS is windows 7 64 bit. Thank you very much..
if it's a recent opencv version, this might work:
Mat frame;
namedWindow("video", 1);
VideoCapture cap("http://150.214.93.55/mjpg/video.mjpg");
while ( cap.isOpened() )
{
cap >> frame;
if(frame.empty()) break;
imshow("video", frame);
if(waitKey(30) >= 0) break;
}
one way or the other, opencv seems to insist, that the url must end with ".mjpg" (dot mjpg), so if it doesn't, add a dummy param to it, like : my/fancy/url?type=.mjpg
