// Let's say you have a function that does some async operation inside setTimeout (think of polling for data)

function runInterval(callback, interval = 1000) {
  setInterval(async () => {
    const results = await Promise.resolve(42) // this might fetch some data from server
    callback(results)
  }, interval)

Adaptive Streaming has become the neccessity for streaming video and audio. Unfortantely, as of this post, there isn't a whole lot of tutorials that accumulate all of the steps to get this working. Hopefully this post achieves that. This post focuses on using Amazon Web Services (AWS) to transcode for HLS and DASH and be the Content Delivery Network (CDN) that delivers the stream to your web page. We'll be using Video.js for the HTML5 player as well as javascript support libaries to make Video.js work with HLS and DASH.

So Here's what you need:

• An AWS Account
• Video.js
• videojs-contrib-hls.min.js
• dash.all.min.js
• videojs-dash.min.js

  function construct(constructor, args) {
    var c : any = function () {
      return constructor.apply(this, args);
