Syntax

HRESULT CreateVideoDecoder(
  [in]  REFGUID                         Guid,
  [in]  const DXVA2_VideoDesc           *pVideoDesc,
  [in]  const DXVA2_ConfigPictureDecode *pConfig,
  [in]  IDirect3DSurface9               **ppDecoderRenderTargets,
  [in]  UINT                            NumRenderTargets,
  [out] IDirectXVideoDecoder            **ppDecode
);

Parameters

[in] Guid

GUID that specifies the decoder device to create. To get the available device GUIDs, call IDirectXVideoDecoderService::GetDecoderDeviceGuids.

[in] pVideoDesc

Pointer to a DXVA2_VideoDesc structure that describes the video content.

[in] pConfig

Pointer to a DXVA2_ConfigPictureDecode structure that specifies the decoder configuration.

[in] ppDecoderRenderTargets

Pointer to an array of IDirect3DSurface9 pointers containing pointers to the decoder render targets. To create these surfaces, call IDirectXVideoAccelerationService::CreateSurface. Specify DXVA2_VideoDecoderRenderTarget for the DxvaType parameter.

[in] NumRenderTargets

Size of the ppDecoderRenderTargets array. This value cannot be zero.

[out] ppDecode

Receives a pointer to the decoder's IDirectXVideoDecoder interface. The caller must release the interface.
