OpenCV를 사용하여 네트워크 카메라에서 프레임을 캡처하는 방법은 무엇입니까?

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

int main(int, char**) {
    cv::VideoCapture vcap;
    cv::Mat image;

    // TODO: Replace with appropriate stream address
    const std::string videoStreamAddress = "rtsp://cam_address:554/live.sdp"; 

    vcap.open(videoStreamAddress);
    if (!vcap.isOpened()) {
        std::cout << "Failed to open video stream." << std::endl;
        return -1;
    }

    cv::namedWindow("Output Window");

    while (true) {
        vcap >> image;
        if (image.empty()) {
            std::cout << "No frame available." << std::endl;
            cv::waitKey(0);
            continue;
        }

        cv::imshow("Output Window", image);
        if (cv::waitKey(1) >= 0) break;
    }

    return 0;
}
