//  C# class that uses the VLC library to record a video stream:



using System;
using System.IO;
using Vlc.DotNet.Core;
using Vlc.DotNet.Core.Interops;
using Vlc.DotNet.Core.Interops.Signatures.LibVlc.MediaPlayer;

namespace VideoRecorder
{
    public class VlcVideoRecorder
    {
        private VlcMediaPlayer _player;
        private VlcMedia _media;

        public void StartRecording(string streamUrl, string outputFilePath)
        {
            var vlcOptions = new string[]
            {
                "--no-audio",      // Disable audio recording
                "--sout=#transcode{vcodec=h264,vb=2000,fps=30}:file{dst=" + outputFilePath + "}" // Transcode and save to file
            };

            // Initialize VLC library
            VlcContext.LibVlcAddOption(vlcOptions);
            VlcContext.Initialize();

            // Create media player and media objects
            _player = new VlcMediaPlayer(VlcContext);
            _media = new VlcMedia(VlcContext, streamUrl, FromType.FromLocation);

            // Set media options
            _media.AddOption(":network-caching=1000");  // Increase network caching to prevent stuttering

            // Attach media to player and start playing
            _player.SetMedia(_media);
            _player.Play();
        }

        public void StopRecording()
        {
            // Stop recording and release resources
            _player.Stop();
            _media.Dispose();
            _player.Dispose();
            VlcContext.CloseAll();
        }
    }
}


/*
To use this class, you can call the StartRecording method with
the URL of the video stream you want to record and the file path
where you want to save the recorded video. For example:
*/


var recorder = new VlcVideoRecorder();
recorder.StartRecording("http://example.com/stream", "output.mp4");

// Wait for some time while recording...
System.Threading.Thread.Sleep(5000);

recorder.StopRecording();


/*
This will start recording the video stream and save it to a file
called "output.mp4". You can adjust the recording options by modifying
the vlcOptions array in the StartRecording method. For example, you can
change the video codec, bitrate, or frame rate by modifying the vcodec,
vb, or fps options, respectively.
