Question

我想使用nodejs来创建一个流媒体服务器（我知道有很多，但我想用nodejs创建一个），问题是视频没有像在youtube上那样下载，你能不能给出如何要像youtube一样获得流式传输，谢谢

var http = require('http'),
var fs = require('fs'),
var util = require('util');

http.createServer(function (req, res) {
var path = '/home/flumotion/test.mp4';
var stat = fs.statSync(path);
var total = stat.size;
if (req.headers['range']) {
    var range = req.headers.range; 
    console.log("Range = "+range);
    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;
    console.log('RANGE: ' + start + ' - ' + end + ' = ' + chunksize);

    var file = fs.createReadStream(path, {start: start, end: end});
    res.writeHead(206, { 'Content-Range': 'bytes ' + start + '-' + end + '/' + total, 'Accept-Ranges': 'bytes', 'Content-Length': chunksize, 'Content-Type': 'video/mp4' });
    file.pipe(res);
  } 
  else {
    console.log('ALL: ' + total);
    res.writeHead(200, { 'Content-Length': total, 'Content-Type': 'video/mp4' });
    fs.createReadStream(path).pipe(res);
  }
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');
