How to implement a video-on-demand workflow on AWS leveraging AWS Step Functions and AWS Elemental MediaConvert.
Source code for the AWS solution Video on Demand on AWS.
There are 2 CloudFormation templates, one to deploy the workflow with AWS Elemental MediaConvert and a second which deploys ElasticTranscoder.
source/custom-resources: A series of CloudFormation custom resources used to deploy Elastic Transcoder, MediaConvert custom presets and make configuration changes to S3 SNS and CloudFront.
source/dynamo A Lambda function to update DynamoDB, used in each of the Step Functions workflows.
source/error-handler A Lambda function to handle workflow and ElasticTranscoder errors
source/ingest The Lambda functions that make up the core of the ingest workflow.
source/mediainfo A Lambda function to run mediainfo on s3 signed url. https://mediaarea.net/en/MediaInfo. bin/mediainfo must be made executable before deploying to lambda.
source/process The Lambda functions that make up the core of the process workflow.
source/publish The Lambda functions that make up the core of the publish workflow.
source/sns a lambda function used to send publish and/or error notifications
We recommend building this package on Amazon Linux because the target Lambda environment will run on Amazon Linux and the build process compiles MediaInfo
# Install Development Tools necessary to compile MediaInfo
sudo yum groupinstall 'Development Tools' -y
# Install library required to add CURL support to Mediainfo
sudo yum install libcurl-devel -y
cd deployment
./build-s3-dist.sh source-bucket-base-namesource-bucket-base-name should be the base name for the S3 bucket location where the template will source the Lambda code from. The template will append '-[region_name]' to this value. For example: ./build-s3-dist.sh solutions The template will then expect the source code to be located in the solutions-[region_name] bucket
