+ *
+ * \section page_registry_overview Overview
+ *
+ * The registry object is a singleton object that keeps track of
+ * global objects on the PipeWire instance. See also \ref page_global.
+ *
+ * Global objects typically represent an actual object in PipeWire
+ * (for example, a module or node) or they are singleton
+ * objects such as the core.
+ *
+ * When a client creates a registry object, the registry object
+ * will emit a global event for each global currently in the
+ * registry. Globals come and go as a result of device hotplugs or
+ * reconfiguration or other events, and the registry will send out
+ * global and global_remove events to keep the client up to date
+ * with the changes. To mark the end of the initial burst of
+ * events, the client can use the pw_core.sync methosd immediately
+ * after calling pw_core.get_registry.
+ *
+ * A client can bind to a global object by using the bind
+ * request. This creates a client-side proxy that lets the object
+ * emit events to the client and lets the client invoke methods on
+ * the object. See \ref page_proxy
+ *
+ * Clients can also change the permissions of the global objects that
+ * it can see. This is interesting when you want to configure a
+ * pipewire session before handing it to another application. You
+ * can, for example, hide certain existing or new objects or limit
+ * the access permissions on an object.

+/** \mainpage
+ *
+ * \section sec_intro Introduction
+ *
+ * This document describes the API for the PipeWire multimedia framework.
+ * The API consists of two parts:
+ *
+ * \li The core API to access a PipeWire instance.
+ * (See \subpage page_core_api)
+ * \li The implementation API and tools to build new objects and
+ * modules (See \subpage page_implementation_api)
+ *
+ * \section sec_errors Error reporting
+ *
+ * Functions return either NULL with errno set or a negative int error
+ * code when an error occurs. Error codes are used from the SPA plugin
+ * library on which PipeWire is built.
+ *
+ * Some functions might return asynchronously. The error code for such
+ * functions is positive and SPA_RESULT_IS_ASYNC() will return true.
+ * SPA_RESULT_ASYNC_SEQ() can be used to get the unique sequence number
+ * associated with the async operation.
+ *
+ * The object returning the async result code will have some way to
+ * signal the completion of the async operation (with, for example, a
+ * callback). The sequence number can be used to see which operation
+ * completed.
+ *
+ * \section sec_logging Logging
+ *
+ * The 'PIPEWIRE_DEBUG' environment variable can be used to enable
+ * more debugging. The format is:
+ *
+ * &lt;level&gt;[:&lt;category&gt;,...]
+ *
+ * - &lt;level&gt;: specifies the log level:
+ * + `0`: no logging is enabled
+ * + `1`: Error logging is enabled
+ * + `2`: Warnings are enabled
+ * + `3`: Informational messages are enabled
+ * + `4`: Debug messages are enabled
+ * + `5`: Trace messages are enabled. These messages can be logged
+ * from the realtime threads.
+ *
+ * - &lt;category&gt;: Specifies a string category to enable. Many categories
+ * can be separated by commas. Current categories are:
+ * + `connection`: to log connection messages

+/** \page page_proxy Proxy
+ *
+ * \section sec_page_proxy_overview Overview
+ *
+ * The proxy object is a client side representation of a resource
+ * that lives on a remote PipeWire instance.
+ *
+ * It is used to communicate with the remote object.
+ *
+ * \section sec_page_proxy_core Core proxy
+ *
+ * A proxy for a remote core object can be obtained by making
+ * a remote connection with \ref pw_core_connect.
+ * See \ref pw_page_remote_api
+ *
+ * Some methods on proxy object allow creation of more proxy objects or
+ * create a binding between a local proxy and global resource.
+ *
+ * \section sec_page_proxy_create Create
+ *
+ * A client first creates a new proxy object with pw_proxy_new(). A
+ * type must be provided for this object.
+ *
+ * The protocol of the context will usually install an interface to
+ * translate method calls and events to the wire format.
+ *
+ * The creator of the proxy will usually also install an event
+ * implementation of the particular object type.
+ *
+ * \section sec_page_proxy_bind Bind
+ *
+ * To actually use the proxy object, one needs to create a server
+ * side resource for it. This can be done by, for example, binding
+ * to a global object or by calling a method that creates and binds
+ * to a new remote object. In all cases, the local id is passed to
+ * the server and is used to create a resource with the same id.
+ *
+ * \section sec_page_proxy_methods Methods
+ *
+ * To call a method on the proxy use the interface methods. Calling
+ * any interface method will result in a request to the server to
+ * perform the requested action on the corresponding resource.
+ *
+ * \section sec_page_proxy_events Events
+ *
+ * Events send from the server to the proxy will be demarshalled by
+ * the protocol and will then result in a call to the installed
+ * implementation of the proxy.
+ *
+ * \section sec_page_proxy_destroy Destroy
+ *
+ * Use pw_proxy_destroy() to destroy the client side object. This
+ * is usually done automatically when the server removes the resource
+ * associated to the proxy.
+ */
+
+/** \class pw_proxy

+/** \page page_streams Media Streams
+ *
+ * \section sec_overview Overview
+ *
+ * Media streams are used to exchange data with the PipeWire server. A
+ * stream is a wrapper around a proxy for a \ref pw_client_node with
+ * an adapter. This means the stream will automatically do conversion
+ * to the type required by the server.
+ *
+ * Streams can be used to:
+ *
+ * \li Consume a stream from PipeWire. This is a PW_DIRECTION_INPUT stream.
+ * \li Produce a stream to PipeWire. This is a PW_DIRECTION_OUTPUT stream
+ *
+ * You can connect the stream port to a specific server port or let PipeWire
+ * choose a port for you.
+ *
+ * For more complicated nodes such as filters or ports with multiple
+ * inputs and/or outputs you will need to use the pw_filter or make
+ * a pw_node yourself and export it with \ref pw_core_export.
+ *
+ * \section sec_create Create
+ *
+ * Make a new stream with \ref pw_stream_new(). You will need to specify
+ * a name for the stream and extra properties. You can use \ref
+ * pw_fill_stream_properties() to get a basic set of properties for the
+ * stream.
+ *
+ * Once the stream is created, the state_changed event should be used to
+ * track the state of the stream.
+ *
+ * \section sec_connect Connect
+ *
+ * The stream is initially unconnected. To connect the stream, use
+ * \ref pw_stream_connect(). Pass the desired direction as an argument.
+ *
+ * \subsection ssec_stream_target Stream target
+ *
+ * To make the newly connected stream automatically connect to an existing
+ * PipeWire node, use the \ref PW_STREAM_FLAG_AUTOCONNECT and the port_path
+ * argument while connecting.
+ *
+ * \subsection ssec_stream_formats Stream formats
+ *
+ * An array of possible formats that this stream can consume or provide
+ * must be specified.
+ *
+ * \section sec_format Format negotiation
+ *
+ * After connecting the stream, the server will want to configure some
+ * parameters on the stream. You will be notified of these changes
+ * with the param_changed event.
+ *
+ * When a format param change is emitted, the client should now prepare
+ * itself to deal with the format and complete the negotiation procedure
+ * with a call to \ref pw_stream_update_params().
+ *
+ * As arguments to \ref pw_stream_update_params() an array of spa_param
+ * structures must be given. They contain parameters such as buffer size,
+ * number of buffers, required metadata and other parameters for the
+ * media buffers.
+ *
+ * \section sec_buffers Buffer negotiation
+ *
+ * After completing the format negotiation, PipeWire will allocate and
+ * notify the stream of the buffers that will be used to exchange data
+ * between client and server.
+ *
+ * With the add_buffer event, a stream will be notified of a new buffer
+ * that can be used for data transport. You can attach user_data to these
+ * buffers.
+ *
+ * After the buffers are negotiated, the stream will transition to the
+ * \ref PW_STREAM_STATE_PAUSED state.
+ *
+ * \section sec_streaming Streaming
+ *
+ * From the \ref PW_STREAM_STATE_PAUSED state, the stream can be set to
+ * the \ref PW_STREAM_STATE_STREAMING state by the PipeWire server when
+ * data transport is started.
+ *
+ * Depending on how the stream was connected it will need to Produce or
+ * Consume data for/from PipeWire as explained in the following
+ * subsections.
+ *
+ * \subsection ssec_consume Consume data
+ *
+ * The process event is emitted for each new buffer that can can be
+ * consumed.
+ *
+ * \ref pw_stream_dequeue_buffer() should be used to get the data and
+ * metadata of the buffer.
+ *
+ * When the buffer is no longer in use, call \ref pw_stream_queue_buffer()
+ * to let PipeWire reuse the buffer.
+ *
+ * \subsection ssec_produce Produce data
+ *
+ * \ref pw_stream_dequeue_buffer() gives an empty buffer that can be filled.
+ *
+ * Filled buffers should be queued with \ref pw_stream_queue_buffer().
+ *
+ * The process event is emitted when PipeWire has emptied a buffer that
+ * can now be refilled.
+ *
+ * \section sec_stream_disconnect Disconnect
+ *
+ * Use \ref pw_stream_disconnect() to disconnect a stream after use.

+/** \page page_thread_loop Threaded Loop
+ *
+ * \section sec_thread_loop_overview Overview
+ *
+ * The threaded loop implementation is a special wrapper around the
+ * regular \ref pw_loop implementation.
+ *
+ * The added feature in the threaded loop is that it spawns a new thread
+ * that runs the wrapped loop. This allows a synchronous application to use
+ * the asynchronous API without risking to stall the PipeWire library.
+ *
+ * \section sec_thread_loop_create Creation
+ *
+ * A \ref pw_thread_loop object is created using pw_thread_loop_new().
+ * The \ref pw_loop to wrap must be given as an argument along with the name
+ * for the thread that will be spawned.
+ *
+ * After allocating the object, the thread must be started with
+ * pw_thread_loop_start()
+ *
+ * \section sec_thread_loop_destruction Destruction
+ *
+ * When the PipeWire connection has been terminated, the thread must be
+ * stopped and the resources freed. Stopping the thread is done using
+ * pw_thread_loop_stop(), which must be called without the lock (see
+ * below) held. When that function returns, the thread is stopped and the
+ * \ref pw_thread_loop object can be freed using pw_thread_loop_destroy().
+ *
+ * \section sec_thread_loop_locking Locking
+ *
+ * Since the PipeWire API doesn't allow concurrent accesses to objects,
+ * a locking scheme must be used to guarantee safe usage. The threaded
+ * loop API provides such a scheme through the functions
+ * pw_thread_loop_lock() and pw_thread_loop_unlock().
+ *
+ * The lock is recursive, so it's safe to use it multiple times from the same
+ * thread. Just make sure you call pw_thread_loop_unlock() the same
+ * number of times you called pw_thread_loop_lock().
+ *
+ * The lock needs to be held whenever you call any PipeWire function that
+ * uses an object associated with this loop. Make sure you do not hold
+ * on to the lock more than necessary though, as the threaded loop stops
+ * while the lock is held.
+ *
+ * \section sec_thread_loop_events Events and Callbacks
+ *
+ * All events and callbacks are called with the thread lock held.
+ *
+ */
