C++ opencv 读取mp4文件

1.第一步：安装Xvid

2.第二步：安装ffdshow

3.看代码

#include "./opencv2.4.10/core.hpp"
#include "./opencv2.4.10/highgui.hpp"
#include "./opencv2.4.10/imgproc_c.h"
#include "./opencv2.4.10/mat.hpp"
using namespace std;

using namespace cv;

int main()

{

IplImage *frame = NULL;

CvCapture *capture = NULL;

capture = cvCreateFileCapture("test.mp4");

frame = cvQueryFrame(capture);

cvNamedWindow("frame");

while (frame){

cvShowImage("frame", frame);

cvWaitKey(20);

cout << "Frame Grabbed." << endl;

frame = cvQueryFrame(capture);

}

return 0;

}

第四步：将把opencv_ffmepg2410.dll放在根目录下就可以读取.
一切ok了。
