Client Device

Allow clients to export devices to the PipeWire daemon.

This module creates an export type for the SPA_TYPE_INTERFACE_Device interface.

With pw_core_export(), objects of this type can be exported to the PipeWire server. All actions performed on the device locally will be visible to connecteced clients.

In some cases, it is possible to use this factory directly. With pw_core_create_object() on the client-device factory will result in a SPA_TYPE_INTERFACE_Device proxy that can be used to control the server side created Device Impl.

Schematically, the client side Device is wrapped in the ClientDevice proxy and unwrapped by the server side resource so that all actions on the client side device are reflected on the server side device and server side actions are reflected in the client.
