Comments

This is an optional function that performs time consuming initialization, allowing immediate execution with StartCapture. If this function is used, it must be called prior to calling StartCapture. However, you may call StartCapture without calling ReadyCapture, but capturing will not begin immediately. Places the object in the ltmfCapture_State_Pending state.
