youtube-source

A rewritten YouTube source manager for Lavaplayer.

This source aims to provide robustness by leveraging multiple InnerTube clients for requests. Where one client fails, another will try to load the request. Which clients are used is entirely configurable.

common

This module provides the base source manager, which can be used with any com.sedmelluq.discord.lavaplayer packages still on major version 1.

Using in Gradle:

repositories {
  // replace with https://maven.lavalink.dev/snapshots if you want to use a snapshot version.
  maven(url = "https://maven.lavalink.dev/releases")
}

dependencies {
  // Replace VERSION with the current version as shown by the Releases tab or a long commit hash `-SNAPSHOT` for snapshots.
  implementation("dev.lavalink.youtube:common:VERSION")
}

Example usage:

YoutubeAudioSourceManager youtube = new YoutubeAudioSourceManager();
// Optionally, you may instantiate the source with a custom options, such as toggling use of searching, and clients.
YoutubeAudioSourceManager youtube = new YoutubeAudioSourceManager(/*allowSearch:*/ true, new Client[] { new Music(), new Web(), new AndroidTestsuite() });

You may also extend the Client interface to support additional InnerTube clients. There are a few abstract classes to make this easier, notably, MusicClient (for music.youtube.com InnerTube clients), NonMusicClient (for youtube.com innertube clients) and StreamingNonMusicClient (for clients that can be used to stream videos).

Support for IP rotation has been included, and can be achieved using the following:

AbstractRoutePlanner routePlanner = new ...
YoutubeIpRotatorSetup rotator = new YoutubeIpRotatorSetup(routePlanner);

// 'youtube' is the variable holding your YoutubeAudioSourceManager instance.
rotator.forConfiguration(youtube.getHttpInterfaceManager(), false)
    .withMainDelegateFilter(youtube.getContextFilter()) // IMPORTANT
    .setup();

v2

This modules expands on common by providing additional support for Lavaplayer 2.x clients, such as Lavalink-Devs/Lavaplayer. Such features currently include thumbnail support within AudioTrackInfo. Additional clients are included that provide access to this additional information. These clients are suffixed with Thumbnail, such as WebWithThumbnail, AndroidWithThumbnail etc.

Using in Gradle:

repositories {
  // replace with https://maven.lavalink.dev/snapshots if you want to use a snapshot version.
  maven(url = "https://maven.lavalink.dev/releases")
}

dependencies {
  // Replace VERSION with the current version as shown by the Releases tab or a long commit hash `-SNAPSHOT` for snapshots.
  implementation("dev.lavalink.youtube:v2:VERSION")
}

Example usage:

// same as the 'common' module but there are additional clients that provide video thumbnails in the returned metadata.
YoutubeAudioSourceManager youtube = new YoutubeAudioSourceManager(/*allowSearch:*/ true, new Client[] { new MusicWithThumbnail(), new WebWithThumbnail(), new AndroidTestsuiteWithThumbnail() });

plugin

This module serves as the plugin for use with Lavalink.

To use this plugin with Lavalink, you must declare the dependency.

Using with Lavalink v3:

lavalink:
  plugins:
    # Replace VERSION with the current version as shown by the Releases tab or a long commit hash for snapshots.
    - dependency: "dev.lavalink.youtube:youtube-plugin:VERSION"
      repository: "https://maven.lavalink.dev/releases" # use https://maven.lavalink.dev/snapshots if you want to use a snapshot version.

Using with Lavalink v4:

lavalink:
  plugins:
    # Replace VERSION with the current version as shown by the Releases tab or a long commit hash for snapshots.
    - dependency: "dev.lavalink.youtube:youtube-plugin:VERSION"
      snapshot: false # Set to true if you want to use a snapshot version.

Configuring the plugin:

Important

You must make sure to disable the built-in YouTube source like so:

lavalink:
  server:
    sources:
      youtube: false

Note

Existing options, such as ratelimit and youtubePlaylistLoadLimit will be picked up automatically by the plugin, so these don't need changing.

plugins:
  youtube:
    enabled: true # Whether this source can be used.
    allowSearch: true # Whether "ytsearch:" and "ytmsearch:" can be used.
    allowDirectVideoIds: true # Whether just video IDs can match. If false, only complete URLs will be loaded.
    allowDirectPlaylistIds: true # Whether just playlist IDs can match. If false, only complete URLs will be loaded.
    # The clients to use for track loading. See below for a list of valid clients.
    # Clients are queried in the order they are given (so the first client is queried first and so on...)
    clients:
      - MUSIC
      - ANDROID_VR
      - WEB
      - WEBEMBEDDED

Advanced Options

    # The below section of the config allows setting specific options for each client, such as the requests they will handle.
    # If an option, or client, is unspecified, then the default option value/client values will be used instead.
    # If a client is configured, but is not registered above, the options for that client will be ignored.
    # WARNING!: THE BELOW CONFIG IS FOR ILLUSTRATION PURPOSES. DO NOT COPY OR USE THIS WITHOUT
    # WARNING!: UNDERSTANDING WHAT IT DOES. MISCONFIGURATION WILL HINDER YOUTUBE-SOURCE'S ABILITY TO WORK PROPERLY.

    # Write the names of clients as they are specified under the heading "Available Clients".
    clientOptions:
      WEB:
        # Example: Disabling a client's playback capabilities.
        playback: false
        videoLoading: false # Disables loading of videos for this client. A client may still be used for playback even if this is set to 'false'.
      WEBEMBEDDED:
        # Example: Configuring a client to exclusively be used for video loading and playback.
        playlistLoading: false # Disables loading of playlists and mixes.
        searching: false # Disables the ability to search for videos.

Using OAuth Tokens

You may notice that some requests are flagged by YouTube, causing an error message asking you to sign in to confirm you're not a bot. With OAuth integration, you can request that youtube-source use your account credentials to appear as a normal user, with varying degrees of efficacy. You do not need to use poToken with OAuth.

Warning

Similar to the poToken method, this is NOT a silver bullet solution, and worst case could get your account terminated! For this reason, it is advised that you use burner accounts and NOT your primary!. This method may also trigger ratelimit errors if used in a high traffic environment. USE WITH CAUTION!

Note

You may need to set your log level for dev.lavalink.youtube.http.YoutubeOauth2Handler to INFO, to see additional information within your terminal regarding completing the OAuth flow.

Note

If you do not have a refresh token, then do not supply one. The source will output your refresh token into your terminal upon successfully completing the OAuth flow at least once. If you do not see your token, you may need to configure your logging (see above note).

You can instruct youtube-source to use OAuth with the following:

Lavaplayer

YoutubeAudioSourceManager source = new YoutubeAudioSourceManager();
// This will trigger an OAuth flow, where you will be instructed to head to YouTube's OAuth page and input a code.
// This is safe, as it only uses YouTube's official OAuth flow. No tokens are seen or stored by us.
source.useOauth2(null, false);

// If you already have a refresh token, you can instruct the source to use it, skipping the OAuth flow entirely.
// You can also set the `skipInitialization` parameter, which skips the OAuth flow. This should only be used
// if you intend to supply a refresh token later on. You **must** either complete the OAuth flow or supply
// a refresh token for OAuth integration to work.
source.useOauth2("your refresh token", true);

Lavalink

plugins:
  youtube:
    enabled: true
    oauth:
      # setting "enabled: true" is the bare minimum to get OAuth working.
      enabled: true

      # if you have a refresh token, you may set it below (make sure to uncomment the line to apply it).
      # setting a valid refresh token will skip the OAuth flow entirely. See above note on how to retrieve
      # your refreshToken.
      # refreshToken: "paste your refresh token here if applicable"

      # Set this if you don't want the OAuth flow to be triggered, if you intend to supply a refresh token later.
      # Initialization is skipped automatically if a valid refresh token is supplied. Leave this commented if you're
      # completing the OAuth flow for the first time/do not have a refresh token.
      # skipInitialization: true

Using a `poToken`

A poToken, also known as a "Proof of Origin Token" is a way to identify what requests originate from. In YouTube's case, this is sent as a JavaScript challenge that browsers must evaluate, and send back the resolved string. Typically, this challenge would remain unsolved for bots as more often than not, they don't simulate an entire browser environment, instead only evaluating the minimum amount of JS required to do its job. Therefore, it's a reasonable assumption that if the challenge is not fulfilled, the request origin is a bot.

To obtain a poToken, you can use https://github.com/iv-org/youtube-trusted-session-generator, by running the Python script or the docker image. Both methods will print a poToken after a successful run, which you can supply to youtube-source to try and work around having automated requests blocked.

Note

A poToken is not a silver bullet, and currently it only applies to requests made via the WEB client. You do not need to specify a poToken if using OAuth, and vice versa.

Specifying the token is as simple as doing:

Lavaplayer

// Web is dev.lavalink.youtube.clients.Web
Web.setPoTokenAndVisitorData("your po_token", "your visitor_data");

Lavalink

plugins:
  youtube:
    pot:
      token: "paste your po_token here"
      visitorData: "paste your visitor_data here"

REST routes (`plugin` only)

`POST` `/youtube`

Body:

Note

You do not need to provide everything as it is shown. For example, you can specify just refreshToken and skipInitialization, or just poToken and visitorData. You do not need to use poToken with OAuth and vice versa.

{
  "refreshToken": "your new refresh token",
  "skipInitialization": true,
  "poToken": "your po_token",
  "visitorData": "your visitor_data"
}

Response:

If the YouTube source is not enabled, or the refreshToken is invalid: 500 - Internal Server Error

Otherwise: 204 - No Content

`GET` `/youtube`

Response:

If the YouTube source is not enabled: 500 - Internal Server Error

Otherwise:

{
  "refreshToken": "your current refresh token, or null"
}

`GET` `/youtube/stream/{videoId}`

Query parameters:

Key	Value Type	Required	Notes
itag	integer	No	The itag of the desired format. If unspecified, youtube-source's default format selector will be used.
withClient	string	No	The identifier of the client to use for streaming. Uses all clients if unspecified.

Response:

If videoId could not be found or loaded, or the itag does not exist, or if no client supports format loading: 400 - Bad Request

Otherwise: 200 - OK accompanied by the selected format stream (audio or video). Content-Type header will be set appropriately.

Migration from Lavaplayer's built-in YouTube source

This client is intended as a direct replacement for Lavaplayer's built-in YoutubeAudioSourceManager, which has been deprecated in a recent release of Lavalink-Devs/Lavaplayer.

When using AudioSourceManagers.registerRemoteSources(AudioPlayerManager), Lavaplayer will register its own deprecated YoutubeAudioSourceManager, which must be disabled. Some versions of Lavaplayer may include an optional excludeSources parameter, allowing you to toggle the adding of the source. If the version you are using does not support this, you will need to manually register each AudioSourceManager yourself.

First, create and register an instance of the supported YoutubeAudioSourceManager from the youtube-source package.

AudioPlayerManager playerManager = new DefaultAudioPlayerManager();
YoutubeAudioSourceManager ytSourceManager = new dev.lavalink.youtube.YoutubeAudioSourceManager();
playerManager.registerSourceManager(ytSourceManager);

If your version of Lavaplayer supports an excludeSources parameter or equivalent, you may exclude the built-in YoutubeAudioSourceManager using the following:

AudioSourceManagers.registerRemoteSources(playerManager,
                                          com.sedmelluq.discord.lavaplayer.source.youtube.YoutubeAudioSourceManager.class);

Otherwise, you will need to register each source manager individually.

In addition, there are a few significant changes to note:

This source's class structure differs so if you had custom classes that you were initialising the source manager with (e.g. an overridden YoutubeTrackDetailsLoader), this is not compatible with this source manager.
