Method 1: LibVLCSharp.WinForms Implementation

LibVLCSharp offers a comperhensive wrapper for VLC media player capabilities in WinForms.

Required Packages

Install the LibVLCSharp.WinForms NuGet package and its associated native libraries.

Control Configurtaion

public class VlcStreamViewer : UserControl
{
    private LibVLC _mediaCore;
    private MediaPlayer _streamPlayer;
    private VideoView _videoOutput;

    public VlcStreamViewer()
    {
        if (!DesignMode)
        {
            Core.Initialize();
        }

        _mediaCore = new LibVLC();
        _streamPlayer = new MediaPlayer(_mediaCore)
        {
            Volume = 0,
            EnableHardwareDecoding = true
        };

        _videoOutput = new VideoView { Dock = DockStyle.Fill };
        _videoOutput.MediaPlayer = _streamPlayer;
        Controls.Add(_videoOutput);

        Load += Viewer_Load;
        Disposed += Viewer_Disposed;
    }

    private void Viewer_Load(object sender, EventArgs e)
    {
        DoubleBuffered = true;
    }

    private void Viewer_Disposed(object sender, EventArgs e)
    {
        _streamPlayer?.Stop();
        _streamPlayer?.Dispose();
        _mediaCore?.Dispose();
    }
}

Stream Initialization

public void ConnectStream(string url)
{
    var configOptions = new[]
    {
        "--no-audio",
        "--file-caching=300",
        "--live-caching=300",
        "--network-caching=333",
        "--avcodec-hw=any"
    };

    using (var media = new Media(_mediaCore, url, FromType.FromLocation, configOptions))
    {
        _streamPlayer.Play(media);
    }
}

Disconnection

public void DisconnectStream()
{
    if (_streamPlayer.IsPlaying)
    {
        _streamPlayer.Stop();
    }
}

Method 2: Emgu.CV Itnegration

Emgu.CV provides OpenCV bindings for real-time video capture and processing.

Required Packages

Add Emgu.CV.UI and Emgu.CV.runtime.windows to your project via NuGet.

Display Setup

public class CvStreamPanel : UserControl
{
    private ImageBox _previewBox;
    private VideoCapture _captureDevice;

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        
        _previewBox = new ImageBox 
        { 
            SizeMode = PictureBoxSizeMode.Zoom,
            Dock = DockStyle.Fill 
        };
        Controls.Add(_previewBox);
        DoubleBuffered = true;
    }
}

Capture and Display

public void StartCapture(string rtspAddress)
{
    _captureDevice = new VideoCapture(rtspAddress);
    _captureDevice.ImageGrabbed += ProcessFrame;
    _captureDevice.Start();
}

private void ProcessFrame(object sender, EventArgs e)
{
    using (var retrievedFrame = new Mat())
    {
        if (_captureDevice.Retrieve(retrievedFrame) && !retrievedFrame.IsEmpty)
        {
            var displayImage = retrievedFrame.Clone();
            Invoke(new Action(() => 
            {
                _previewBox.Image?.Dispose();
                _previewBox.Image = displayImage;
            }));
        }
    }
}

Capture Termination

public void StopCapture()
{
    if (_captureDevice != null)
    {
        _captureDevice.ImageGrabbed -= ProcessFrame;
        _captureDevice.Stop();
        _captureDevice.Dispose();
        _captureDevice = null;
    }
}
