Remarks
This member function is called when a new start position has been requested by a call to CSourceSeeking::SetPositions.
Override this and change the data sent.
Typically, you do this by calling CBaseInputPin::BeginFlush and CBaseInputPin::EndFlush, and then send samples marked with new start time (for example, with an implementation NewSegment method).
