• Streaming mp3 using node http to Icecast server gives no output

  6 décembre 2024, par Roboroads

  I'm trying to stream a custom mp3 datastream to Icecast2. Icecast recognises there's a mountpoint, however the streamed data won't play and I have no idea why.

  


  import ffmpeg from 'fluent-ffmpeg';
import { request } from 'node:http';

const req = request(
  {
    host: 'localhost',
    port: 8000,
    path: '/radio',
    method: 'PUT',
    auth: 'source:password',
    headers: {
      'Content-Type': 'audio/mpeg',
      Expect: '100-continue',
      'Ice-Public': 0,
      'Ice-Name': 'Testing Stream!',
      'Ice-Description': 'Testing Stream!',
      'Ice-Genre': 'Various',
      'Icy-MetaData': 1
      //'Icy-MetaInt': metaInt
    }
  },
  (res) => {
    console.log('Server responded with status code:', res.statusCode);
    res.on('data', (chunk) => {
      console.log('Response chunk:', chunk.toString());
    });
  }
);

req.on('error', (err) => {
  console.error('Error streaming to Icecast server:', err);
});

req.on('close', () => {
  console.error('Icecast server closed connection');
  process.exit(1);
});

req.on('continue', () => {
  console.log('Continue event received');
  ffmpeg({ source: 'test.mp3' })
    .native()
    .outputOption(['-map 0:a'])
    .audioBitrate(320)
    .audioCodec('libmp3lame')
    .audioFrequency(44100)
    .audioChannels(2)
    .format('mp3')
    .on('progress', (progress) => {
      console.log('Is open:' + req.socket.writable + ' - ' + progress.timemark);
    })
    .on('start', function (commandLine) {
      console.log('Spawned Ffmpeg with command: ' + commandLine);
    })
    .on('end', () => {
      console.log('Processing finished !');
      req.end();
    })
    .on('error', (err) => {
      console.error('FFmpeg error:', err);
    })
    .pipe(req);
});


  


  Note that when I try to do this with ffmpeg using the icecast protocol, it works without issues : ffmpeg -re -i test.mp3 -b:a 320k -acodec libmp3lame -ar 44100 -ac 2 -map 0:a -f mp3 icecast://source:password@localhost:8000/radio. It looks like something is not right with request.

  Error : POST http://localhost:3000/api/video/thumbnail 500 (Internal Server Error)
TypeError : Cannot read properties of undefined (reading 'format')

  


  I think is because ffmpeg is not connecting to mongodb
