Can't catch my IP Camera stream URL but other IP Camera stream URLs works

Question

I am using the below code successfully to stream the URL of a public IP web camera.

Now, I have set up my own IP Camera and I am now trying to catch this feed but are not successfull.
I am not sure if I should share the correct URL because it can be overload if everyone is checking.

However, - the exact format of the URL is this which works in Chrome where I can see the feed:
http://admin:[email protected]:1024/web/admin.html (not the real IP)

The feed in chrome looks like this which is the IP Camera software

I am then trying to catch ONLY the image stream itself with below code which I am not successful with. I have tried below with no success at all. Nothing appears in the image control:
http://admin:[email protected]:1024/web/admin.html
http://admin:[email protected]:1024
http://79.123.101.121:1024

As seen I add username and password which are: admin and admin which is needed to see the stream.

What could be the problem for this?

(I am using the library: "Emgu.CV" version v4.1.1.3497 which exist in the Nuget that can be installed)

        using Emgu.CV;
        using Emgu.CV.UI;
        using Emgu.CV.Structure;


        private VideoCapture _capture = null;
        private bool _captureInProgress;
        Emgu.CV.UI.ImageBox imageBox = new Emgu.CV.UI.ImageBox();
        public Form1()
        {
            InitializeComponent();

            imageBox.Width = 700;
            imageBox.Height = 500;
            panel19.Controls.Add(imageBox);
            CvInvoke.UseOpenCL = false;
            try
            {
                _capture = new VideoCapture("http://77.243.103.105:8081/mjpg/video.mjpg");
                _capture.ImageGrabbed += ProcessFrame;
            }
            catch (NullReferenceException excpt) { MessageBox.Show(excpt.Message); }
        }
        private void button1_Click(object sender, EventArgs e)
        {
            if (_capture == null)
            {
                try
                {
                    _capture = new VideoCapture();
                }
                catch (NullReferenceException excpt) { MessageBox.Show(excpt.Message); }
            }
            if (_capture != null)
            {
                if (_captureInProgress)
                {
                    button1.Text = "Start!"; //if camera is getting frames then stop the capture and set button Text "Start" for resuming capture
                    Application.Idle -= ProcessFrame;
                }
                else
                {
                    button1.Text = "Stop"; //if camera is NOT getting frames then start the capture and set button Text to "Stop" for pausing capture
                    Application.Idle += ProcessFrame;
                }
                _captureInProgress = !_captureInProgress;
            }
        }

        Mat frame = new Mat();
        private void ProcessFrame(object sender, EventArgs arg)
        {
            //_capture.Retrieve(frame, 0); //(1st try)
            _capture.Read(frame);  //This calls Grab() as grabbing a frame and then Retrieve(); (2nd try)
            imageBox.Image = frame;  //line 2
        }

EDIT: I used wireshark when I entered the IP Camera in Chrome browser to sniff what is going on. I have changed the IP in the below so not everyone is looking as I am developing on the camera:

This is the information I get:

GET /web/cgi-bin/hi3510/param.cgi?cmd=getvencattr&-chn=11&cmd=getvencattr&-chn=12&cmd=getsetupflag&cmd=getaudioflag&cmd=getrtmpattr HTTP/1.1

Then If I build an URL from above info like this:

http://79.129.110.182:1024/web/cgi-bin/hi3510/param.cgi?cmd=getvencattr&-chn=11&cmd=getvencattr&-chn=12&cmd=getsetupflag&cmd=getaudioflag&cmd=getrtmpattr

I get this result in chrome which actually are the settings for the IP Camera:

var bps_1="1536"; var fps_1="25"; var gop_1="50"; var brmode_1="1"; var imagegrade_1="4"; var width_1="1280"; var height_1="720"; var bps_2="448"; var fps_2="5"; var gop_2="50"; var brmode_2="1"; var imagegrade_2="2"; var width_2="640"; var height_2="352"; var name0="admin"; var password0="admin"; var authLevel0="15"; var audioflag="1"; var rtmpport="1935";

Answer 1

For newer cameras, try the following to get a stream:

• rtsp://default:@192.168.xx.xx:554/11
• http://default:@192.168.xx.xx/livestream.cgi?stream=2&action=play&media=video_audio_data

You can also make your own webpage and add a video canvas object, pass it as a parameter to libede265.js (found on camera, http://<your_ip>/js/libde265.js).

I'm also making a chrome extension to make this web interface better. Right now it's just fullscreen video and PTZ control via keyboard. Lots more to come.

I call it - "POS IP Cam" 
<head>
   <script src="<ip>/js/libde265.js" type="text/javascript"></script>

   <script type="text/javascript">
      window.addEventListener("load", function () {
       let ip = "<your_ip>";
       let httpport = "80";
       let stream = 11; //11 or 12
       let username = "<your_username>";
       let password = "<your_password>";

       let video_canvas = document.getElementById("video_canvas");
       player = new libde265.RawPlayer(video_canvas);
       player.playvideo(ip, httpport, stream, username, password);
     });


   </script>
