-Subject: [PATCH] extensions: implement Endpoint & ClientEndpoint interfaces
-
-The ClientEndpoint interface allows session managers to register
-endpoint objects on pipewire.
-The Endpoint interface allows other clients to interact with
-endpoints provided by the session manager.
-
-Upstream-Status: Pending
