QT 4.7.6 驱动 罗技C720摄像头

编译器： mingw32 gcc 4.8.1 

            mingw32 g++ 4.8.1 

QT 版本： 4.8.6 

OpenCV版本： 3.0.0 

测试平台： win7 x64 

-----------------------

重点： OpenCv 3.0.0 需要重新编译

         并对相关文件进行修改，否则无法使用qt 4.8.6 进行编译。

OpenCV测试代码： 

 OpenCv_test.cpp 

       

/*

#include <video/video.hpp>

using namespace cv;

    VideoCapture cap(0);
    if(!cap.isOpened())
    {
        return -1;

    bool stop = false;
    while(!stop)
    {

        cvtColor(frame, edges, /*CV_BGR2RGB*/CV_BGR2BGRA ); // 0

        imshow("Camera",edges);
        if(waitKey(30) >=0)
            stop = true;
    }
    return 0;
