* <para>
* This plugin writes incoming data to a set of filedescriptors. The filedescriptors
* can be added to multifdsink by emiting the "add" signal. For each descriptor added
* the "client-added" signal will be called.
* </para>
* <para>
* Clients can be removed from multifdsink by emiting the "remove" signal. For each
* descriptor removed the "client-removed" signal will be called. The "client-removed"
* signal can also be fired when multifdsink decides that a client is not active anymore
* or, depending on the value of the "recover-policy" if the client is reading to slow.
* In all cases, multifdsink will never close a filedescriptor itself, the application
* has to do that itself, for example, in the "client-removed" signal callback.
* </para>
* <para>
* Multifdsink internally keeps a queue of the incomming 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.
* </para>
* <para>
* When adding a client to multifdsink, the "sync-method" property will define which
* buffer will be sent first to the client. Clients can be sent respectively the most
* recent buffer (which might not be decodable by the client when 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 burst-on-connect).
* </para>
* <para>
* 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 slow, data for that client will bunch up in multifdsink. Two properties
* control the amount of data (buffers) that is queued in multifdsink: "buffers-max"
* and "buffers-soft-max". A client with a lag of "buffers-max" is removed from
* multifdsink forcibly.
* </para>
* <para>
* A client with a lag of at least "buffers-soft-max" enters the recovery procedure
* which is controled with the "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 to the most recent
* keyframe in the buffer queue.
* </para>
* <para>
* multifdsink will synchronize on the clock before serving the buffers to the clients.
* </para>
* <para>
* Example pipeline:
* <programlisting>
* gst-launch -v videotestsrc ! multifdsink
* </programlisting>
* This pipeline will not do a lot since it is not possible from a gst-launch line
* to add filedescriptors to multifdsink.
