opencv读取手机摄像头

测试：

浏览器可以直接输入网址，弹出框输入用户名密码进行读取。

      opencv代码：
      #include <stdio.h>
      #include <opencv2/opencv.hpp>
      #include <iostream>
      int main(int, char**) {
       cv::VideoCapture vcap;
       cv::Mat image;
      // This works on a D-Link CDS-932L
      const std::string videoStreamAddress = "http://<username:password>@<ip_address>/video.cgi?.mjpg";
      //open the video stream and make sure it's opened
      if(!vcap.open(videoStreamAddress)) {
      std::cout << "Error opening video stream or file" << std::endl;
      return -1;
      }
      for(;;) {
      if(!vcap.read(image)) {
      std::cout << "No frame" << std::endl;
       cv::waitKey();
      }
       cv::imshow("Output Window", image);
      if(cv::waitKey(1) >= 0) break;
      }
      }
        这个图是白色的：
  
   CvCapture *camera=cvCaptureFromFile("http://admin:admin@192.168.1.2:8081/axis-cgi/mjpg/video.cgi?resolution=640x480&req_fps=30&.mjpg");
 if (camera==NULL){
 printf("camera is null\n");
 return -1;
 }
 else printf("camera is not null");
 cvNamedWindow("img");
 while (cvWaitKey(10)!=atoi("q")){
 double t1=(double)cvGetTickCount();
 IplImage *img=cvQueryFrame(camera);
 if(!img)break;
cvShowImage("img1",img);
 double t2=(double)cvGetTickCount(); printf("time: %gms  fps: %.2g\n",(t2-t1)/(cvGetTickFrequency()*1000.), 1000./((t2-t1)/(cvGetTickFrequency()*1000.)));
 } cvReleaseCapture(&camera);
