利用OpenCV读取大华网络摄像头

项目需要将网络摄像头接入到服务器上，用c++或者python处理每帧的图像。查了很多资料总算解决了，回过头发现是很小的问题，但是大华官网的SDK真的很难看懂。OpenCV2.4。
直接上代码吧。

#include "cv.h"#include "highgui.h"#include <stdio.h>using namespace std;using namespace cv;int main(int, char**) {    VideoCapture vcap;    Mat image;    const string videoStreamAddress = "rtsp://admin:dahua@192.168.1.108/cam/realmonitor?channel=1&subtype=0";    /* it may be an address of an mjpeg stream,    e.g. "http://user:pass@cam_address:8081/cgi/mjpg/mjpg.cgi?.mjpg" */    //open the video stream and make sure it's opened    if(!vcap.open(videoStreamAddress)) {        cout << "Error opening video stream or file" << endl;        return -1;    }else{       cout<<"success"<<endl;    }    //Create output window for displaying frames.    //It's important to create this window outside of the `for` loop    //Otherwise this window will be created automatically each time you call    //`imshow(...)`, which is very inefficient.    namedWindow("Output Window");    for(;;) {        if(!vcap.read(image)) {            cout << "No frame" << endl;            waitKey();        }        imshow("Output Window", image);        if(waitKey(1) >= 0) break;    }}

大华的网络摄像头编号：DH-IPC-HFW1225M-I1-0600B，用的是RTSP协议。
“rtsp://admin:dahua@192.168.1.108/cam/realmonitor?channel=1&subtype=0”;
其中的admin，dahua是登录摄像头的用户名和密码。IP地址是192.168.1.108，可以根据具体情况修改。
