* 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.
*
* The multifdsink element needs to be set into READY, PAUSED or PLAYING state
* before operations such as adding clients are possible.
*
* 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.
