      opencv代码：

 }

 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");

 while (cvWaitKey(10)!=atoi("q")){
 double t1=(double)cvGetTickCount();
