Drastic.YouTube

Drastic.YouTube is a fork of YoutubeExplode, designed for new features while keeping a similar-ish layout and API. There is no real plan for this, outside of adding new features for myself whenever I feel like it, but if there is interest in more active development of this then let me know.

License

Following the original library, Drastic.Youtube is licensed under LGPL3. Tyrrrz, the original developer, also included a clause regarding Russia's military aggression against Ukraine. I agree and stand by that and will be including it here:

(Drastic.YouTube) is a library that provides an interface to query metadata of YouTube videos, playlists and channels, as well as to resolve and download video streams and closed caption tracks. Behind a layer of abstraction, the library parses raw page content and uses reverse-engineered requests to retrieve information. As it doesn't rely on the official API, there's also no need for an API key and there are no usage quotas.

Install

  • πŸ“¦ : dotnet add package Drastic.YouTube

Usage

Drastic.YouTube exposes its functionality through a single entry point β€” the YoutubeClient class. Create an instance of this class and use the provided operations on Videos, Playlists, Channels, and Search properties to send requests.

Videos

Retrieving video metadata

To retrieve the metadata associated with a YouTube video, call Videos.GetAsync(...):

using Drastic.YouTube;

var youtube = new YoutubeClient();

// You can specify both video ID or URL
var video = await youtube.Videos.GetAsync("https://youtube.com/watch?v=u_yIGGhubZs");

var title = video.Title; // "Collections - Blender 2.80 Fundamentals"
var author = video.Author.ChannelTitle; // "Blender"
var duration = video.Duration; // 00:07:20
Downloading video streams

Every YouTube video has a number of streams available, differing in containers, video quality, bit rate, frame rate, and other properties. Additionally, depending on the content of the stream, the streams are further divided into 3 categories:

  • Muxed streams β€” contain both video and audio
  • Audio-only streams β€” contain only audio
  • Video-only streams β€” contain only video

You can request the manifest that lists all available streams for a particular video by calling Videos.Streams.GetManifestAsync(...):

using Drastic.YouTube;

var youtube = new YoutubeClient();

var streamManifest = await youtube.Videos.Streams.GetManifestAsync(
    "https://youtube.com/watch?v=u_yIGGhubZs"
);

Once you get the manifest, you can filter through the streams and select the ones you're interested in:

using Drastic.YouTube;
using Drastic.YouTube.Videos.Streams;

// ...

// Get highest quality muxed stream
var streamInfo = streamManifest.GetMuxedStreams().GetWithHighestVideoQuality();

// ...or highest bitrate audio-only stream
var streamInfo = streamManifest.GetAudioOnlyStreams().GetWithHighestBitrate();

// ...or highest quality MP4 video-only stream
var streamInfo = streamManifest
    .GetVideoOnlyStreams()
    .Where(s => s.Container == Container.Mp4)
    .GetWithHighestVideoQuality()

Finally, you can resolve the actual stream represented by the specified metadata using Videos.Streams.GetAsync(...) or download it directly to a file with Videos.Streams.DownloadAsync(...):

// ...

// Get the actual stream
var stream = await youtube.Videos.Streams.GetAsync(streamInfo);

// Download the stream to a file
await youtube.Videos.Streams.DownloadAsync(streamInfo, $"video.{streamInfo.Container}");

Warning: Muxed streams contain both audio and video, but these streams are very limited in quality (up to 720p30). To download video in the highest available quality, you need to resolve the best audio-only and video-only streams separately and then mux them together.

Downloading closed captions

Closed captions can be downloaded in a similar way to media streams. To get the list of available closed caption tracks, call Videos.ClosedCaptions.GetManifestAsync(...):

using Drastic.YouTube;

var youtube = new YoutubeClient();

var trackManifest = await youtube.Videos.ClosedCaptions.GetManifestAsync(
    "https://youtube.com/watch?v=u_yIGGhubZs"
);

Then retrieve the metadata for a particular track:

// ...

// Find closed caption track in English
var trackInfo = trackManifest.GetByLanguage("en");

Finally, use Videos.ClosedCaptions.GetAsync(...) to get the actual content of the track:

// ...

var track = await youtube.Videos.ClosedCaptions.GetAsync(trackInfo);

// Get the caption displayed at 0:35
var caption = track.GetByTime(TimeSpan.FromSeconds(35));
var text = caption.Text; // "collection acts as the parent collection"

You can also download the closed caption track in SRT file format with Videos.ClosedCaptions.DownloadAsync(...):

// ...

await youtube.Videos.ClosedCaptions.DownloadAsync(trackInfo, "cc_track.srt");

Playlists

Retrieving playlist metadata

You can get the metadata associated with a YouTube playlist by calling Playlists.GetAsync(...) method:

using Drastic.YouTube;

var youtube = new YoutubeClient();

var playlist = await youtube.Playlists.GetAsync(
    "https://youtube.com/playlist?list=PLa1F2ddGya_-UvuAqHAksYnB0qL9yWDO6"
);

var title = playlist.Title; // "First Steps - Blender 2.80 Fundamentals"
var author = playlist.Author.ChannelTitle; // "Blender"
Getting videos included in a playlist

To get the videos included in a playlist, call Playlists.GetVideosAsync(...):

using Drastic.YouTube;
using Drastic.YouTube.Common;

var youtube = new YoutubeClient();

// Get all playlist videos
var videos = await youtube.Playlists.GetVideosAsync(
    "https://youtube.com/playlist?list=PLa1F2ddGya_-UvuAqHAksYnB0qL9yWDO6"
);

// Get only the first 20 playlist videos
var videosSubset = await youtube.Playlists
    .GetVideosAsync(playlist.Id)
    .CollectAsync(20);

You can also enumerate the videos iteratively without waiting for the whole list to load:

using Drastic.YouTube;

var youtube = new YoutubeClient();

await foreach (var video in youtube.Playlists.GetVideosAsync(
    "https://youtube.com/playlist?list=PLa1F2ddGya_-UvuAqHAksYnB0qL9yWDO6"
))
{
    var title = video.Title;
    var author = video.Author;
}

If you need precise control over how many requests you send to YouTube, use Playlists.GetVideoBatchesAsync(...) which returns videos wrapped in batches:

using Drastic.YouTube;

var youtube = new YoutubeClient();

// Each batch corresponds to one request
await foreach (var batch in youtube.Playlists.GetVideoBatchesAsync(
    "https://youtube.com/playlist?list=PLa1F2ddGya_-UvuAqHAksYnB0qL9yWDO6"
))
{
    foreach (var video in batch.Items)
    {
        var title = video.Title;
        var author = video.Author;
    }
}

Channels

Retrieving channel metadata

You can get the metadata associated with a YouTube channel by calling Channels.GetAsync(...) method:

using Drastic.YouTube;

var youtube = new YoutubeClient();

var channel = await youtube.Channels.GetAsync(
    "https://youtube.com/channel/UCSMOQeBJ2RAnuFungnQOxLg"
);

var title = channel.Title; // "Blender"

You can also get the channel metadata by username with Channels.GetByUserAsync(...):

using Drastic.YouTube;

var youtube = new YoutubeClient();

var channel = await youtube.Channels.GetByUserAsync("https://youtube.com/user/BlenderFoundation");

var id = channel.Id; // "UCSMOQeBJ2RAnuFungnQOxLg"

To get the channel metadata by slug or custom URL, use Channels.GetBySlugAsync(...):

using Drastic.YouTube;

var youtube = new YoutubeClient();

var channel = await youtube.Channels.GetBySlugAsync("https://youtube.com/c/BlenderFoundation");

var id = channel.Id; // "UCSMOQeBJ2RAnuFungnQOxLg"
Getting channel uploads

To get a list of videos uploaded by a channel, call Channels.GetUploadsAsync(...):

using Drastic.YouTube;
using Drastic.YouTube.Common;

var youtube = new YoutubeClient();

var videos = await youtube.Channels.GetUploadsAsync(
    "https://youtube.com/channel/UCSMOQeBJ2RAnuFungnQOxLg"
);

Searching

You can execute a search query and get its results by calling Search.GetResultsAsync(...). Each result may represent either a video, a playlist, or a channel, so you need to apply pattern matching to handle the corresponding cases:

using Drastic.YouTube;

var youtube = new YoutubeClient();

await foreach (var result in youtube.Search.GetResultsAsync("blender tutorials"))
{
    // Use pattern matching to handle different results (videos, playlists, channels)
    switch (result)
    {
        case VideoSearchResult video:
        {
            var id = video.Id;
            var title = video.Title;
            var duration = video.Duration;
            break;
        }
        case PlaylistSearchResult playlist:
        {
            var id = playlist.Id;
            var title = playlist.Title;
            break;
        }
        case ChannelSearchResult channel:
        {
            var id = channel.Id;
            var title = channel.Title;
            break;
        }
    }
}

To limit results to a specific type, use Search.GetVideosAsync(...), Search.GetPlaylistsAsync(...), or Search.GetChannelsAsync(...):

using Drastic.YouTube;
using Drastic.YouTube.Common;

var youtube = new YoutubeClient();

var videos = await youtube.Search.GetVideosAsync("blender tutorials");
var playlists = await youtube.Search.GetPlaylistsAsync("blender tutorials");
var channels = await youtube.Search.GetChannelsAsync("blender tutorials");

Similarly to playlists, you can also enumerate results in batches by calling Search.GetResultBatchesAsync(...):

using Drastic.YouTube;

var youtube = new YoutubeClient();

// Each batch corresponds to one request
await foreach (var batch in youtube.Search.GetResultBatchesAsync("blender tutorials"))
{
    foreach (var result in batch.Items)
    {
        switch (result)
        {
            case VideoSearchResult videoResult:
            {
                // ...
            }
            case PlaylistSearchResult playlistResult:
            {
                // ...
            }
            case ChannelSearchResult channelResult:
            {
                // ...
            }
        }
    }
}
