CTransformOutputPin.CTransformOutputPin constructor

  • Artikkeli

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Constructor method.

Syntax

CTransformOutputPin(
   TCHAR            *pObjectName,
   CTransformFilter *pTransformFilter,
   HRESULT          *phr,
   LPCWSTR          pName
);

Parameters

pObjectName

String containing the debug name of the object. For more information, see CBaseObject.

pTransformFilter

Pointer to the filter that created this pin, which must be a CTransformFilter object.

phr

Pointer to a variable that receives an HRESULT value indicating the success or failure of the method. Initialize the value to S_OK before creating the object. The value is changed only if an error occurs.

pName

Wide-character string containing the pin name.

Remarks

The pName parameter specifies the pin name, which is returned by the IPin::QueryPinInfo method. However, the string is not used for the pin identifier. The pin identifier for this class is always "Out". For more information, see QueryId.
