# main TCP port for RoomService and RTC endpoint
# for production setups, this port should be placed behind a load balancer with TLS
port: 7880

# log level, valid values: debug, info, warning, error
log_level: info

# when redis is set, LiveKit will automatically operate in a fully distributed fashion
# clients could connect to any node and be routed to the same room
redis:
  address: redis.host:6379
#  username: myuser

# WebRTC configuration
rtc:
  # UDP ports to use for client traffic.
  # this port range should be open for inbound traffic on the firewall
  port_range_start: 50000
  port_range_end: 60000
  # when set, LiveKit enable WebRTC ICE over TCP when UDP isn't available
  # this port *cannot* be behind load balancer or TLS, and must be exposed on the node
  # WebRTC transports are encrypted and do not require additional encryption
  tcp_port: 7881
  # when set to true, attempts to discover the host's public IP via STUN
  # this is useful for cloud environments such as AWS & Google where hosts have an internal IP
  # that maps to an external one
  use_external_ip: true
  # when set, LiveKit will attempt to use a UDP mux so all UDP traffic goes through
  # a single port. This simplifies deployment, but mux will become an overhead for
  # highly trafficked deployments.
  # port_range_start & end must not be set for this config to take effect
  # udp_port: 7882
  # optional settings
#  # when using REMB, the max bitrate that the SFU would accept, defaults to 3Mbps

#  packet_buffer_size: 500
#  # optional STUN servers for LiveKit clients to use. Clients will be configured to use these STUN servers automatically.
#  # by default LiveKit clients use Google's public STUN servers
#  stun_servers:
#    - server1
#  # minimum amount of time between pli/fir rtcp packets being sent to an individual

#  # percentile to measure, a participant is considered active if it has exceeded the
#  # ActiveLevel more than MinPercentile% of the time
#  # defaults to 40
