Live streaming on AWS with Amazon S3 automatically configures AWS Elemental MediaLive, Amazon S3 and Amazon CloudFront to ingest, encode, package and deliver a single source live stream through the AWS Cloud. The Solution provides 3 Encoding profiles to support 1080p through 288p HTTP live streaming (HLS) outputs. For more details see thesolution home page.

The solution was developed using theAWS Cloud Development Kit and also leverages a AWS Solutions ConstructCloudFrontToS3

The solution supports RTP Push, RTMP push, HLS andAWS Elemental Link input types. For more detialed instructions see the implementation guide on thesolution home page.

• HD-1080p profile: 1920x1080, 1280x720, 960x540, 768x432, 640x360, 512x288
• HD-720p profile: 1280x720, 960x540, 768x432, 640x360, 512x288
• SD-540p profile: 960x540, 768x432, 640x360, 512x288

The solution can be deployed through the CloudFormation template available on thesolution home page.

• AWS Command Line Interface
• Node.js 12.x or later
• AWS CDK 1.102.0

The are 2 options for deploying the solution: using the CDK deployment tools or running the build script to generate a CFN template and the packaged lambda code.

This options simply flollows the standard CDK deployment process. You will need to runcdk bootstrap before you run cdk deply the first time to setup the cdk resource in your AWS account. Details on using the CDK can be found [here].

1. Download or clone the repo and make the required changes to the source code.
2. installl the dependecies for the lambda function and construct.
3. then runcdk deploy (first time use you will need to runcdk bootstrap first)

cd ./source/custom-resourcenpm install --productioncd ../constructsnpm install cdk bootstrap //if you havent already done so.cdk deploy

The CloudFormation template (generated by the CDK) includes a lambda backed custom resource to configure MediaLive and create a UUID. To launch the solution the Lambda source code has to be deployed to an Amazon S3 bucket in the region you intend to deploy the solution.

Download or clone the repo and make the required changes to the source code.

Run unit tests to make sure added customization passes the tests:

cd ./deploymentchmod +x ./run-unit-tests.sh && ./run-unit-tests.sh

The CloudFormation template is configured to pull the Lambda deployment packages from Amazon S3 bucket in the region the template is being launched in. Create a bucket in the desired region with the region name appended to the name of the bucket. eg: for us-east-1 create a bucket named:my-bucket-us-east-1

aws s3 mb s3://my-bucket-us-east-1

Build the distributable:

chmod +x ./build-s3-dist.sh./build-s3-dist.sh <my-bucket> live-streaming-on-aws-with-amazon-s3 <version>

Notes: Thebuild-s3-dist script expects the bucket name as one of its parameters. This value should not have the region suffix (remove the -us-east-1)

Ensure that you are owner of the AWS S3 bucket.

aws s3api head-bucket --bucket my-bucket-us-east-1 --expected-bucket-owner YOUR-AWS-ACCOUNT-NUMBER

Deploy the distributable to the Amazon S3 bucket in your account:

aws s3 sync ./regional-s3-assets/ s3://my-bucket-us-east-1/live-streaming-on-aws-with-amazon-s3/<version>/ aws s3 sync ./global-s3-assets/ s3://my-bucket-us-east-1/live-streaming-on-aws-with-amazon-s3/<version>/

• Get the link of the live-streaming-on-aws-with-amazon-s3.template uploaded to your Amazon S3 bucket.
• Deploy the solution.

When deploying this solution you may have a DevOps operator IAM user that deploys this CloudFormation template. The json file located at the following directory is the minimum IAM permissions that an AWS IAM user needs to be able to deploy the CloudFormation template successfully.
