MJPEG 网络流到 OpenCV 2
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相机
这里的 OpenCV 1 代码对我来说没有任何问题。
预先非常感谢
Can anyone explain to me why this code below does not work?
#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;
}
}
This code does cannot open the stream...
The code is based on some code in this thread: OpenCV with Network Cameras
The OpenCV 1 code here works without any problem for me.
Thank you very much in advance

我尝试使用 Visual Studio 2010 和 OpenCV 2.2 创建一个新项目，而不是 OpenCV 2.3.1。
这解决了我所有的问题！
