Introduction to m3u8stream

m3u8stream is a versatile library used for working with HLS (HTTP Live Streaming) streams. It simplifies the process of downloading and parsing M3U8 playlists, making it easier for developers to handle streaming content efficiently.

Setting Up m3u8stream

  
    npm install m3u8stream
  

Downloading a Stream

Below is an example of how to download a stream using m3u8stream:

  
    const m3u8stream = require('m3u8stream');

    const stream = m3u8stream('http://example.com/playlist.m3u8');
    stream.pipe(fs.createWriteStream('output.ts'));
  

Handling Errors

It is important to handle errors properly in your streaming application:

  
    stream.on('error', (err) => {
      console.error('Stream Error: ', err);
    });
  

Monitoring Progress

You can monitor the progress of your stream download:

  
    let downloaded = 0;
    stream.on('data', (chunk) => {
      downloaded += chunk.length;
      console.log('Downloaded: ', downloaded);
    });
  

Using Specific Bandwidth

You can specify the bandwidth you want to use:

  
    const options = {
      id: '1080p',
      bandwidth: 5000000
    };
    const stream = m3u8stream('http://example.com/playlist.m3u8', options);
    stream.pipe(fs.createWriteStream('output.ts'));
  

Custom Headers

If you need to use custom headers for your request, you can do so as follows:

  
    const options = {
      headers: {
        'User-Agent': 'My-User-Agent'
      }
    };
    const stream = m3u8stream('http://example.com/playlist.m3u8', options);
    stream.pipe(fs.createWriteStream('output.ts'));
  

Full Application Example

Here is a full example that combines multiple features:

  
    const fs = require('fs');
    const m3u8stream = require('m3u8stream');

    const options = {
      bandwidth: 3000000,
      headers: {
        'User-Agent': 'My-User-Agent'
      }
    };

    const stream = m3u8stream('http://example.com/playlist.m3u8', options);
    let downloaded = 0;

    stream.on('data', (chunk) => {
      downloaded += chunk.length;
      console.log('Downloaded: ', downloaded);
    });

    stream.on('error', (err) => {
      console.error('Stream Error: ', err);
    });

    stream.pipe(fs.createWriteStream('output.ts')).on('finish', () => {
      console.log('Download completed');
    });
  

By integrating m3u8stream into your application, you can efficiently handle streaming content and provide a seamless experience for your users.
