The CTransformInputPin class implements an input pin that is used by the CTransformFilter class.
Typically, you do not need to derive from this class. Most of the methods in this class call corresponding methods on the CTransformFilter class, which you can override. If you derive from this class, you must override the filter's CTransformFilter::GetPin method to create instances of your derived class.
Requirements
Header: Declared in Transfrm.h; include Streams.h.
Library: Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
