D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CONFIGURATION_PARAMS_0080_2 structure (d3d12umddi.h)

  • Article

The D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CONFIGURATION_PARAMS_0080_2 structure contains rate control configuration mode-specific parameters.

Syntax

typedef struct D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CONFIGURATION_PARAMS_0080_2 {
  UINT  DataSize;
  union {
    const D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CQP_0080    *pConfiguration_CQP;
    const D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CBR_0080    *pConfiguration_CBR;
    const D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_VBR_0080    *pConfiguration_VBR;
    const D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_QVBR_0080_2 *pConfiguration_QVBR;
  };
} D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CONFIGURATION_PARAMS_0080_2;

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 constant 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.

Remarks

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

See D3D12 video encoding for general information.
