How to access an IP camera using OpenCV (C++ code) ? is there a way to access with OpenCv+vlc ? (windows 7)

I have tried many ways but some programs give me a gray color empty screen and another just exit the code detecting camera can not be accessed but couldn't find a solution even though program are successfully build in opencv.

I am using Microsoft Visual Studio 2010 with Opencv 2.4.3

These are the specification of my camera.

First you need to discovery the rtsp url of your ONVIF camera. Than you use the code at the @Mayur answered replacing the rtsp url by your rtsp url.

To discovery your rtsp url you can look for on this list: http://www.soleratec.com/support/rtsp/rtsp_listing

Or use some software that find it, I recommend the software onvif-device-tool (link) or the gsoap-onvif (link), both works on Linux, look at your terminal, the rtsp url will be there. After discovery the rtsp url I recommend to test it on vlc player (link), you can test using the menu option "opening network stream" or from command line:

vlc rtsp://your_url

Here's the code which worked for me.

#include <opencv\cv.h>
#include <opencv2\highgui\highgui.hpp>
#include <opencv2\imgproc\imgproc.hpp>
#include <iostream>
#include <stdio.h>

using namespace std;
using namespace cv;

int main()
{
    Mat frame;
    namedWindow("video", 1);
    VideoCapture cap("http://USERID:PASSWORD@IPADDRESS:PORT/video.cgi?resolution=640x360&req_fps=50&.mjpg");
    if(!cap.isOpened())
    {
        cout<<"Camera not found"<<endl;
        getchar();
        return -1;
    }
    while ( cap.isOpened() )
    {
        cap >> frame;
        if(frame.empty()) break;

        imshow("video", frame);
        if(waitKey(30) >= 0) break;
    }   
    return 0;
}
