The rtp-sink module creates a PipeWire sink that sends audio RTP packets.

# Module Name

libpipewire-module-rtp-sink

# Module Options

Options specific to the behavior of this module

- source.ip =<str>: source IP address, default "0.0.0.0"
- destination.ip =<str>: destination IP address, default "224.0.0.56"
- destination.port =<int>: destination port, default random between 46000 and 47024
- local.ifname = <str>: interface name to use
- net.mtu = <int>: MTU to use, default 1280
- net.ttl = <int>: TTL to use, default 1
- net.loop = <bool>: loopback multicast, default false
- sess.min-ptime = <float>: minimum packet time in milliseconds, default 2
- sess.max-ptime = <float>: maximum packet time in milliseconds, default 20
- sess.name = <str>: a session name
- rtp.ptime = <float>: size of the packets in milliseconds, default up to MTU but between sess.min-ptime and sess.max-ptime
- rtp.framecount = <int>: number of samples per packet, default up to MTU but between sess.min-ptime and sess.max-ptime
- sess.latency.msec = <float>: target node latency in milliseconds, default as rtp.ptime
- sess.ts-offset = <int>: an offset to apply to the timestamp, default -1 = random offset
- sess.ts-refclk = <string>: the name of a reference clock
- sess.media = <string>: the media type audio|midi|opus, default audio
- stream.props = {}: properties to be passed to the stream
- aes67.driver-group = <string>: for AES67 streams, can be specified in order to allow the sink to be driven by a different node than the PTP driver.
