Syntax
typedef enum D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080 {
D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080_ABSOLUTE_QP_MAP,
D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080_CQP,
D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_MODE_0080_CBR,

} ;
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. |
