D3D12DDI_VIDEO_ENCODER_REFERENCE_PICTURE_DESCRIPTOR_H264_0080 structure (d3d12umddi.h)

The D3D12DDI_VIDEO_ENCODER_REFERENCE_PICTURE_DESCRIPTOR_H264_0080 structure represents a reference picture descriptor for H.264 video encoding.

Syntax

typedef struct D3D12DDI_VIDEO_ENCODER_REFERENCE_PICTURE_DESCRIPTOR_H264_0080 {
  UINT ReconstructedPictureResourceIndex;
  BOOL IsLongTermReference;
  UINT LongTermPictureIdx;
  UINT PictureOrderCountNumber;
  UINT FrameDecodingOrderNumber;
  UINT TemporalLayerIndex;
} D3D12DDI_VIDEO_ENCODER_REFERENCE_PICTURE_DESCRIPTOR_H264_0080;

Members

ReconstructedPictureResourceIndex

Maps the current reference picture described by this structure to a resource in the D3D12DDI_VIDEO_ENCODER_PICTURE_CONTROL_DESC_0082_0.ReferenceFrames array.

IsLongTermReference

Set when the described reference frame is being used as a long-term reference picture.

LongTermPictureIdx

If IsLongTermReference is set, this value specifies the long-term reference index number.

PictureOrderCountNumber

Indicates the described reference frame display order.

FrameDecodingOrderNumber

The frame decode order with semantics as indicated by the slice header framenum* syntax element associated with the encoded reference picture.

TemporalLayerIndex

Picture layer number in temporal hierarchy. Check D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_HEVC_0082_0 for the maximum number of layers.

Remarks

See D3D12 video encoding for general information.
