Summary of your issue

When I use local video , it will succeed . But use IPcam(RTSP)doesn't work and and no error message is displayed.

Do I do anything wrong? I also use the same code in Python , it susucceed.

Environment

VisualStudio c# .NETFramework4.8 WPF .

What did you do when you faced the problem?

Write here

Example code:

using System;
using OpenCvSharp;
using OpenCvSharp.Extensions;

private void BtPlay_Click(object sender, RoutedEventArgs e)
{
            VideoCapture capVideo = null;
            const int cameraWidth = 3840;
            const int cameraHeight = 2160;
            capVideo = new VideoCapture("rtsp://admin:123456qwer!@192.168.1.13:554/media/video1");

            Console.WriteLine(Cv2.GetBuildInformation());
            bool flag=capVideo.IsOpened();
            if (!flag)
            {
                MessageBox.Show("no input");
            }
}

Output:

Cv2.GetBuildInformation();
