How to Play and Record UDP URL Video in WPF C#?

Question

I have to Play and Record UDP Url Video in my WPF Application, For that purpose currently I am using vlc.dotnet.wpf package

In Xaml side I have Assembly

xmlns:wpf="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"

Have Control to play Video

<wpf:VlcControl BorderBrush="White" BorderThickness="1" x:Name="vlcControl1" Grid.Column="0" Background="#FF023602" />

Code behind:

DirectoryInfo vlcLibDirectory = new DirectoryInfo(System.IO.Path.Combine(currentDirectory, "libvlc", IntPtr.Size == 4 ? "win-x86" : "win-x64"));
            this.vlcControl1.SourceProvider.CreatePlayer(this.vlcLibDirectory);
            vlcControl1.SourceProvider.MediaPlayer.Play(new Uri(@"udp://@127.0.0.1:5000"));

By this I'm Playing UDP Video Successfully, Now I want to record this Video to Specific Directory in my PC, Please guideme what I have to add in my code further to achieve this, Please recommend me any other tool/ Lib etc if it's not easy with vlc plugin. Thank You v Much

There is a libvlcsharp sample that does exactly this, here: https://github.com/mfkl/libvlcsharp-samples/blob/master/RecordHLS/Program.cs

Code:

using LibVLCSharp.Shared;
using System;
using System.IO;
using System.Reflection;

namespace RecordHLS
{
    class Program
    {
        static void Main(string[] args)
        {
            // Record in a file "record.ts" located in the bin folder next to the app
            var currentDirectory = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
            var destination = Path.Combine(currentDirectory, "record.ts");

            // Load native libvlc library
            Core.Initialize();

            using (var libvlc = new LibVLC())
            using (var mediaPlayer = new MediaPlayer(libvlc))
            {
                // Redirect log output to the console
                libvlc.Log += (sender, e) => Console.WriteLine($"[{e.Level}] {e.Module}:{e.Message}");
                mediaPlayer.EndReached += (sender, e) =>
                {
                    Console.WriteLine("Recorded file is located at " + destination);
                    Environment.Exit(0);
                };

                // Create new media with HLS link
                using (var media = new Media(libvlc, new Uri("http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4"),
                    // Define stream output options.
                    // In this case stream to a file with the given path and play locally the stream while streaming it.
                    ":sout=#file{dst=" + destination + "}", 
                    ":sout-keep"))
                {
                    // Start recording
                    mediaPlayer.Play(media);
                }

                Console.WriteLine($"Recording in {destination}");
                Console.WriteLine("Press any key to exit");
                Console.ReadKey();
            }
        }
    }
}

Please migrate to libvlcsharp instead of using vlc.dotnet. vlc.dotnet is unmaintained.

Alright, But how to play the video in the app as well? Now I'm using Control from LibVLCSharp.WPF for this purpose, but both recording and playing isn't working at the same time.. — Mr. Xek, Mar 21 '23 at 11:59
