youtube audio stream

youtube-audio-stream

This module streams youtube using ytdl to get the youtube download stream.

To convert to audio the module fluent-ffmpeg is used.

You will need to have ffmpeg and the necessary encoding libraries installed, as well as in your PATH. If you're on OSX, this can be handled easily using Homebrew (brew install ffmpeg).

Getting Started

1. With npm, run npm install youtube-audio-stream
2. var youtubeStream = require('youtube-audio-stream')

Usage

Here is an example that:

1. queries for a video by video ID
2. Retrieves the audio via this package
3. pipes it to res

var getAudio = function (req, res) {
  var requestUrl = 'http://youtube.com/watch?v=' + req.params.videoId
  try {
    youtubeStream(requestUrl).pipe(res)
  } catch (exception) {
    res.status(500).send(exception)
  }
}

Node example playing directly to speaker

const stream = require('youtube-audio-stream')
const url = 'http://youtube.com/watch?v=34aQNMvGEZQ'
const decoder = require('lame').Decoder
const speaker = require('speaker')

stream(url)
.pipe(decoder())
.pipe(speaker())

Testing

This package comes with a simple example for testing. This can be run with the command npm test, which will then serve the example at localhost:3000. The example consists of an <audio> component whose source is retrieved via this package.

Testing inside a docker container
