通过 RTSP 流式传输 opencv 视频

Question

有谁知道我可以捕获 RTSP 流以使用 rtsp 视频源测试视频捕获的链接？我已经尝试过使用 USB cam 和网络摄像头，但我想使用 RTSP 流对其进行测试。

这里是来源：

#include "opencv2/highgui/highgui.hpp"
#include <iostream>

using namespace cv;
using namespace std;

int main(int argc, char* argv[])
{
    VideoCapture cap("rtsp:\\ANYTHING,PLEASE"); // open the video file for reading

    if ( !cap.isOpened() )  // if not success, exit program
    {
         cout << "Cannot open the video file" << endl;
         return -1;
    }

    //cap.set(CV_CAP_PROP_POS_MSEC, 300); //start the video at 300ms

    double fps = cap.get(CV_CAP_PROP_FPS); //get the frames per seconds of the video

     cout << "Frame per seconds : " << fps << endl;

    namedWindow("MyVideo",CV_WINDOW_AUTOSIZE); //create a window called "MyVideo"

    while(1)
    {
        Mat frame;

        bool bSuccess = cap.read(frame); // read a new frame from video

         if (!bSuccess) //if not success, break loop
        {
                        cout << "Cannot read the frame from video file" << endl;
                       break;
        }

        imshow("MyVideo", frame); //show the frame in "MyVideo" window

        if(waitKey(30) == 27) //wait for 'esc' key press for 30 ms. If 'esc' key is pressed, break loop
       {
                cout << "esc key is pressed by user" << endl; 
                break; 
       }
    }

    return 0;

}

您可以简单地使用 Videolan VLC 生成 RTSP 流。
媒体/流/添加任何视频文件/流/RTSP 添加/端口和路径/视频 H.264 + MP3 (MP4)/流。
然后你会得到一个像 rtsp://127.0.0.1:8554/vid 这样的视频流。当然，您可以使用 VLC 或 OpenCV 读取该流。
