video clip. It is not possible to play the video clip or query any of its properties (e.g. duration, meta data etc.) until
the controller plugin has signified the completion of this method by generating a KMMFEventCategoryVideoPrepareComplete event.
Return value
GetFrame(CFbsBitmap &,TRequestStatus &)
