Question

我想在Microsoft Visual Studio中使用opencv 2.45使用我的Dynacolor IP摄像头拍照。

我用iSpy找到了它的ip。这是我的代码。

#include "opencv2/highgui/highgui.hpp"
#include "opencv2/core/core.hpp"
#include "opencv2/opencv.hpp"

int main()
{
    cv::VideoCapture vcap;
    const std::string videoStreamAddress = "http://Admin:1234@192.168.0.250:80/cgi-bin/jpg/image.cgi";
    if (!vcap.open(videoStreamAddress))
    {
        printf("Camera is null\n");
        return -1;
    }
    else
    {
        cv::Mat image;
        vcap.read(image);
        cv::imshow("image",image);
    }
    cv::waitKey(100);
    return 0
}

这给我一个警告：找不到编解码器参数＆lt; ... / ... / modules / highgui / src / cap_ffmpeg_impl.hpp：540＆gt ;,而且Camera也为空。

我已经阅读了很多有关此问题的主题，但我无法解决这个问题。

任何帮助都将不胜感激。

检查此代码。这个对我有用。请注意地址末尾的“？.mjpg”。我也改变了IP和端口进行测试。

使用opencv连接到IP摄像头
