Serverless Video Streaming Solution

The platform consists of the following modules:

Media Proxy: The high available proxy server cluster is built on Amazon ECS Service.

• provide RTMP streaming addresses
• support the access of large number of devices
• leverage lightweight HAProxy to provide unified streaming addresses

Media Gateway: Based on Node-Media-Server, the high-performance and light-weight RTMP server does the following:

• provide accesses for RTMP/RTMPs streams
• maintain metadata of video streams such as streaming status, channel session etc.
• maintain streaming client status based on events
• monitor client status and schedule ECS tasks accordingly

Metadata Management: This module mainly leverages Amazon DynamoDB to manage the metadata of video streams. The module does the following:

• provide RESTful APIs for CRUD management through Amazon API Gateway
• dynamically configure video stream processing parameters
• automatically generate a unique video push channel
• fetch URLs of video pushing and pulling through APIs

Media Processor: The module leverages Amazon ECR Fargate to provide features such as video live streaming, video transcoding, video recording, video segmentation, etc. The module does the following:

• encode and transcode video in real-time
• segment videos and images and store the segments in Amazon S3
• allow customization of segment time and transcoding parameters
• support HTTP-FLV (~2 seconds delay) and HLS/CMAF (~10 seconds delay)

Media Distribution: The module leverages Amazon ECS Fargate and Amazon CloudFront to provide seamless video experience. The module does the following:

• compose multiple input streams to single output stream
• leverage built-in nginx cache to avoid thundering herd problem
• secure access with signed URLs

Web Console: Note that the console is for demonstration purposes only. By default, solution will NOT create the web console. You need to explicitly configure it in the CloudFormation parameter before deployment.
