_D3DDDIARG_DECODEEXTENSIONEXECUTE structure

Description

The D3DDDIARG_DECODEEXTENSIONEXECUTE structure describes a nonstandard Microsoft DirectX Video Acceleration (VA) decode operation to perform.

Members

hDecode [in]

A handle to the DirectX VA decode device. The user-mode display driver returns this handle in a call to its CreateDecodeDevice function.

Function [in]

A specific decode operation to perform. The possible values for this member are defined by the nonstandard decode device.

pPrivateInput [in]

A pointer to a DXVADDI_PRIVATEDATA structure that contains data that the driver requires to perform the decode operation.

pPrivateOutput [out]

A pointer to a DXVADDI_PRIVATEDATA structure that contains data about the decode operation that the driver returns.

NumBuffers [in]

The number of buffers in the list that is pointed to by pBuffers.

pBuffers

[in] A pointer to a list of DXVADDI_PRIVATEBUFFER structures that describe private buffers that a nonstandard decoder uses to perform a decode operation.
