opencv重复循环播放视频

Posted 2023-05-15

参考技术A string filename = "video4.mp4"; // File name

VideoCapture capture(filename);

if (!capture.isOpened())

cout << "fail to open!" << endl;

int frame_cnt = capture.get(CV_CAP_PROP_FRAME_COUNT);

Mat source, source2, source1, destination;

while (true)

        if(capture.get(CV_CAP_PROP_POS_FRAMES) == frame_cnt)

            capture.set(CV_CAP_PROP_POS_FRAMES, 0);

       

        capture.read(source2);//capture >> source2;
