Thank you.

#include "opencv2/opencv.hpp"
#include <iostream>

using namespace std;
using namespace cv;

int main() {

    VideoCapture vcap(0);
    if (!vcap.isOpened()) {
        cout << "Error opening video stream or file" << endl;
        return -1;
    }

    int frame_width = vcap.get(CV_CAP_PROP_FRAME_WIDTH);
    int frame_height = vcap.get(CV_CAP_PROP_FRAME_HEIGHT);
    VideoWriter video("/MyVideo.avi", CV_FOURCC('M', 'J', 'P', 'G'), 10, Size(frame_width, frame_height), true);

    for (;;) {

        Mat frame;
        vcap >> frame;
        video.write(frame);
        imshow("Frame", frame);
        char c = (char)waitKey(33);
        if (c == 27) break;
    }
    return 0;
}
