Override this member function to handle notification of a change of sample rate.

Remarks

This member function is called when a change to the rate has been made by a call to IMediaPosition::put_Rate.

Override this and change the rate of data sent; typically, this is by a call to CBaseInputPin::BeginFlush and CBaseInputPin::EndFlush, and then sending samples marked with new time stamps.
