Architecture

Prerequisites

Before you begin, ensure you have met the following requirements:

• AWS account with necessary permissions
• Docker installed locally for building ECS containers
• Node.js and npm for Lambda function development

Getting Started

To get started with this project, follow these steps:

1. Clone this repository to your local machine.
2. Configure AWS CLI with your credentials and default region.
3. Create S3 buckets for raw and transcoded videos (e.g., RawBucket and TranscodedBucket).
4. Build and deploy the Lambda function in the ./lambda directory.
5. Build and deploy the ECS task using the Dockerfile and task definition in the ./ecs directory.
6. Configure event triggers for the Lambda function to monitor the RawBucket.

How it works

1. Upload a video file to S3 bucket (e.g. RawBucket)
2. S3 event triggers Lambda function (e.g. TranscoderLambda)
3. Lambda function starts ECS task (e.g. TranscoderTask) with the video bucket and key as environment variable
4. ECS downloads the video from S3 bucket (e.g. RawBucket) and transcodes it with ffmpeg to different resolutions (e.g. 1080p, 720p, 480p)
5. ECS uploads the transcoded videos to different S3 bucket (e.g. TranscodedBucket)

Folder structure

• ./lambda: Lambda function source code
• ./ecs: ECS task definition and Dockerfile
