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.
