## Quick Start

### 1. Discover and Connect to Chromecast

```csharp
using Sharpcaster;
using Sharpcaster.Models;
using Sharpcaster.Models.Media;

// Discover Chromecast devices
var locator = new ChromecastLocator();
var cancellationToken = new CancellationTokenSource(TimeSpan.FromSeconds(5)).Token;
var chromecasts = await locator.FindReceiversAsync(cancellationToken);

if (!chromecasts.Any())
{
    Console.WriteLine("No Chromecast devices found");
    return;
}

// Connect to first found device
var chromecast = chromecasts.First();
var client = new ChromecastClient();
await client.ConnectChromecast(chromecast);
Console.WriteLine($"Connected to {chromecast.Name}");
```

### 2. Launch Application and Play Media

```csharp
// Launch the default media receiver app
await client.LaunchApplicationAsync("CC1AD845"); // Default Media Receiver

// Create and load media
var media = new Media
{
    ContentUrl = "https://commondatastorage.googleapis.com/gtv-videos-bucket/CastVideos/mp4/DesigningForGoogleCast.mp4",
    ContentType = "video/mp4",
    Metadata = new MediaMetadata
    {
        Title = "Sample Video",
        SubTitle = "A demonstration video"
    }
};

var mediaStatus = await client.MediaChannel.LoadAsync(media);
Console.WriteLine($"Media loaded: {mediaStatus.PlayerState}");
```

## Comprehensive Examples

### Complete Media Player Example

```csharp
public class ChromecastMediaPlayer
{
    private ChromecastClient _client;
    private ChromecastReceiver _device;

public async Task<bool> ConnectAsync(string deviceName = null)
    {
        try
        {
            var locator = new ChromecastLocator();
            var devices = await locator.FindReceiversAsync(CancellationToken.None);
            
            _device = deviceName != null 
                ? devices.FirstOrDefault(d => d.Name.Contains(deviceName))
                : devices.FirstOrDefault();

if (_device == null) return false;

_client = new ChromecastClient();
            await _client.ConnectChromecast(_device);
            
            // Subscribe to events
            _client.MediaChannel.StatusChanged += OnMediaStatusChanged;
            _client.Disconnected += OnDisconnected;
            
            return true;
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Connection failed: {ex.Message}");
            return false;
        }
    }

public async Task PlayVideoAsync(string url, string title = null)
    {
        await _client.LaunchApplicationAsync("CC1AD845"); // Default Media Receiver
        
        var media = new Media
        {
            ContentUrl = url,
            ContentType = GetContentType(url),
            Metadata = new MediaMetadata
            {
                Title = title ?? Path.GetFileNameWithoutExtension(url),
                MetadataType = MetadataType.Movie
            }
        };

await _client.MediaChannel.LoadAsync(media);
    }

public async Task PlayAudioAsync(string url, string title = null, string artist = null)
    {
        await _client.LaunchApplicationAsync("CC1AD845");
        
        var media = new Media
        {
            ContentUrl = url,
            ContentType = GetContentType(url),
            Metadata = new MusicTrackMetadata
            {
                Title = title ?? Path.GetFileNameWithoutExtension(url),
                Artist = artist,
                MetadataType = MetadataType.MusicTrack
            }
        };

await _client.MediaChannel.LoadAsync(media);
    }

private void OnMediaStatusChanged(object sender, MediaStatus status)
    {
        Console.WriteLine($"Media Status: {status.PlayerState} - {status.CurrentTime:F1}s");
    }

private void OnDisconnected(object sender, EventArgs e)
    {
        Console.WriteLine("Disconnected from Chromecast");
    }

private static string GetContentType(string url)
    {
        var extension = Path.GetExtension(url).ToLower();
        return extension switch
        {
            ".mp4" => "video/mp4",
            ".mp3" => "audio/mpeg",
            ".wav" => "audio/wav",
            ".webm" => "video/webm",
            _ => "video/mp4"
        };
    }
}
```

## Media Queue Management

SharpCaster supports advanced queue operations for playlist-style media playback:

```csharp
// Create a media queue
var queueItems = new[]
{
    new QueueItem
    {
        Media = new Media
        {
            ContentUrl = "https://example.com/song1.mp3",
            ContentType = "audio/mpeg",
            Metadata = new MusicTrackMetadata { Title = "Song 1", Artist = "Artist 1" }
        }
    },
    new QueueItem
    {
        Media = new Media
        {
            ContentUrl = "https://example.com/song2.mp3", 
            ContentType = "audio/mpeg",
            Metadata = new MusicTrackMetadata { Title = "Song 2", Artist = "Artist 2" }
        }
    }
};

// Load queue with repeat mode
await client.MediaChannel.QueueLoadAsync(queueItems, 0, RepeatModeType.ALL);

// Navigate through queue
await client.MediaChannel.QueueNextAsync();  // Next track
await client.MediaChannel.QueuePrevAsync();  // Previous track

// Get queue information
var itemIds = await client.MediaChannel.QueueGetItemIdsAsync();
var items = await client.MediaChannel.QueueGetItemsAsync(itemIds);
```

## Volume Control

```csharp
// Get current volume
var status = await client.ReceiverChannel.GetChromecastStatusAsync();
Console.WriteLine($"Current volume: {status.Volume.Level:P0}");

// Set volume (0.0 to 1.0)
await client.ReceiverChannel.SetVolumeAsync(0.5f);

// Mute/unmute
await client.ReceiverChannel.SetMutedAsync(true);
await client.ReceiverChannel.SetMutedAsync(false);
```

## Event Handling

SharpCaster provides rich event support for real-time updates:

```csharp
// Media events
client.MediaChannel.StatusChanged += (sender, status) =>
{
    Console.WriteLine($"Player State: {status.PlayerState}");
    Console.WriteLine($"Current Time: {status.CurrentTime}s");
    Console.WriteLine($"Duration: {status.Media?.Duration}s");
};

// Connection events  
client.Disconnected += (sender, args) =>
{
    Console.WriteLine("Connection lost to Chromecast");
};

// Application events
client.ReceiverChannel.StatusChanged += (sender, status) =>
{
    foreach (var app in status.Applications ?? [])
    {
        Console.WriteLine($"Running app: {app.DisplayName} ({app.AppId})");
    }
};
```

## Custom Chromecast Channels

Create custom channels for specialized applications:

```csharp
public class CustomGameChannel : ChromecastChannel
{
    public CustomGameChannel(ILogger<CustomGameChannel> logger) 
        : base("custom.game", logger) { }

public async Task SendGameCommandAsync(string command, object data)
    {
        var message = new { type = command, data = data };
        await SendAsync(JsonSerializer.Serialize(message));
    }

protected override async Task OnMessageReceivedAsync(string message, string messageType)
    {
        // Handle custom game messages
        var gameMessage = JsonSerializer.Deserialize<GameMessage>(message);
        // Process game-specific logic
    }
}

// Register and use custom channel
var gameChannel = new CustomGameChannel(logger);
client.RegisterChannel(gameChannel);
```

You can also reverse engineer existing channels:

1. In Chrome, go to `chrome://net-export/`
2. Select 'Include raw bytes (will include cookies and credentials)'
3. Click 'Start Logging to Disk'
4. Cast from your favorite web app
5. Stop logging and open the log in [netlog-viewer](https://netlog-viewer.appspot.com/)
6. Search for `type:SOCKET` and find familiar JSON data
7. Collect the exchanged JSON
8. Create a new class inheriting from `ChromecastChannel` and implement your logic

## Troubleshooting

### Common Issues and Solutions

**Device Discovery Issues:**
```csharp
// Increase discovery timeout for slow networks
var cancellationToken = new CancellationTokenSource(TimeSpan.FromSeconds(10)).Token;
var devices = await locator.FindReceiversAsync(cancellationToken);

// Manually specify device if discovery fails
var manualDevice = new ChromecastReceiver
{
    Name = "My Chromecast",
    DeviceUri = new Uri("http://192.168.1.100"),
    Port = 8009
};
```

**Connection Timeouts:**
```csharp
// Enable logging for debugging
var loggerFactory = LoggerFactory.Create(builder => 
    builder.AddConsole().SetMinimumLevel(LogLevel.Debug));
    
var client = new ChromecastClient(loggerFactory);
```

**Media Loading Failures:**
- Ensure media URLs are publicly accessible
- Verify correct `ContentType` is specified
- Check that the Chromecast supports the media format
- Use HTTPS URLs when possible

**Network Issues:**
- Ensure device is on the same network as Chromecast
- Check firewall settings (port 8009 must be accessible)
- Verify mDNS/Bonjour is enabled on the network

### Error Handling Best Practices

```csharp
try
{
    await client.MediaChannel.LoadAsync(media);
}
catch (TimeoutException)
{
    Console.WriteLine("Request timed out - check network connection");
}
catch (InvalidOperationException ex)
{
    Console.WriteLine($"Invalid operation: {ex.Message}");
}
catch (Exception ex)
{
    Console.WriteLine($"Unexpected error: {ex.Message}");
}
```
