const WebSocket = require('ws')
const url = require('url')
...

var streamVideo = function (ws, path, query) {
  var paused = false
  var options = {}
  if (query.start !== undefined) {
    options.start = query.start * 1
  }
  if (query.end * 1) {
    options.end = query.end * 1
  }

  ///

  ws.on('close', function () {
    stream.destroy()
  })
  stream.on('data', function (chunk) {
    if (ws.readyState === WebSocket.OPEN) {
      ws.send(chunk)
    }
    stream.pause()
    // WE WANT TO SEND NOT TOO FAST
    setTimeout(function () {
      if (!paused) {
        stream.resume()
      }
    }, 100)
  })
  ws.on('message', function (data) {
    if (data === 'wait') {
