# Overview

This project allows upload of HLS based streaming data from the SRS (Simple Realtime Server, https://ossrs.io/) to an S3 based storage. The purpose is to publish a stream in HLS format to a cloud based data store to leverage CDN distribution.

This project implements a NodeJs based webserver that provides a web hook that can be registered with SRS's `on_hls` webhook. Whenever a new video segment is created, this web hook is called and the implementation in this project uploads the `.ts` video segment as well as the `.m3u8` playlist information 
to the storage bucket.

To keep the bucket usage limited to a small amount of data, segments before a certain time frame (e.g. 60s) are automatically deleted from the bucket.

# Configuration

Create a `.env` file based on `.env.sample` with the S3 credentials

rtmp://localhost/live

any stream key

# Usage

```
docker build -t srs-s3 .
docker run -p 1935:1935 -it --rm srs-s3
```



# Known Limitation

* Currently only streams with 1 camera and 1 format are supported.
* This upload/sync job needs to run on the same machine as SRS, since data is read from the local hard disk. This is the reason it currently runs in the same docker container.
