EmguCV捕获rtsp ip摄像机流ffmpeg

Question

I am working with IP camera and EmguCV to detect person in an area. Everything is work normally with Highgui capture source. But with Arlo camera which use FFMPEG format, I am unable to get stream without any exception. Here is the code I have tried:

if (capture == null)
        {
            try
            {
                capture = new Capture("rtsp://<IP>:8554/live"); 
                capture.ImageGrabbed += Capture_ImageGrabbed;
                capture.Grab();
                capture.Start();
            }


            catch (NullReferenceException exception)
            {
                MessageBox.Show(exception.Message);
            }
            catch (TypeInitializationException exc)
            {
                MessageBox.Show(
                   "Attention: You have to copy all the assemblies and native libraries from an official release of EmguCV to the directory of the demo." +
                   Environment.NewLine + Environment.NewLine + exc);
            }
}

and here is Capture_ImageGrabbed event which is not fired.

private void Capture_ImageGrabbed(object sender, EventArgs e)
    {
        Mat image = new Mat();
        capture.Retrieve(image);
        picCAM.Image = image.Bitmap;
    }

Thanks so much for your help!

This might be old, but until now I'm also facing the same issue, even using the newest version (which is version 3.3). Probably not the best solution, but after took some trial and error, what I did is to downgrade to version 2.4.2. You can download here .

I also recently submitted this issue in github . This is probably a bug.
