Broadcaster Service

The Broadcaster Service project provides an evironment for simulating a TV 3.0 service broadcasting.

Features

• Distributed implementation of TV 3.0 components in a microservices fashion
  • Broadcaster apps with video streaming
• MQTT-based
  • TV 3.0 transport layer signaling

Dependencies

• Mosquitto MQTT Broker
• Node JS
• FFmpeg

Environment

Required (server fails on boot if missing):

• MQTT_HOST : hostname of the MQTT broker (service name inside Docker)
• BCAST_HOSTNAME : hostname advertised in bcastEntryPackageUrl (must be the Docker service name so AoP can proxy to it via the internal DNS)

Optional (with defaults):

• PORT : HTTP server port (default 8081)
• BSID, EDUPLAY_SID, UFF_SID, WEBMEDIA_SID : fixed service IDs (default generated via cuid.slug at each restart, which leaves orphan retained topics)
• LOG_LEVEL : ERROR | INFO | DEBUG (default ERROR)

See .env.example for the full list.
