Class Details

class Wp.ImplNode(**kwargs)

Bases:

Wp.Proxy, Wp.PipewireObject

Abstract:

No

Structure:

Wp.ImplNodeClass

A Wp.ImplNode allows running a node implementation (struct pw_impl_node) locally, loading the implementation from factory or wrapping a manually constructed pw_impl_node. This object can then be exported to PipeWire by requesting Wp.ProxyFeatures.PROXY_FEATURE_BOUND.

classmethod new_from_pw_factory(core, factory_name, properties)

Parameters:

• core (Wp.Core) – the wireplumber core

• factory_name (str) – the name of the pipewire factory

• properties (Wp.Properties or None) – properties to be passed to node constructor

Returns:

A new Wp.ImplNode wrapping the node that was constructed by the factory, or None if the factory does not exist or was unable to construct the node

Return type:

Wp.ImplNode or None

Constructs a new node, locally on this process, using the specified factory_name.

To export this node to the PipeWire server, you need to call Wp.Object.activate() requesting Wp.ProxyFeatures.PROXY_FEATURE_BOUND and wait for the operation to complete.

classmethod new_wrap(core, node)

Parameters:

• core (Wp.Core) – the wireplumber core

• node (object or None) – an existing pw_impl_node to wrap

Returns:

A new Wp.ImplNode wrapping node

Return type:

Wp.ImplNode

Constructs a node object from an existing pw_impl_node.
