Description

The D3D12DDI_VIDEO_ENCODER_CODEC_AV1_QUANTIZATION_CONFIG_0095 structure contains configuration information related to the quantization settings within an AV1 video encoder.

Members

`BaseQIndex`

Related to AV1 syntax in quantization_params().

`YDCDeltaQ`

Related to AV1 syntax in quantization_params().

`UDCDeltaQ`

Related to AV1 syntax in quantization_params().

`UACDeltaQ`

Related to AV1 syntax in quantization_params().

`VDCDeltaQ`

Related to AV1 syntax in quantization_params().

`VACDeltaQ`

Related to AV1 syntax in quantization_params().

`UsingQMatrix`

Related to AV1 syntax in quantization_params().

`QMY`

Related to AV1 syntax in quantization_params().

`QMU`

Related to AV1 syntax in quantization_params().

`QMV`

Related to AV1 syntax in quantization_params().

Remarks

AV1 syntax separate_uv_delta_q will always be coded as 1.

AV1 syntax diff_uv_delta can be inferred if U and V AC/DC components are the same.

See D3D12 AV1 video encoding for more information.
