Module 3: AWS Elemental MediaLive

In this module you'll be creating an AWS Elemental MediaLive input which will in turn get used to set up a AWS Elemental MediaLive channel. During the channel creation, you will need the AWS Elemental MediaPackage endpoints and credentials you have created and saved from the previous module.

Prerequisites

Previous Modules

This module relies on the configuration of AWS IAM and AWS Elemental MediaPackage. You must successfully complete these previous modules before attempting this one.

Implementation Instructions

1. Create an AWS Elemental MediaLive Input

Before you can create a AWS Elemental MediaLive channel, you must first create an input that the channel can attach to.

Step-by-step instructions

  1. From the AWS Management Console, choose Services then select AWS Elemental MediaLive or use the following link.

  2. On the left navigation pane, click on Inputs.

  3. Then click on Create Input.

  4. Enter HLS Input for the Input Name.

  5. Select HLS for Input Type.

  6. Under Input Sources, use http://d2qohgpffhaffh.cloudfront.net/HLS/vanlife/withad/sdr_uncage_vanlife_admarker_60sec.m3u8 for Source A's Source URL of the stream.

  7. Enter the same URL for Source B.

  8. Click Create.

2. Create an AWS Elemental MediaLive Channel

You will now create an AWS Elemental MediaLive Channel that will publish to the MediaPackage endpoints you created in a previous module. The channel will use the input you created in the previous step.

Step-by-step instructions

  1. Still on the AWS Elemental MediaLive console, on the left navigation pane, click on Channels.

  2. Click on Create channel.

  3. Under General Info, enter HLS Stream Channel for Channel Name.

  4. Copy and paste the Role ARN you saved off while working on the IAM module into the IAM role ARN.

  5. Click on Attach Input and select the input (HLS Input) you created from the Input dropdown.

  6. Scroll down to Input Settings. Set Source End Behavior to Loop.

  7. On the left navigation pane, under Output Groups click on Add.

Completion

Congratulations! You have successfully created inputs and channels for AWS Elemental MediaLive to encode video and send to an origin packaging service like AWS Elemental MediaPackage. Move forward to the next module called Browser Page where you will customize an HTML page with a streaming player for one of your AWS Elemental MediaPackage endpoints.

Return to the main page.

Cloud Resource Clean Up

To manually remove resources created in this module, go to the AWS Elemental MediaLive console and stop the channel. Once the channel is Idle delete the channel first, and then delete the input source. AWS Elemental MediaLive will not allow you to remove a channel that is running, nor will it allow you to remove an input that is attached to a channel.
