Description

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

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.
