SRT Live Server with SRTLA Support

This container provides an SRT (Secure Reliable Transport) Live Server with SRTLA support for reliable streaming over unreliable networks.

Features

• SRT protocol for low-latency streaming
• SRTLA support for connection bundling across multiple network paths
• HTTP API for statistics and monitoring
• HLS recording functionality
• Configurable via environment variables

Quick Start

docker run -d \
  -p 8181:8181 \
  -p 8080:8080/udp \
  -p 5000:5000/udp \
  -v /path/to/recordings:/tmp/mov/sls \
  -e SLS_RECORD_HLS=on \
  --name srt-live-server \
  ghcr.io/letsplaybar/srt-live-server:latest

Configuration

The server is configured using environment variables:

Variable	Default	Description
SLS_HTTP_PORT	8181	HTTP server port for API and VOD
SLS_SRT_PORT	8080	SRT server port
SLS_LATENCY	20	Latency in ms
SLS_DOMAIN_PLAYER	live.sls	Domain for player
SLS_DOMAIN_PUBLISHER	uplive.sls	Domain for publisher
SLS_RECORD_HLS	off	Enable HLS recording (on/off)
SLS_RECORD_HLS_PATH	/tmp/mov/sls	Path for HLS recordings
SRTLA_PORT	5000	SRTLA port for connection bundling

Docker Volumes

It's recommended to mount the following volumes:

• /logs: For server logs
• /tmp/mov/sls: For HLS recordings

Kubernetes Deployment with Helm

Prerequisites

• Kubernetes cluster
• Helm v3+
• cert-manager (for TLS/HTTPS)

Installation

# Pull the Helm chart from GitHub Container Registry
helm install srt-server oci://ghcr.io/letsplaybar/chart/srt-live-server --version <version> -f my-values.yaml

Helm Configuration

Key configuration parameters in values.yaml:

Parameter	Description	Default
replicaCount	Number of server replicas	1
image.repository	Docker image repository	ghcr.io/letsplaybar/srt-live-server
image.tag	Docker image tag	latest
udpService.type	Service type for UDP ports	LoadBalancer
ingress.enabled	Enable ingress for HTTP	true
ingress.hosts	Hostnames for ingress	["example.com"]

Networking

• UDP Service: Exposes SRT (8080/UDP) and SRTLA (5000/UDP) ports
• HTTP Service: Internal service for the HTTP interface
• Ingress: HTTP/HTTPS access with TLS support

TLS/HTTPS Configuration

The Helm chart supports automatic TLS certificate management via cert-manager. Configure it in your values.yaml:

ingress:
  annotations:
    cert-manager.io/cluster-issuer: "letsencrypt-cluster-issuer"
  tls:
    - secretName: srt-live-server-tls
      hosts:
        - "your-domain.com"
