• HLS Streaming using node JS

  20 février 2014, par Tirtha

  I'm trying to stream HLS content using node.js. And somehow it is not working. It'll be of great help if someone helps me out.

  Problem :-
  Trying to serve HLS content from node.js (not live stream, but a set of .ts files and .m3u8 playlist, or in other words VOD content)

  Folder Structure

  stream_test
  
  |--- app.js
  
  |--- node_modules
  
  |--- streamcontent
  
          |--- test.m3u8
  
          |--- segment0.ts
  
          |--- segment1.ts
  
          .
  
          .
  
          .
  
          |--- segment127.ts

  My app.js looks like this

  var http = require('http'),
  
      url = require('url'),
  
      path = require('path'),
  
      fs = require('fs');
  
  var mimeTypes = {
  
      "html": "text/html",
  
      "jpeg": "image/jpeg",

      "png": "image/png",
  
      "js": "text/javascript",
  
      "css": "text/css",
  
      "ts": "video/MP2T",
  
      "m3u8": "application/vnd.apple.mpegurl"};
  
  
  
  http.createServer(function(req, res) {
  
      var uri = url.parse(req.url).pathname;
  
      var filename = path.join(process.cwd(), unescape(uri));
  
      var stats;
  
  
  
      console.log('filename '+filename);
  
  
  
      try {
  
          stats = fs.lstatSync(filename); // throws if path doesn't exist
  
      } catch (e) {
  
          res.writeHead(404, {'Content-Type': 'text/plain'});
  
          res.write('404 Not Found\n');
  
          res.end();
  
          return;
  
      }
  
  
  
  
  
      if (stats.isFile()) {
  
          // path exists, is a file
  
          var mimeType = mimeTypes[path.extname(filename).split(".")[1]];
  
          res.writeHead(200, {'Content-Type': mimeType} );
  
  
  
          var fileStream = fs.createReadStream(filename);
  
          fileStream.pipe(res);
  
      } else if (stats.isDirectory()) {
  
          // path exists, is a directory
  
          res.writeHead(200, {'Content-Type': 'text/plain'});
  
          res.write('Index of '+uri+'\n');
  
          res.write('TODO, show index?\n');
  
          res.end();
  
      } else {
  
          // Symbolic link, other?
  
          // TODO: follow symlinks?  security?
  
          res.writeHead(500, {'Content-Type': 'text/plain'});
  
          res.write('500 Internal server error\n');
  
          res.end();
  
      }
  
  
  
  }).listen(8000);

  I used ffmpeg to create the segments and palylist

  ffmpeg -i video-a.mp4  -c:a libmp3lame -ar 48000 -ab 64k  -c:v libx264   -b:v 128k -flags -global_header -map 0 -f segment  -segment_list test.m3u8 -segment_time 30 -segment_format mpegts segment_%05d.ts

  Test Scenraio :-
  Works fine if served from Apache, does not if served from node.

  Test Tool :-
