Constants

 
D3D12_VIDEO_ENCODER_RATE_CONTROL_MODE_ABSOLUTE_QP_MAP
No rate control budgeting. Each EncodeFrame call will interpret the the QP values in the pRateControlQPMap field of the D3D12_VIDEO_ENCODER_PICTURE_CONTROL_CODEC_DATA_H264 or D3D12_VIDEO_ENCODER_PICTURE_CONTROL_CODEC_DATA_HEVC structure as a map of absolute QP values.
D3D12_VIDEO_ENCODER_RATE_CONTROL_MODE_CQP
Constant quantization parameter rate control mode.
D3D12_VIDEO_ENCODER_RATE_CONTROL_MODE_CBR
Constant bit rate rate control mode.
D3D12_VIDEO_ENCODER_RATE_CONTROL_MODE_VBR
Variable bit rate control mode.
D3D12_VIDEO_ENCODER_RATE_CONTROL_MODE_QVBR
Constant quality target rate variable rate control mode.
