A high-performance video processing pipeline built in Go.
The service consumes background jobs from Redis, downloads uploaded videos, transcodes them into multiple HLS renditions, generates thumbnails and master playlists, uploads processed assets to Amazon S3, and notifies the API when processing is complete.
