} ;

Constants

 
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_FLAG_NONE
None.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_FLAG_USE_CONSTRAINED_INTRAPREDICTION
Forces the encoding of each intra-coded block with residual data only from other intra-coded blocks, i.e. not from inter-coded blocks, in the frame. Check for support in D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_CONSTRAINED_INTRAPREDICTION_SUPPORT. This refers to constrained_intra_pred_flag in the picture parameter set (PPS).
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_FLAG_USE_ADAPTIVE_8x8_TRANSFORM
Enables the usage of adaptive 8x8 transform. Please check for support in D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_ADAPTIVE_8x8_TRANSFORM_ENCODING_SUPPORT.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_FLAG_ENABLE_CABAC_ENCODING
Enables CABAC entropy coding. If turned off, will use CAVLC. Please check for support in D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_CABAC_ENCODING_SUPPORT.
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_H264_FLAG_ALLOW_REQUEST_INTRA_CONSTRAINED_SLICES
Allows the caller to request for each frame with a special flag in the picture control structure that the slices of such frame are coded independently from each other. This mode restricts the motion vector search range to the region box of the current slice, i.e. motion vectors outside the slice boundary can't be used.
