+-----------
+- operation:
+ - client fd gets added when "add" signal gets emitted on multifdsink
+ - signal handler creates a GstTCPClient structure, adds it to ->clients,
+ and adds the fd to ->fd_hash, then emits client-added
+ - client
+
+ - when a buffer comes in:
+ - the _render vmethod puts the buffer on the global queue
+ - and increases bytes_to_serve
+ - (currently it sets streamheaders, but since this is treated globally
+ this is wrong - clients can be at different positions in the stream)
+
+ - when a client issues a write (ie requests data):
+ - when using GDP, if no caps sent yet, send caps first, then set caps_sent
+ - if streamheader buffers, and we haven't sent yet to this client,
+ send current streamheader buffers, then set streamheader_sent
+ - send out buffers

+/**
+ * SECTION:element-multifdsink
+ * @see_also: tcpserversink
+ *
+ * This plugin writes incoming data to a set of file descriptors. The
+ * file descriptors can be added to multifdsink by emitting the #GstMultiFdSink::add signal.
+ * For each descriptor added, the #GstMultiFdSink::client-added signal will be called.
+ *
+ * As of version 0.10.8, a client can also be added with the #GstMultiFdSink::add-full signal
+ * that allows for more control over what and how much data a client
+ * initially receives.
+ *
+ * Clients can be removed from multifdsink by emitting the #GstMultiFdSink::remove signal. For
+ * each descriptor removed, the #GstMultiFdSink::client-removed signal will be called. The
+ * #GstMultiFdSink::client-removed signal can also be fired when multifdsink decides that a
+ * client is not active anymore or, depending on the value of the
+ * #GstMultiFdSink:recover-policy property, if the client is reading too slowly.
+ * In all cases, multifdsink will never close a file descriptor itself.
+ * The user of multifdsink is responsible for closing all file descriptors.
+ * This can for example be done in response to the #GstMultiFdSink::client-fd-removed signal.
+ * Note that multifdsink still has a reference to the file descriptor when the
+ * #GstMultiFdSink::client-removed signal is emitted, so that "get-stats" can be performed on
+ * the descriptor; it is therefore not safe to close the file descriptor in
+ * the #GstMultiFdSink::client-removed signal handler, and you should use the
+ * #GstMultiFdSink::client-fd-removed signal to safely close the fd.
+ *
+ * Multifdsink internally keeps a queue of the incoming buffers and uses a
+ * separate thread to send the buffers to the clients. This ensures that no
+ * client write can block the pipeline and that clients can read with different
+ * speeds.
+ *
+ * When adding a client to multifdsink, the #GstMultiFdSink:sync-method property will define
+ * which buffer in the queued buffers will be sent first to the client. Clients
+ * can be sent the most recent buffer (which might not be decodable by the
+ * client if it is not a keyframe), the next keyframe received in
+ * multifdsink (which can take some time depending on the keyframe rate), or the
+ * last received keyframe (which will cause a simple burst-on-connect).
+ * Multifdsink will always keep at least one keyframe in its internal buffers
+ * when the sync-mode is set to latest-keyframe.
+ *
+ * As of version 0.10.8, there are additional values for the #GstMultiFdSink:sync-method
+ * property to allow finer control over burst-on-connect behaviour. By selecting
+ * the 'burst' method a minimum burst size can be chosen, 'burst-keyframe'
+ * additionally requires that the burst begin with a keyframe, and
+ * 'burst-with-keyframe' attempts to burst beginning with a keyframe, but will
+ * prefer a minimum burst size even if it requires not starting with a keyframe.
+ *
+ * Multifdsink can be instructed to keep at least a minimum amount of data
+ * expressed in time or byte units in its internal queues with the the
+ * #GstMultiFdSink:time-min and #GstMultiFdSink:bytes-min properties respectively.
+ * These properties are useful if the application adds clients with the
+ * #GstMultiFdSink::add-full signal to make sure that a burst connect can
+ * actually be honored.
+ *
+ * When streaming data, clients are allowed to read at a different rate than
+ * the rate at which multifdsink receives data. If the client is reading too
+ * fast, no data will be send to the client until multifdsink receives more
+ * data. If the client, however, reads too slowly, data for that client will be
+ * queued up in multifdsink. Two properties control the amount of data
+ * (buffers) that is queued in multifdsink: #GstMultiFdSink:buffers-max and
+ * #GstMultiFdSink:buffers-soft-max. A client that falls behind by
+ * #GstMultiFdSink:buffers-max is removed from multifdsink forcibly.
+ *
+ * A client with a lag of at least #GstMultiFdSink:buffers-soft-max enters the recovery
+ * procedure which is controlled with the #GstMultiFdSink:recover-policy property.
+ * A recover policy of NONE will do nothing, RESYNC_LATEST will send the most recently
+ * received buffer as the next buffer for the client, RESYNC_SOFT_LIMIT
+ * positions the client to the soft limit in the buffer queue and
+ * RESYNC_KEYFRAME positions the client at the most recent keyframe in the
+ * buffer queue.
+ *
+ * multifdsink will by default synchronize on the clock before serving the
+ * buffers to the clients. This behaviour can be disabled by setting the sync
+ * property to FALSE. Multifdsink will by default not do QoS and will never
+ * drop late buffers.
