使用openCV读取摄像头或者视频非常方便，废话不多说，下面直接把源代码贴出来。

#include <stdio.h>
#include <highgui.h>
#include <cv.h>

int main(int argc, char * argv[])
{
	IplImage* frame = NULL;
	cvNamedWindow("vedio");

	//CvCapture* capture = cvCreateFileCapture("E:\\Videos\\shouji\\MOV0061A.avi");

	CvCapture* capture = cvCreateCameraCapture(1);
	assert(NULL!=capture);

	while(1)
	{
		frame = cvQueryFrame(capture);
		if(!frame)
		{
			break;
		}
		
		cvShowImage("vedio",frame);

		if(27==cvWaitKey(33))
		{
			break;
		}

	}
	cvReleaseCapture(&capture);
	cvDestroyWindow("vedio");

	return 0;
	
}
