Snapcast Discover

Automatically creates a Snapcast sink device based on zeroconf information.

This module will load module-protocol-simple for each announced stream that matches the rule with the create-stream action and passes the properties to the module.

If no stream.rules are given, it will create a sink for all announced snapcast servers.

A new stream will be created on the snapcast server with the given snapcast.stream-name or PipeWire-<hostname>. You will need to route this new stream to clients with the snapcast control application.

Module Name

libpipewire-module-snapcast-discover

Module Options

Options specific to the behavior of this module

• snapcast.discover-local = allow discovery of local services as well. false by default.
• stream.rules = <rules>: match rules, use create-stream actions. See Protocol Simple for module properties.

stream.rules matches

• snapcast.ip: the IP address of the snapcast server
• snapcast.port: the port of the snapcast server
• snapcast.ifindex: the interface index where the snapcast announcement was received.
• snapcast.ifname: the interface name where the snapcast announcement was received.
• snapcast.name: the name of the snapcast server
• snapcast.hostname: the hostname of the snapcast server
• snapcast.domain: the domain of the snapcast server

stream.rules create-stream

In addition to all the properties that can be passed to Protocol Simple, you can also set:

• snapcast.stream-name: The name of the stream on a snapcast server.
• node.name: The name of the sink that is created on the sender.
