D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095 enumeration (d3d12umddi.h)

  • Article

The D3D12_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS enumeration defines the list of distinct interpolation filter types that can be used in the AV1 video encoding process, where each value represents a specific interpolation filter.

Syntax

typedef enum D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095 {
  D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_EIGHTTAP = 0,
  D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_EIGHTTAP_SMOOTH = 1,
  D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_EIGHTTAP_SHARP = 2,
  D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_BILINEAR = 3,
  D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_SWITCHABLE = 4
} ;

Constants

 
D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_EIGHTTAP
Value: 0
The eight-tap interpolation filter uses eight samples to create a prediction.
D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_EIGHTTAP_SMOOTH
Value: 1
The eight-tap smooth interpolation filter is a variant of the eight-tap filter that applies a smoothing function to reduce sharpness.
D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_EIGHTTAP_SHARP
Value: 2
The eight-tap sharp interpolation filter is another variant of the eight-tap filter that emphasizes sharpness.
D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_BILINEAR
Value: 3
The bilinear interpolation filter uses two samples to create a prediction.
D3D12DDI_VIDEO_ENCODER_AV1_INTERPOLATION_FILTERS_0095_SWITCHABLE
Value: 4
The encoder has the capability to dynamically switch between different interpolation filters based on the content of each block. Instead of using a single filter for the entire video frame, the encoder can choose the most appropriate filter for each block to optimize quality and compression efficiency.
