###############################################
# RTSP parameters
# disable support for the RTSP protocol.
rtspDisable: no
# supported RTSP stream protocols.
# UDP is the most performant, but can cause problems if there's a NAT between
# server and clients, and doesn't support encryption.
# UDP-multicast allows to save bandwidth when clients are all in the same LAN.
# TCP is the most versatile, and does support encryption.
# The handshake is always performed with TCP.
protocols: [udp, multicast, tcp]
# encrypt handshake and TCP streams with TLS (RTSPS).
# available values are "no", "strict", "optional".
encryption: no
# address of the TCP/RTSP listener. This is needed only when encryption is "no" or "optional".
rtspAddress: :8554
# address of the TCP/TLS/RTSPS listener. This is needed only when encryption is "strict" or "optional".
rtspsAddress: :8555
# address of the UDP/RTP listener. This is needed only when "udp" is in protocols.
rtpAddress: :8000
# address of the UDP/RTCP listener. This is needed only when "udp" is in protocols.
rtcpAddress: :8001
# IP range of all UDP-multicast listeners. This is needed only when "multicast" is in protocols.
multicastIPRange: 224.1.0.0/16
# port of all UDP-multicast/RTP listeners. This is needed only when "multicast" is in protocols.
multicastRTPPort: 8002
# port of all UDP-multicast/RTCP listeners. This is needed only when "multicast" is in protocols.
multicastRTCPPort: 8003
# path to the server key. This is needed only when encryption is "strict" or "optional".
# this can be generated with:
# openssl genrsa -out server.key 2048
# openssl req -new -x509 -sha256 -key server.key -out server.crt -days 3650

# read buffer size.
# this doesn't influence throughput and shouldn't be touched unless the server
# reports errors about the buffer size.

# RTMP parameters
# disable support for the RTMP protocol.
rtmpDisable: yes
# address of the RTMP listener.

###############################################
# HLS parameters
# disable support for the HLS protocol.
hlsDisable: yes
# address of the HLS listener.
hlsAddress: :8888
# number of HLS segments to generate.
# increasing segments allows more buffering,
# decreasing segments decrease latency.
hlsSegmentCount: 3
# minimum duration of each segment.
# the real segment duration is also influenced by the interval between IDR frames,
# since the server changes the segment duration to include at least one IDR frame in each.
hlsSegmentDuration: 1s
# value of the Access-Control-Allow-Origin header provided in every HTTP response.
# This allows to play the HLS stream from an external website.

# Path parameters
# these settings are path-dependent.
# it's possible to use regular expressions by using a tilde as prefix.
# for example, "~^(test1|test2)$" will match both "test1" and "test2".
# for example, "~^prefix" will match all paths that start with "prefix".
# the settings under the path "all" are applied to all paths that do not match
# another entry.
