OpenCV学习（二）读取视频文件和摄像头

#include "highgui.h"

int main(int argc, char* argv[])

{

cvNamedWindow("avi"); //创建窗口

CvCapture* capture = cvCreateFileCapture(“视频文件路径"); //打开视频文件路径 //cvCreateCameraCapture //打开摄像头进行捕捉

IplImage* frame;

while(1)

{

frame = cvQueryFrame(capture); //加载视频文件

if(!frame)

break;

cvShowImage("avi",frame); //在窗口中显示视频文件

char c = cvWaitKey(33); //延时33毫秒

if(c==27)

break;

}

cvReleaseCapture(&capture); //释放内存

cvDestroyWindow("avi"); //销毁窗口

return 0;

}
