How to implement a video-on-demand workflow on AWS leveraging AWS Step Functions and Elastic Transcoder.

Source code for the AWS solution Video on Demand on AWS.

• cfn/video-on-demand.template

lambda/functions - Micro services that make up the AWS Step Functions.

• dynamo-entry - creates the initial DynamoDB entry for the source video.
• encode-hls - creates an HLS encode job on Elastic Transcoder based on the profiler.
• encode-mp4 - creates an MP4 encode job on Elastic Transcoder based on the profiler.
• ingest-execute - triggers ingest step functions workflow on s3 put object event.
• metadata - creates a json metadata file for the mp4 output.
• preset-check - determines if the ETS complete job is HLS or MP4.
• profiler - determines which ETS profile to use based on the source video height.
• publish-execute - triggers publish step functions workflow on ETS completion.
• publish - publishes workflow results to SNS

lambda/mediainfo

• index - runs mediainfo executable on s3 signed url. https://mediaarea.net/en/MediaInfo

lambda/metrics

• index - Anonymous data

lambda/resources - Custom Resources for CloudFormation to deploy Elastic Transcoder, AWS Step Functions and more.

• cloudfront-identity - creates a CF identity.
• ets-pipeline - creates ETS pipeline.
• ets-presets - creates ETS presents based on Apple tech note from 2016.
• ingest-stepfunctions - creates the ingest state machine.
• publish-stepfunctions - creates the ingest state machine.
• s3-notification - creates s3 events for put objects on the source bucket to trigger ingest-execute.
• sns-subscription - subscribes publish-execute to the ETS Complete SNS topic.
