* This plugin writes incoming data to a set of file descriptors. The
* file descriptors can be added to multisocketsink by emitting the #GstMultiSocketSink::add signal.
* For each descriptor added, the #GstMultiSocketSink::client-added signal will be called.

* Clients can be removed from multisocketsink by emitting the #GstMultiSocketSink::remove signal. For
* each descriptor removed, the #GstMultiSocketSink::client-removed signal will be called. The
* #GstMultiSocketSink::client-removed signal can also be fired when multisocketsink decides that a
* client is not active anymore or, depending on the value of the
* #GstMultiSocketSink:recover-policy property, if the client is reading too slowly.
* In all cases, multisocketsink will never close a file descriptor itself.
* The user of multisocketsink is responsible for closing all file descriptors.
* This can for example be done in response to the #GstMultiSocketSink::client-fd-removed signal.
* Note that multisocketsink still has a reference to the file descriptor when the
* #GstMultiSocketSink::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 #GstMultiSocketSink::client-removed signal handler, and you should use the
* #GstMultiSocketSink::client-fd-removed signal to safely close the fd.

* When adding a client to multisocketsink, the #GstMultiSocketSink: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
* multisocketsink (which can take some time depending on the keyframe rate), or the
* last received keyframe (which will cause a simple burst-on-connect).
* Multisocketsink will always keep at least one keyframe in its internal buffers
* when the sync-mode is set to latest-keyframe.

* When streaming data, clients are allowed to read at a different rate than
* the rate at which multisocketsink receives data. If the client is reading too
* fast, no data will be send to the client until multisocketsink receives more
* data. If the client, however, reads too slowly, data for that client will be
* queued up in multisocketsink. Two properties control the amount of data
* (buffers) that is queued in multisocketsink: #GstMultiSocketSink:buffers-max and
* #GstMultiSocketSink:buffers-soft-max. A client that falls behind by
* #GstMultiSocketSink:buffers-max is removed from multisocketsink forcibly.
