Lab Overview

In this lab, you will use Amazon CloudFront to deliver a dynamic (multiple bit-rate) stream to a connected device using Apple’s HLS (HTTP Live Streaming) protocol. The stream can also be played on any browser that supports the HLS protocol. In this lab, you will also use Amazon Elastic Transcoder to convert a source video into multiple bit-rates that will be delivered using CloudFront.

Topics Covered

This lab covers:

  • Creating multiple bit-rate versions of a given source media file using Amazon Elastic Transcoder.
  • Delivering the dynamic (multi bit-rate) stream created by Amazon Elastic Transcoder, using Amazon CloudFront.

Technical Knowledge Prerequisites

To successfully complete this lab, you should be familiar with the basics of media encoding and have knowledge of core AWS services.

Other AWS Services

Other AWS Services than the ones needed for this lab are disabled by IAM policy during your access time in this lab. In addition, the capabilities of the services used in this lab are limited to what’s required by the lab and in some cases are even further limited as an intentional aspect of the lab design. Expect errors when accessing other services or performing actions beyond those provided in this lab guide.

What is HLS?

Apple Inc. created the HLS protocol. HTTP Live Streaming can dynamically adjust movie playback quality to match the available speed of wired or wireless networks using an ordinary web server. It works by creating different quality streams. Each stream is then broken into chunks that are streamed sequentially to a client device. On the clients end, one can select streams of varying bit rates. This allows streaming sessions to adapt to different network speeds.
