CTransformFilter::SetMediaType

The SetMediaType method is called when the media type is set on one of the filter's pins.

Syntax

  virtual HRESULT SetMediaType(
    PIN_DIRECTION direction,
    const CMediaType *pmt
);

Parameters

direction

Member of the PIN_DIRECTION enumerated type, specifying a pin on the filter (input or output).

pmt

Pointer to a CMediaType object that specifies the media type.

Return Value

Returns S_OK.

Remarks

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.

Requirements

**  Header:** Declared in Transfrm.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
