• Node.js Stream Mp3 to http without having to save file

  10 janvier 2019, par user2758113

  I am trying to stream just audio from a youtube link straight to http with node.js.

  My code looks like this, I am using express 4.0.

  var express = require('express');
  
  var router = express.Router();
  
  var ytdl = require('ytdl');
  
  var ffmpeg = require('fluent-ffmpeg');
  
  var fs = require('fs');
  
  
  
  router.get('/', function(req, res) {
  
  
  
    var url = 'https://www.youtube.com/watch?v=GgcHlZsOgQo';
  
    var video = ytdl(url)
  
  
  
    res.set({
  
        "Content-Type": "audio/mpeg"
  
    })
  
  
  
    new ffmpeg({source: video})
  
        .toFormat('mp3')
  
        .writeToStream(res, function(data, err) {
  
          if (err) console.log(err)
  
        })
  
  
  
  });
  
  
  
  module.exports = router;

  Now, I’m able to stream the video’s audio to the response if I save the file then pipe it to the response, but I’d rather try to figure out some way to go from downloading to ffmpeg to response.

  Not sure if this is possible. The main goal is to keep it as light weight as possible, and not have to read from files.

  I’ve seen this code which is essentially what I’d like to do minus the saving to a file part.

  

• ffmpeg - How to pass http headers ?

  30 novembre 2015, par Lizozom

  I need to pass http headers (user agent and ip) to an ffmpeg command.

  I use the following command :

  ffmpeg  -y -timeout 5000000 -map 0:0 -an -sn -f md5 - -headers "User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.36" -headers "X-Forwarded-For: 13.14.15.66"  -i "http://127.0.0.1" 

  And I run a local node.js server to see the headers I get :

  'use strict';
  
  
  
  var express = require('express');
  
  
  
  var server = express();
  
  
  
  server.all('/*', function(req, res) {
  
    console.log(JSON.stringify(req.headers));
  
    res.sendFile('SampleVideo_1080x720_1mb.mp4', {root: '.'});
  
  
  
  });
  
  
  
  
  
  server.listen(80);

  I keep getting an error saying "No trailing CRLF found in HTTP header." and the request is stuck.

  If I drop the headers - everything works normally.

  I also tried putting both headers in one string, but any line breaking character I used (\r\n, \r\n, etc.) didn’t work.

  Can someone help me figure out how to write this command correctly with the headers included ?
