A -+ * stream is a wrapper around a proxy for a \ref pw_client_node with -+ * an adapter.

This is a PW_DIRECTION_INPUT stream. -+ * \li Produce a stream to PipeWire.

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.
