int num = 1;
CvSize size = cvSize(1024,633);  //视频帧格式的大小
Mat image;
double fps = 4.0;
VideoWriter writer = VideoWriter("D:\\phei1.avi",CV_FOURCC('M','J','P','G'),fps,size);
char cname[100] = {0};
VideoCapture capture;
capture.open("D:\\phei1.avi");
while(1)
{
sprintf(cname,"D:\\potho\\img%d.jpg",num); //加载图片的文件夹，图片的名称编号是1开始

image = imread(cname,-1);//加载图片文件至内存
if (image.empty())
{
cout << "图像加载失败！" << endl;
return -1;
}
imshow("DisplayImage",image);
