• How to download m3u8 to mkv in nodejs

  10 février 2019, par Gabgab2003

  Im trying to download an mkv file from an m3u8 stream. I have the m3u8 as url, but can download it to a file if need be. I would like to solve this only with node and node modules.

  I have already tried to use wget lib, but cant get ffmpeg (node library, not the standalone binary) to work with the file.

  if anyone is interested, the url im trying to download is this
  (Im writing a crunchyroll downloader application)

• Is there a way to stream download a mp3 file that is being converted on a nodejs server ?

  19 février 2019, par Thriskel

  I am looking for a way to send the url to the nodejs server and respond the user with the mp3 file download.

  I searched some examples, and read about requests and responses, but I am not sure what the problem really is.

  This is the Javascript for the HTML :

      var downloadBtn = document.querySelector('.download_button');
  
      var URLinput = document.querySelector('#myUrl');
  
  
  
      downloadBtn.addEventListener('click', () => {
  
          console.log(`URL: ${URLinput.value}`);
  
          sendURL(URLinput.value);
  
      });
  
  
  
      function sendURL(URL) {
  
          window.location.href = `http://localhost:4000/download?URL=${URL}`;
  
      }

  This is the Javascript for the Nodejs server :

  const express = require('express');
  
  const cors = require('cors');
  
  const ytdl = require('ytdl-core');
  
  const app = express();
  
  const ffmpeg = require('fluent-ffmpeg')
  
  app.use(cors());
  
  
  
  app.listen(4000, () => {
  
      console.log('Server Works !!! At port 4000');
  
  });
  
  
  
  app.get('/download', (req,res) => {
  
  var URL = req.query.URL;
  
  
  
  res.header('Content-Disposition', 'attachment; filename="file.mp3"');
  
  let stream = ytdl(URL, { 
  
    quality: 'highestaudio',
  
  }); //HERE THE STREAM FILE IS SELECTED TO BE CONVERTED TO MP3
  
  
  
  ffmpeg(stream)
  
    .audioBitrate(128)
  
    .pipe(res); // HERE IS CONVERTED AND WHERE I WANT IT TO SEND IT AS A DOWNLOAD TO THE USER.
  
  });

  I expected it to stream download the file but instead it gets me to the nodejs server page to /download/url_to_vid
