D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CQP_0080 structure (d3d12umddi.h)

The D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CQP_0080 structure contains the rate control definition for constant quantization parameter (CQP) mode.

Syntax

typedef struct D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CQP_0080 {
  UINT ConstantQP_FullIntracodedFrame;
  UINT ConstantQP_InterPredictedFrame_PrevRefOnly;
  UINT ConstantQP_InterPredictedFrame_BiDirectionalRef;
} D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_CQP_0080;

Members

ConstantQP_FullIntracodedFrame

The quantization parameter that should be used for each fully intra-encoded frame.

ConstantQP_InterPredictedFrame_PrevRefOnly

The quantization parameter that should be used for each encoded frame that has inter-picture references to pictures, in display order, before the current one.

ConstantQP_InterPredictedFrame_BiDirectionalRef

The quantization parameter that should be used for each encoded frame that has inter-picture references to pictures, in display order, both from the previous and next frames.

Remarks

See D3D12 video encoding for general information.
