Video streaming with HTML 5 via node.js

Question

I\'m trying to set up a web server that will support streaming video to an HTML5 video tag using node.js. Here\'s my code so far:

var range = request.header         


        

Answer 1

I am using the MVC framework sails.js on top of Node.js and I managed to get it working fine with the following code:

/**
 * VideoController
 *
 * @module      :: Controller
 * @description :: Contains logic for handling requests.
 */

 var fs = require('fs');

module.exports = {

  /* e.g.
  sayHello: function (req, res) {
    res.send('hello world!');
  }
  */

  /**
   * /video/stream
   */ 
  stream: function (req,res) {

    // This will render the view: 
    // C:\Users\sam\Documents\Dev\Fun\mymoviebank/views/video/stream.ejs
    res.view();

  },

  play: function (req,res) {

    fs.readFile('/Users/sam/Videos/big_buck_bunny.mp4', function (err, data) {
      if (err) throw err;

      var range = req.headers.range;
        var total = data.length;

        var parts = range.replace(/bytes=/, "").split("-");
        var partialstart = parts[0];
        var partialend = parts[1];

        var start = parseInt(partialstart, 10);
        var end = partialend ? parseInt(partialend, 10) : total-1;

        var chunksize = (end-start)+1;

        res.writeHead(206, { "Content-Range": "bytes " + start + "-" + end + "/" + total, "Accept-Ranges": "bytes", "Content-Length": chunksize, "Content-Type": 'video/mp4' });
        res.end(data);

    });

  }

};

Hope this helps
