我想将IplImage
(从视频文件抓取)存储到矢量中,然后从此iplimage
矢量播放。
#include <iostream>
#include "highgui.h"
using namespace std;
int main()
{
CvCapture* capture=cvCreateFileCapture("D:\\Video\\Hands tracking.avi");
vector<IplImage*> imagesNames[2];
//playing video
while(1)
{
IplImage* img=cvQueryFrame(capture);
cvShowImage("Video Opencv example nd testing purpose",img);
imagesNames[0].push_back(img);
char c = cvWaitKey(30);
if(c==27) break;
}
cvDestroyWindow( "Video Opencv example nd testing purpose" );
cvReleaseCapture(&capture);
// play back grabbed IplImages
for(unsigned i=0; imagesNames[0].size();i++)
{
cvShowImage("PlayBack from IplImages vector",imagesNames[0][i]);
char c = cvWaitKey(30);
if(c==27) break;
}
return 0;
}
但上述程序的播放部分无效并在运行时显示错误。
答案 0 :(得分:0)
