• 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",
  
      "jpg": "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);

  The test.m3u8 looks like this

  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.

• FFmpeg file not found exception

  26 mai 2018, par Sagar Hudge

  I am getting following exception on video trimming.

  video path : /storage/emulated/0/Pictures/Instagram/Fast & Furious 7 - Get Low Extended Version Video.mp4

  file name : Fast & Furious 7 - Get Low Extended Version Video.mp4

  and ffmpeg searching for only Fast in

  /storage/emulated/0/Pictures/Instagram/Fast: No such file or directory

  I have found the issue ,it is causing due to the file name having spaces in between them you can check in above mentioned path and in exception.

  after changing file name its working but changing name of every file from device its not the right way so how can I solve this exception
