The SetMediaType method is called when the media type is set on one of the filter's pins.
virtual HRESULT SetMediaType( PIN_DIRECTION direction, const CMediaType *pmt );
Member of the PIN_DIRECTION enumerated type, specifying a pin on the filter (input or output).
Pointer to a CMediaType object that specifies the media type.
The CTransformInputPin::SetMediaType and CTransformOutputPin::SetMediaType methods call this method when a pin's media type is set. This method does nothing in the base class, but the derived class can override it.
