Article
05/31/2018

The AllocSurfaceSize method allocates a new ISurface of a specific size. ISurface wraps an IDirect3DSurface9 interface. However, the recommended way to allocate a surface is described in the IMediaTransform::Process documentation.

Syntax

HRESULT AllocSurfaceSize(
  [in]  FORMAT_TYPE type,
        VIDEO_SIZE  *pSize,
  [out] ISurface    **ppBuffer
);

Parameters

type [in]: A FORMAT_TYPE value that specifies the type of surface to create.
pSize: A VIDEO_SIZE structure that specifies the size of the surface to allocate.
ppBuffer [out]: Pointer to an ISurface interface pointer that wraps a Direct3D video surface. The caller must release this interface when done with it.

Return value

The method returns an HRESULT of S_OK for success, or a standard COM error code for failure.

Remarks

If you do not know the exact size of the surface to allocate, use AllocSurface.
