我正在尝试显示来自网络摄像机的视频,但当我声明摄像机 ulr 时,程序显示错误的数组新长度。
#include <stdio.h>
#include <iostream>
#include <opencv2/opencv.hpp>
int main(int, char**) {
cv::VideoCapture vcap;
cv::Mat image;
// This works on a D-Link CDS-932Lrtsp://<Admin:mmcc2019>@10.5.1.101/
const std::string videoSt = "http://192.168.226.101:8080/video?x.mjpeg";
std::cout <<"lenght og the cmera ulr is" <<videoSt.length() << std::endl;
//open the video stream and make sure it's opened
if (!vcap.open(videoSt)) {
std::cout << "Error opening video stream or file" << std::endl;
return -1;
}
for (;;) {
if (!vcap.read(image)) {
std::cout << "No frame" << std::endl;
cv::waitKey();
}
cv::imshow("Output Window", image);
if (cv::waitKey(1) >= 0) break;
}
}
