Members

DataSize

Size of the referenced data, in bytes.

pConfiguration_CQP

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CQP_0080 structure that contains the rate control structure definition for constant quantization parameter (CQP) mode.

pConfiguration_CBR

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CBR_0080 structure that contains the rate control structure definition for constant bitrate (CBR) mode.

pConfiguration_VBR

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_VBR_0080 structure that contains the rate control structure definition for variable bitrate (VBR) mode.

pConfiguration_QVBR

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_QVBR_0080_2 structure that contains the rate control structure definition for constant quality target with constrained (variable) bitrate (QVBR) mode.

pConfiguration_CQP1

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CQP1_0096 structure that contains the extended rate control structure definition for constant quantization parameter (CQP) mode. Available starting with Windows 11, version 24H2 (WDDM 3.2).

pConfiguration_CBR1

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CBR1_0096 structure that contains the extended rate control structure definition for constant bitrate (CBR) mode. Available starting with Windows 11, version 24H2 (WDDM 3.2).

pConfiguration_VBR1

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_VBR1_0096 structure that contains the extended rate control structure definition for variable bitrate (VBR) mode. Available starting with Windows 11, version 24H2 (WDDM 3.2).

pConfiguration_QVBR1

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_QVBR1_0096 structure that contains the extended rate control structure definition for constant quality target with variable bitrate (QVBR) mode. Available starting with Windows 11, version 24H2 (WDDM 3.2).

pConfiguration_AbsoluteQPMap

Pointer to a D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_ABSOLUTE_QP_MAP_0096 structure that contains the rate control structure definition for absolute QP map mode. Available starting with Windows 11, version 24H2 (WDDM 3.2).

Remarks

The configuration mode-specific structure to use is based on the value of D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_0080_2.Mode.
