🔥 Quick Start

1️⃣ Retrieve Video Metadata

IYouTubeMetadataService downloader = new YouTubeMetadataService(new YoutubeClient());
var video = await downloader.GetVideoInfoAsync(TEST_VIDEO_URL);

Console.WriteLine($"Title: {video.Title}");
Console.WriteLine($"Duration: {video.Duration}");

IYouTubeMetadataService downloader = new YouTubeMetadataService(new YoutubeClient());
var outputPath = "C:\\Videos";
string filePath = await downloader.DownloadVideoAsFileAsync(TEST_VIDEO_URL, outputPath);
Console.WriteLine($"Video downloaded successfully: {filePath}");

3️⃣ Fetch All Playlists from a Channel

using Microsoft.Extensions.DependencyInjection;
using YouTubeStreamDownloader.Services;

var services = new ServiceCollection();
services.AddYouTubeMetadataService();
var provider = services.BuildServiceProvider();

var metadataService = provider.GetRequiredService<IYouTubeMetadataService>();

var playlists = await metadataService.GetAllPlaylistsAsync("https://www.youtube.com/@YourChannel");

foreach (var playlist in playlists)
{
    Console.WriteLine($"{playlist.Title}: {playlist.Url}");
}

4️⃣ Fetch All Videos from a Playlist

using Microsoft.Extensions.DependencyInjection;
using YouTubeStreamDownloader.Services;

var provider = new ServiceCollection()
    .AddYouTubeMetadataService()
    .BuildServiceProvider();

var metadataService = provider.GetRequiredService<IYouTubeMetadataService>();

var videos = await metadataService.GetAllVideosFromPlaylistAsync("https://www.youtube.com/playlist?list=YOUR_PLAYLIST_ID");

foreach (var video in videos)
{
    Console.WriteLine($"{video.Title}: {video.Url}");
}

🏗 Dependency Injection (DI)

To use YouTubeStreamDownloader in an ASP.NET Core or Console Application, register it in Program.cs:

using Microsoft.Extensions.DependencyInjection;
using YouTubeStreamDownloader.Services;

var builder = WebApplication.CreateBuilder(args);

// Register the service
builder.Services.AddYouTubeMetadataService();

var app = builder.Build();

For Singleton DI:

builder.Services.AddYouTubeMetadataSingletonService();
