一.读取并播放的代码如下：
#include "pch.h"
#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include<opencv2/imgproc/imgproc.hpp>
using namespace cv;
int main()
{
VideoCapture a;
a.open("C://Users//lenovo//Desktop//geeksong.mp4");
while (1)
{
Mat frame;
a >> frame;
imshow("读取视频", frame);
waitKey(600);
}
return 0;
}
二.获取摄像头里的视频，只需要将读取视频的路径改为0就可以了：
#include "pch.h"
#include <iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include<opencv2/imgproc/imgproc.hpp>
using namespace cv;
int main()
{
VideoCapture a;
a.open(0);
while (1)
{
Mat frame;
a >> frame;
imshow("读取视频", frame);
waitKey(600);
}
return 0;
}
实战深度学习OpenCV(二)：读取并播放本地或者摄像头的视频
