API
YTDL(youtubeURL, options)
Similar to ytdl-core but this method allows you to pass custom FFmpeg args in options.
ytdl("https://youtube.com/watch?v=ERu6jh_1gR0", {
filter: "audioonly",
fmt: "mp3",
encoderArgs: ['-af', 'bass=g=10']
}).pipe(fs.createWritestream("bass_boosted.mp3"));
YTDL.arbitraryStream(source, options)
This method allows you to play the stream from other sources rather than just youtube
. Stream source must be a string or stream object (internal.Readable | internal.Duplex).
Through URL: https://listen.moe/kpop/opus
Using fs:
let stream = fs.createReadStream("./music.mp4");
ytdl.arbitraryStream(stream, {
fmt: "mp3",
encoderArgs: ["bass=g=5"]
}).pipe(fs.createWriteStream("./music.mp3"))
Options
This package provides 4 extra options excluding ytdl-core options.
-
seek
: This option takes the time in seconds.
If this option is provided, it will return the stream from that frame.
Seek option is provided here because discord.js seek doesn't work for ogg/opus
& webm/opus
stream.
This option is ignored when the supplied parameter type isn't a number.
-
encoderArgs
: This option takes the Array of FFmpeg arguments.
Invalid args will throw error and crash the process.
This option is ignored when the supplied parameter type isn't array. Invalid FFmpeg args might crash the process.
-
opusEncoded
: This option takes a Boolean value. If true, it returns opus encoded
stream.
If fmt
option isn't provided, it returns converted
stream type of discord.js. Other values returns unknown
stream if opusEncoded
is false.
-
fmt
: Forcefully changes the stream format. Don't use this option for default value. Even though this option changes the format,
it returns opus
stream if opusEncoded
is set to true
.
-
Other options are the options for ytdl-core.
Example
Playing Opus Encoded Stream
const ytdl = require("discord-ytdl-core");
const Discord = require("discord.js");
const client = new Discord.Client();
client.on("ready", () => {
console.log("ready")
});
client.on("message", msg => {
if (msg.author.bot || !msg.guild) return;
if (msg.content === "!play") {
if (!msg.member.voice.channel) return msg.channel.send("You're not in a voice channel?");
let stream = ytdl("https://youtube.com/watch?v=ERu6jh_1gR0", {
filter: "audioonly",
opusEncoded: true,
encoderArgs: ['-af', 'bass=g=10,dynaudnorm=f=200']
});
msg.member.voice.channel.join()
.then(connection => {
let dispatcher = connection.play(stream, {
type: "opus"
})
.on("finish", () => {
msg.guild.me.voice.channel.leave();
})
});
}
});
client.login("TOKEN");
Unknown Stream

if (msg.content === "!play") {
if (!msg.member.voice.channel) return msg.channel.send("You're not in a voice channel?");
let stream = ytdl("https://youtube.com/watch?v=ERu6jh_1gR0", {
filter: "audioonly",
opusEncoded: false,
fmt: "mp3",
encoderArgs: ['-af', 'bass=g=10,dynaudnorm=f=200']
});
msg.member.voice.channel.join()
.then(connection => {
let dispatcher = connection.play(stream, {
type: "unknown"
})
.on("finish", () => {
msg.guild.me.voice.channel.leave();
})
});
}
});
client.login("TOKEN");
Converted Stream
const ytdl = require("discord-ytdl-core");
const Discord = require("discord.js");
const client = new Discord.Client();
client.on("ready", () => {
console.log("ready")
});
client.on("message", msg => {
if (msg.author.bot || !msg.guild) return;
if (msg.content === "!play") {
if (!msg.member.voice.channel) return msg.channel.send("You're not in a voice channel?");
let stream = ytdl("https://youtube.com/watch?v=ERu6jh_1gR0", {
filter: "audioonly",
opusEncoded: false,
encoderArgs: ['-af', 'bass=g=10,dynaudnorm=f=200']
});
msg.member.voice.channel.join()
.then(connection => {
let dispatcher = connection.play(stream, {
type: "converted"
})
.on("finish", () => {
msg.guild.me.voice.channel.leave();
})
});
}
});
client.login("TOKEN");
Downloading the video
const ytdl = require("../index.js");
const { createWriteStream } = require ("fs");
const url = "https://www.youtube.com/watch?v=zrwTYozyzYA";
let stream = ytdl(url, {
encoderArgs: ["-af", "asetrate=44100*1.25,bass=g=20,dynaudnorm=f=150"],
fmt: "mp3",
opusEncoded: false
});
stream.pipe(createWriteStream(__dirname+"/test.mp3"));
Arbitrary Stream
const ytdl = require("discord-ytdl-core");
const Discord = require("discord.js");
const client = new Discord.Client();
client.on("ready", () => {
console.log("ready")
});
client.on("message", msg => {
if (msg.author.bot || !msg.guild) return;
if (msg.content === "!play") {
if (!msg.member.voice.channel) return msg.channel.send("You're not in a voice channel?");
let stream = ytdl.arbitraryStream("https://listen.moe/kpop/opus", {
