} ;

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.
