将视频读取成帧图像的c++程序

#include "cv.h" #include "highgui.h" int main() { CvCapture *capture = cvCaptureFromAVI("V3.avi"); IplImage *img = 0; img =cvQueryFrame(capture); int i = 0; char name[100] = {}; while (img) { printf("%d\n", i); cvShowImage("dong",img); cvWaitKey(2); sprintf(name,"1\\%d.bmp",i++); cvSaveImage(name, img); img =cvQueryFrame(capture); } return 0; }
