Let the player graph run at the maximal speed
property UseClock: Boolean read GetUseClock write SetUseClock;
__property bool UseClock=read=GetUseClock, write=SetUseClock, nodefault
Property UseClock As Boolean
The speed of the player graph is under control of the renderer (video renderer, audio renderer, streaming, etc).
Disabling UseClock lets the player run at maximal speed.
This is used mainly e.g. to play a clip at the processing speed, e.g. to analyse the video frames without dropping any of them because of the player speed.
