libpipewire-module-protocol-native - Man Page

The native protocol module implements the PipeWire communication between a client and a server using unix local sockets.

Normally this module is loaded in both client and server config files so that they cam communicate.

libpipewire-module-protocol-native

The module supports the following arguments:

• sockets: [ { name = 'socket-name', owner = 'owner', group = 'group', mode = 'mode', selinux.context = 'context' }, ... ]

Array of Unix socket names and (optionally) owner/permissions to serve, if the context is a server. If not absolute paths, the sockets are created in the default runtime directory.

Has the default value [ { name = 'CORENAME' }, { name = 'CORENAME-manager' } ], where CORENAME is the name of the PipeWire core, usually pipewire-0.

The permissions have no effect for sockets from Systemd socket activation. Those should be configured via the systemd.socket(5) mechanism.

The name of the core is obtained as:

• PIPEWIRE_CORE : the environment variable with the name of the core
• core.name : in the context properties
• a name based on the process id

The context will also become a server if:

• PIPEWIRE_DAEMON : the environment is true
• core.daemon : in the context properties is true

The socket will be located in the directory obtained by looking at the following environment variables:

• PIPEWIRE_RUNTIME_DIR
• XDG_RUNTIME_DIR
• USERPROFILE

The socket address will be written into the notification file descriptor if the following environment variable is set:

• PIPEWIRE_NOTIFICATION_FD

When a client connect, the connection will be made to:

• PIPEWIRE_REMOTE : the environment with the remote name
• remote.name : the property in the context.
• The default remote named 'pipewire-0'

A Special remote named 'internal' can be used to make a connection to the local context. This can be done even when the server is not a daemon. It can be used to treat a local context as if it was a server.
