Windows Driver Kit DDI reference (nc-d3d10umddi-pfnd3d11_1ddi_getvideodecoderbuffertypecount)

PFND3D11_1DDI_GETVIDEODECODERBUFFERTYPECOUNT callback function

Description

Queries the number of buffer types that the display miniport driver requires to perform a specified decode operation.

Parameters

`unnamedParam1`

hDevice [in]

A handle to the display device (graphics context).

`unnamedParam2`

pDecodeDesc [in]

A pointer to a D3D11_1DDI_VIDEO_DECODER_DESC structure that specifies the video decoder operation.

`unnamedParam3`

pBufferTypeCount [out]

A pointer to a UINT value that specifies the maximum number of buffer types that the driver supports for the specified video decoder operation.

Remarks

The Microsoft Direct3D runtime verifies that the pDecodeDesc parameter data is valid before it calls the GetVideoDecoderBufferTypeCount function.
