/** \page page_api PipeWire API
|
|
|
|
The PipeWire API consists of several parts:
|
|
|
|
- The \ref pw_stream for a convenient way to send and receive data streams from/to PipeWire.
|
|
|
|
- The \ref pw_filter for a convenient way to implement processing filters.
|
|
|
|
- The \ref api_pw_core to access a PipeWire instance. This API is used
|
|
by all clients that need to communicate with the \ref page_daemon and provides
|
|
the necessary structs to interface with the daemon.
|
|
|
|
- The \ref api_pw_impl is primarily used by the \ref page_daemon itself but also by the
|
|
\ref page_session_manager and modules/extensions that need to build objects in
|
|
the graph.
|
|
|
|
- The \ref api_pw_util containing various utility functions and structures.
|
|
|
|
- The \ref api_pw_ext for interfacing with certain extension modules.
|
|
|
|
The APIs work through proxy objects, so that calling a method on an object
|
|
invokes that same method on the remote side. Marshalling and de-marshalling is
|
|
handled transparently by the \ref page_module_protocol_native.
|
|
The below graph illustrates this approach:
|
|
|
|
\dot
|
|
digraph API {
|
|
compound=true;
|
|
node [shape="box"];
|
|
rankdir="RL";
|
|
|
|
subgraph cluster_daemon {
|
|
rankdir="TB";
|
|
label="PipeWire daemon";
|
|
style="dashed";
|
|
|
|
impl_core [label="Core Impl. Object"];
|
|
impl_device [label="Device Impl. Object"];
|
|
impl_node [label="Node Impl. Object"];
|
|
}
|
|
|
|
subgraph cluster_client {
|
|
rankdir="TB";
|
|
label="PipeWire client";
|
|
style="dashed";
|
|
|
|
obj_core [label="Core Object"];
|
|
obj_device [label="Device Object"];
|
|
obj_node [label="Node Object"];
|
|
}
|
|
|
|
obj_core -> impl_core;
|
|
obj_device -> impl_device;
|
|
obj_node -> impl_node;
|
|
|
|
}
|
|
\enddot
|
|
|
|
It is common for clients to use both the \ref api_pw_core and the \ref api_pw_impl
|
|
and both APIs are provided by the same library.
|
|
|
|
- \subpage page_client_impl
|
|
- \subpage page_proxy
|
|
- \subpage page_streams
|
|
- \subpage page_thread_loop
|
|
|
|
|
|
\addtogroup api_pw_core Core API
|
|
|
|
The Core API to access a PipeWire instance. This API is used by all
|
|
clients to communicate with the \ref page_daemon.
|
|
|
|
If you are familiar with Wayland implementation, the Core API is
|
|
roughly equivalent to libwayland-client.
|
|
|
|
See: \ref page_api
|
|
|
|
|
|
\addtogroup api_pw_impl Implementation API
|
|
|
|
The implementation API provides the tools to build new objects and
|
|
modules.
|
|
|
|
If you are familiar with Wayland implementation, the Implementation API is
|
|
roughly equivalent to libwayland-server.
