srtrelay

Streaming-Relay for the SRT-protocol

Use at your own risk.

Quick start

Run with docker (Note: nightly image not recommended for production)

docker run -p 1337:1337/udp --rm ghcr.io/voc/srtrelay/srtrelay:latest

# start publisher
ffmpeg -i test.mp4 -c copy -f mpegts srt://localhost:1337?streamid=publish/test

# start subscriber
ffplay -fflags nobuffer srt://localhost:1337?streamid=play/test

Start docker with custom config. See config.toml.example

# provide your own config from the local directory
docker run --rm -v $(pwd)/config.toml:/home/srtrelay/config.toml ghcr.io/voc/srtrelay/srtrelay:latest

Run with docker-compose

In your docker-compose.yml:

   srtrelay:
     image: ghcr.io/voc/srtrelay/srtrelay:latest
     restart: always
     container_name: srtrelay
     volumes:
       - ./srtrelay-config.toml:/home/srtrelay/config.toml
     ports:
       - "44560:1337/udp"

This will forward port 44560 to internal port 1337 in the container. Importantly, forwarding UDP is required. It will also copy a srtrelay-config.toml file in the same directory into the container to use as config.toml

Start the server with the usual

docker-compose up -d
