  • Article

D3DWDDM2_0DDI_VIDEO_DECODER_BUFFER_DESC1 is used with VideoDecoderSubmitBuffers1 to submit one or more buffer for decoding.

Syntax

typedef struct D3DWDDM2_0DDI_VIDEO_DECODER_BUFFER_DESC1 {
  D3D10DDI_HRESOURCE                                   hResource;
  D3D11_1DDI_VIDEO_DECODER_BUFFER_TYPE                 BufferType;
  UINT                                                 DataOffset;
  UINT                                                 DataSize;
  void                                                 *pIV;
  UINT                                                 IVSize;
  D3DWDDM2_0DDI_VIDEO_DECODER_SUB_SAMPLE_MAPPING_BLOCK *pSubSampleMappingBlock;
  UINT                                                 SubSampleMappingCount;
} D3DWDDM2_0DDI_VIDEO_DECODER_BUFFER_DESC1;

Members

hResource

A handle to the resource object that was created through a call to CreateResource.

BufferType

The type of buffer, specified as a member of the D3D11_1DDI_VIDEO_DECODER_BUFFER_TYPE enumeration.

DataOffset

The offset of the relevant data from the beginning of the buffer, in bytes.

Important  This value must be zero.
 

DataSize

Size of the relevant data.

pIV

A pointer to a buffer that contains an initialization vector (IV) for encrypted data. If the decode buffer does not contain encrypted data, set this member to NULL.

IVSize

The size of the buffer specified in the pIV member. If pIV is NULL, set this member to zero.

pSubSampleMappingBlock

A pointer to an array of D3DWDDM2_0DDI_VIDEO_DECODER_SUB_SAMPLE_MAPPING_BLOCK structures, which indicate exactly which bytes in the decode buffer are encrypted and which are in the clear. If the decode buffer does not contain encrypted data, set this member to NULL.

Values in the sub sample mapping blocks are relative to the start of the decode buffer.

SubSampleMappingCount

The number of D3DWDDM2_0DDI_VIDEO_DECODER_SUB_SAMPLE_MAPPING_BLOCK structures specified in the pSubSampleMappingBlocks member. If pSubSampleMappingBLocks is NULL, set this member to zero.
