Source monitoring for AWS Elemental MediaLive via Amazon Rekognition

This article discusses a solution for source monitoring for AWS Elemental MediaLive using Amazon Rekognition. It allows detecting impaired video input sources, like black video, color bars, or frozen frames, which would otherwise go undetected.

Specifically, the article covers:

• Leveraging MediaLive's input source thumbnails and passing them to Amazon Rekognition for image properties analysis
• Using Rekognition's response data (brightness, sharpness, contrast) to detect anomalies like black frames or frozen input
• A basic solution using AWS Lambda triggered by CloudWatch Scheduler to poll thumbnails periodically
• An advanced solution using AWS Fargate for lower latency detection, handling multiple channels more effectively
• Configuring CloudWatch alarms based on the detected anomalies to alert operators or take automated actions
