How to concatenate multiple Start Stop chunks of recordings using ChimeSDK Concatenation API

In order to create media concatenation pipeline we use Media capture pipelines capture the contents of a meeting by chunking the media streams and storing those artifacts in your S3 bucket and Media concatenation pipelines allow you to concatenate each type of artifact into a single file, and then store those larger files in your S3 bucket. You can create a media concatenation pipeline without waiting for the media capture event to end, but the concatenation pipeline only starts concatenating when the capture pipeline stops.

Please refer the architecture of the Concatenation pipeline: https://docs.aws.amazon.com/chime-sdk/latest/dg/concat-architecture.html

Please refer the documentation to create an Amazon Chime SDK media concatenation pipeline: https://docs.aws.amazon.com/chime-sdk/latest/dg/create-concat-pipe-steps.html

The Amazon S3 buckets for media concatenation pipelines use this folder structure.

S3 bucket path/
  audio
  video
  data-channel
  meeting-events
  transcription-messages
