Remarks
This member function is called when a new start position has been requested by a call to IMediaPosition::put_CurrentPosition.
Override this and change the data sent; typically, this is by a call to CBaseInputPin::BeginFlush and CBaseInputPin::EndFlush, and then sending samples marked with new time stamps.
