Creating a Live-to-VOD workflow using AWS Elemental Services and the AWS serverless platform

This repository contains the full source code that is used in the blog post Create a serverless Live-to-VOD workflow with AWS Elemental.

Solution Overview

Prerequisites

• An AWS account
• Installed and authenticated AWS CLI (authenticate with an IAM user or an AWS STS Security Token)
• AWS Serverless Application Model (AWS SAM)
• You have completed steps 1-3 of the AWS Live Streaming and Live-to-VOD Workshop or already have an AWS Elemental MediaPackage live endpoint you want to extract clips from. You can check your existing endpoints using the following CLI command.

aws mediapackage list-origin-endpoints

Let’s get you started

1. Make sure you completed the prerequisites above and git pulled this repo.

git clone [email protected]:aws-samples/live-to-vod-workflow-using-aws-serverless-platform

2. Open the repository in your preferred IDE and familiarize yourself with the code.

• sam.yml describes the AWS resources that make up your workflow.
• handler.py contains the Python code for our Lambda functions.
• create_packaging_group.py is a convenience script to create a packaging group.

3. Create a deployment bucket for our code on S3.

aws s3 mb s3://<YOUR_BUCKET>

4. Create a packing group and note the PACKAGING_GROUP_ID

python create_packaging_group.py <THE_ID_FOR_YOUR_PACKAGING_GROUP> <THE_ID_FOR_YOUR_PACKAGING_CONFIG>

i.e.

python create_packaging_group.py MyPackagingGroupForVOD MyPackagingConfigForVODInHLS

5. Create a SAM package of your application for deployment

sam package --template-file ./sam.yml --s3-bucket <YOUR_BUCKET>  --output-template-file ./packaged.yml

6. Deploy your application

sam deploy --template-file packaged.yml --stack-name ServerlessLiveToVOD --capabilities CAPABILITY_NAMED_IAM --parameter-overrides ClipsOriginEndpointId=YOUR_ORIGIN_ID PackagingGroupId=YOUR_PACKAGING_GROUP_ID

If you are unsure about the values for ClipsOriginEndpointId and PackagingGroupId you can check the AWS console or use the following CLI commands

List Origin Enpoints

aws mediapackage list-origin-endpoints --query "OriginEndpoints[*].[Id]" --output table

List Packaging Groups

aws mediapackage-vod list-packaging-groups --query "PackagingGroups[*].Id" --output table

After the deployment has been successful, SAM will output a parameter API endpoint URL. The value should look similar to this: https://abcde.execute-api.eu-central-1.amazonaws.com/prod/ - this is your API endpoint, which you can now use to create clips from your live stream and query your clip database.

Cleaning up

When you are done, make sure to clean everything up. Run the following command to shut down the resources created in this workshop.

aws cloudformation delete-stack --stack ServerlessLiveToVOD

If you used the AWS Live Streaming and Live-to-VOD Workshop please follow the instructions to clean up the AWS Elemental resources if no longer needed.
