# RTSP parameters
# Disable support for the RTSP protocol.
rtspDisable: no
# List of enabled RTSP transport protocols.
# UDP is the most performant, but doesn't work when there's a NAT/firewall 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, tcp]
# Encrypt handshakes 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".

# Address of the UDP/RTP listener. This is needed only when "udp" is in protocols.

###############################################
# Path parameters
# These settings are path-dependent, and the map key is the name of the path.
# 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.
paths:
all:
# Source of the stream. This can be:
# * publisher -> the stream is published by a RTSP or RTMP client
# * rtsp://existing-url -> the stream is pulled from another RTSP server / camera
# * rtsps://existing-url -> the stream is pulled from another RTSP server / camera with RTSPS
# * rtmp://existing-url -> the stream is pulled from another RTMP server / camera
# * rtmps://existing-url -> the stream is pulled from another RTMP server / camera with RTMPS
# * http://existing-url/stream.m3u8 -> the stream is pulled from another HLS server
# * https://existing-url/stream.m3u8 -> the stream is pulled from another HLS server with HTTPS
# * udp://ip:port -> the stream is pulled from UDP, by listening on the specified IP and port
# * redirect -> the stream is provided by another path or server
# * rpiCamera -> the stream is provided by a Raspberry Pi Camera
source: publisher
# If the source is an RTSP or RTSPS URL, this is the protocol that will be used to
# pull the stream. available values are "automatic", "udp", "multicast", "tcp".
sourceProtocol: automatic
# Tf the source is an RTSP or RTSPS URL, this allows to support sources that
# don't provide server ports or use random server ports. This is a security issue
# and must be used only when interacting with sources that require it.
sourceAnyPortEnable: no
# If the source is a RTSPS, RTMPS or HTTPS URL, and the source certificate is self-signed
# or invalid, you can provide the fingerprint of the certificate in order to
# validate it anyway. It can be obtained by running:
# openssl s_client -connect source_ip:source_port </dev/null 2>/dev/null | sed -n '/BEGIN/,/END/p' > server.crt
# openssl x509 -in server.crt -noout -fingerprint -sha256 | cut -d "=" -f2 | tr -d ':'
sourceFingerprint:
# If the source is an RTSP or RTMP URL, it will be pulled only when at least
# one reader is connected, saving bandwidth.
sourceOnDemand: no
# If sourceOnDemand is "yes", readers will be put on hold until the source is
# ready or until this amount of time has passed.
sourceOnDemandStartTimeout: 10s
# If sourceOnDemand is "yes", the source will be closed when there are no
# readers connected and this amount of time has passed.
sourceOnDemandCloseAfter: 10s
# If the source is "redirect", this is the RTSP URL which clients will be
# redirected to.
sourceRedirect:
# If the source is "publisher" and a client is publishing, do not allow another
# client to disconnect the former and publish in its place.
disablePublisherOverride: no
# If the source is "publisher" and no one is publishing, redirect readers to this
# path. It can be can be a relative path (i.e. /otherstream) or an absolute RTSP URL.
fallback:
# Username required to publish.
# SHA256-hashed values can be inserted with the "sha256:" prefix.
