Windows Driver Kit DDI reference (ne-d3d12umddi-d3d12ddi_video_encoder_rate_control_mode_0080)

Description

The D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080 enumeration lists the possible rate control modes.

Constants

`D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080_ABSOLUTE_QP_MAP`

Indicates no rate control budgeting. Each EncodeFrame call will interpret the quantization parameter (QP) values in pRateControlQPMap as a map of absolute values.

`D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080_CQP`

Indicates constant quantization parameter (CQP) rate control mode.

`D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080_CBR`

Indicates constant bit rate (CBR) rate control mode.

`D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080_VBR`

Indicates variable bit rate (VBR) rate control mode.

`D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080_QVBR`

Indicates constant quality target rate variable bit rate (QVBR) rate control mode.

Remarks

See D3D12 video encoding for general information.
