  • Article

The D3DDDIARG_DECODEEXECUTE structure describes a Microsoft DirectX Video Acceleration (VA) decode operation to perform.

Syntax

typedef struct _D3DDDIARG_DECODEEXECUTE {
  [in] HANDLE                   hDecode;
  [in] UINT                     NumCompBuffers;
  [in] DXVADDI_DECODEBUFFERDESC *pCompressedBuffers;
} D3DDDIARG_DECODEEXECUTE;

Members

[in] NumCompBuffers

The number of compressed buffer that are pointed to by the pCompressedBuffers member.

[in] pCompressedBuffers

A pointer to a list of DXVADDI_DECODEBUFFERDESC structures that describe the compressed buffers that are passed from the host decoder to the accelerator.
