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.

IsRefUsedByCurrentPic

Set when this descriptor entry is being used by the current picture by being indexed from the L0 and/or L1 lists.

IsLongTermReference

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

PictureOrderCountNumber

Indicates the described reference frame display order.

TemporalLayerIndex

Picture layer number in temporal hierarchy. Check D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_0082_0 for the maximum number of layers.

Remarks
