PFND3D11_1DDI_GETVIDEODECODERBUFFERINFO callback function (d3d10umddi.h)
Queries the description of a video decoder buffer for a specified video operation.
Syntax
PFND3D11_1DDI_GETVIDEODECODERBUFFERINFO Pfnd3d111DdiGetvideodecoderbufferinfo;
void Pfnd3d111DdiGetvideodecoderbufferinfo(
D3D10DDI_HDEVICE unnamedParam1,
const D3D11_1DDI_VIDEO_DECODER_DESC *unnamedParam2,
UINT unnamedParam3,
D3D11_1DDI_VIDEO_DECODER_BUFFER_INFO *unnamedParam4
)
{...}
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
Index [in]
The zero-based index of the video decoder buffer type that is used for the specified operation. The display miniport driver returns the maximum number of video decoder buffer types that are required for the operation through a call to its GetVideoDecoderBufferTypeCount function.
unnamedParam4
pInfo [out]
A pointer to a D3D11_1DDI_VIDEO_DECODER_BUFFER_INFO structure that describes the video decoder buffer.
Return value
None
Remarks
The Microsoft Direct3D runtime verifies that the pDecodeDesc and Index parameter data is valid before it calls the GetVideoDecoderBufferInfo function.
