The Run method runs the filter. This method implements the IMediaFilter::Run method.
HRESULT Run( REFERENCE_TIME tStart );
Reference time corresponding to stream time 0.
Returns S_OK if successful, or an HRESULT value indicating the cause of the error.
If the filter is stopped, this method pauses the filter by calling the CBaseFilter::Pause method. It then calls the CBasePin::Run method on each of the filter's connected pins. Finally, it sets the CBaseFilter::m_State member variable to State_Running.
Stream time is calculated as the current reference time minus tStart. A media sample with a time stamp of zero should be rendered at time tStart.
