Video is consumed over the internet in two main modes: on-demand (VOD) or as a real-time (live) stream.
Video-on-demand streaming could be compared to renting or owning a DVD. The viewer may subscribe to a service, or pay a one-time fee, or purchase a movie. For the period of time that access is granted, the viewer can start, stop, pause, rewind, fast forward across the entire duration of the VOD asset.
Live streaming is exactly what it says it is: live. The stream may be a mix of pre-recorded content (e.g., interviews) and live action (e.g., sports), but it has a defined start and stop time. The online viewer can join the stream and perhaps go “back in time” but eventually the stream will end and will no longer be accessible.
Live streaming is growing rapidly. More live streaming content is being made available by studios, as well as by users sharing on social networks. And, there are more devices capable of streaming live video streaming being deployed to the market (for example, smart phones, tablets, PC, smart TV, set-top box, etc.).
In this lab, you will create a live streaming video workflow using AWS Elemental MediaLive, AWS Elemental MediaPackage, and Amazon CloudFront.
Live Streaming Workflow
Live streaming involves three main stages:
Encoding/compression: In this stage a high-resolution, high-bitrate source stream is compressed into several lower-resolution/bitrate versions, suitable for streaming in real time over the internet.
Packaging: The compressed video steams are packaged into segments, usually 2-10 seconds each. This allows video players to adapt to fluctuating network conditions by requesting successive segments from the list of available resolutions/bitrates. This is called adaptive bitrate streaming, or ABR.
Distribution: In order to serve hundreds, thousands, or millions of simultaneous viewers, the packaged video streams need to be fanned out through large distribution networks. This is referred to as the Content Delivery Network or Content Distribution Network (CDN).
In this lab, you will build the live streaming workflow depicted in the image above. You will:
Set up AWS Elemental MediaLive to ingest two source input feeds and transcode the content into two adaptive bitrate (ABR) HTTP Live Streaming (HLS) streams as output (Encoding/compression).
Configure AWS Elemental MediaPackage to ingest the MediaLive output and package the live stream into HLS formats that are delivered to two MediaPackage endpoints (Packaging).
Configure an Amazon CloudFront distribution to use the MediaPackage custom endpoints as its origin, so that the CloudFront distribution can deliver your live stream to viewers for access via mobile devices and desktop browsers with low latency and high transfer speeds (Distribution).
By the end of this lab, you will be able to:
- Connect AWS Elemental MediaLive to an incoming source
- Use MediaLive to create multiple bitrate versions of a source media file
- Configure MediaPackage and CloudFront to deliver live streaming content to mobile and desktop devices
- Play your live video stream on your mobile device or computer
