Docker Container for SRS Low Latency Build

Docker container for a low latency build of SRS. Intended for deployment for XTV for outside broadcast on the UK General Election 2017.

Building

The docker container can be built with docker-compose and the following command:

docker-compose build

Running

The container can be run in detached mode using the following command:

docker-compose up -d

The logs can be viewed using:

docker-compose logs

Usage

The container exposes port 1935 (the RMTP port). Streams can be created using an RTMP streaming encoder such as OBS, FMLE or Teradek Live:Air Solo. The stream should have the following settings:

rtmp://<address>/live/<stream_key>

Where <address> is the server IP or domain name and <stream_key> is the stream key for the encoder. For example:

rtmp://live.xtv.co.uk/live/corn_exchange

This stream can then be accessed using VLC media player by opening a network stream with the following settings:

rtmp://<address>/live/<stream_key> :network-caching=0

Here the the final part of the address disables VLC caching the incoming stream, minimising latency. Using the previous example:

rtmp://live.xtv.co.uk/live/corn_exchange :network-caching=0
