Windows Driver Kit DDI reference (ns-d3d12umddi-d3d12ddi_video_encoder_reference_picture_descriptor_h264_0080)

Description

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

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.
