• Save http stream video android

  11 novembre 2013, par ChebTS

  For one of my android projects I need to implement saving of video from HTTP stream (right now I am just show live stream video to user).

  I google that problem and find some solution, I can use FFmpeg. But FFmpeg is c++ library.

  Is there are some easy way to save video from HTTP stream ?

• 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.
