谁能向我解释为什么下面的代码不起作用?
#include "opencv/cv.h"
#include "opencv/highgui.h"
#include <iostream>
int main(int, char**) {
cv::VideoCapture vcap;
cv::Mat image;
const std::string videoStreamAddress = "http://hg55.no-ip.org/mjpg/video.mjpg";
//Yes, this stream does work! Try to paste it into your browser...
//open the video stream and make sure it's opened
if(!vcap.open(videoStreamAddress)) {
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;
}
}
此代码确实无法打开流...
该代码基于此线程中的一些代码:OpenCV with Network Cameras
这里的 OpenCV 1 代码对我来说没有任何问题。
非常感谢您提前
