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