Here is one way you could design a low latency live streaming service using open source tools:
- Choose a streaming server: One option could be using the open source Nimble Streamer server, which supports a variety of streaming protocols, including WebRTC, RTMP, and HLS. It can be run on Linux, Windows, or macOS, and it has a built-in load balancer and transcoder to help you scale the service and support multiple bitrates and resolutions.
- Configure the server: Once you have installed the Nimble Streamer server, you will need to configure it to receive the live stream from the broadcaster. This can be done using a variety of methods, such as RTMP or WebRTC publishing. You can also set up authentication and access controls to ensure that only authorized broadcasters can stream to the server.
- Set up a signaling server: In order to establish a WebRTC connection, you will need a signaling server to exchange metadata between the broadcaster and viewer. One option could be using the open source Janus Gateway server, which is a general-purpose WebRTC server that can handle a variety of use cases, including videoconferencing, streaming, and interactive voice and video.
- Integrate with a player: To play the live stream on the viewer’s end, you will need a player that is compatible with the streaming protocol you are using. For example, if you are using HLS, you can use the HTML5 video player or a third-party player like VLC or QuickTime. If you are using WebRTC, you can use a player that supports WebRTC, such as the WebRTC-based player provided by the Nimble Streamer server.
- Monitor and scale the service: To ensure that the service is running smoothly, you can use tools like the Nimble Streamer dashboard or server logs to monitor the performance and identify any issues. You can also use the built-in load balancer and transcoder to scale the service as needed to handle more viewers or higher traffic.
There is no one best solution for a low latency Live Stream service
Overall, this is just one possible approach to setting up a low latency live streaming service using open source tools. There are many other options available, and the specific solution that is right for you will depend on your specific requirements and constraints.
