Simple Low Latency Streaming Platform

Features

• Sub-second end-to-end latency via WebRTC
• Configurable latency (down to 1 second) via LL-DASH
• Royalty free solution - based on open-source OvenMediaEngine
• RTMP ingest - broadcast with any capable software (i.e. OBS) or hardware (i.e. LiveU)
• WebRTC egress - plays in any WebRTC capable browser
• MPEG-DASH (Chunked CMAF) egress - plays in a variety of browsers

Setup

Deploying the architecture

1. Sign in to the AWS Management Console
2. Switch to the AWS region that is closest to your broadcast location
3. Click the button below to launch the CloudFormation template. Alternatively you can download the template and adjust it to your needs.

4. Choose the instance type for your server; make your choice depending on how much you will need to stream (use figures here as reference); you will be able to change the instance size later, or just discard the stack and create a new one with a different setup
5. Leave all other settings to default
6. Hit the Create Stack button.
7. Wait for the Status to become CREATE_COMPLETE. Note that this may take 1-2 minutes or more.
8. Under Outputs, notice the keys named IngressEndpoint, LLHLSDemoPlayerUrl and WebRTCDemoPlayerUrl; write these down for using later

Testing your setup

1. Point your RTMP broadcaster (any of these will work) to the RTMP IngressEndpoint output by CloudFormation above

   Note that, while some RTMP broadcasters require a simple URI, others (like OBS Studio) require a Server and Stream key. In this case, split the URI above at the last slash character, as following:

   Server: rtmp://[HOST]/app
   Stream key: stream001

   Also note that the enpoint may not be ready as soon as CloudFormation stack is complete; it may take a couple minutes more for the server software to be compiled, installed and started on the virtual server so be patient

2. Open the LL-HLS test player URL output by CloudFormation above as LLHLSDemoPlayerUrl to view the LL-HLS stream; you may experiment with different delay settings (2 seconds by default) by adjusting the LL-DASH Live Delay value

3. Open the WebRTC test player URL output by CloudFormation above as WebRTCDemoPlayerUrl to view the WebRTC stream

Integration

For WebRTC playback, you'll have to set up and integrate the free OvenPlayer here. The same OvenPlayer can be used for LL-DASH, or any other compatible player.

Notes

• POC only uses a single stream, namely stream1; you can freely use another name, also run multiple streams simultaneously
• The CloudFormation template creates a VPC with the internal IP range 10.132.0.0/16; be sure to change this if it overlaps with other VPCs
