Constants
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_NONENone. |
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_CABAC_ENCODING_SUPPORTSupport for context-adaptive binary arithmetic coding (CABAC) encoding. |
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_INTRA_SLICE_CONSTRAINED_ENCODING_SUPPORTSupport for slice constrained encoding in which every slice in a frame is encoded independently from other slices in the same frame. This mode restricts the motion vector search range to the region box of the current slice, e.g. motion vectors outside the slice boundary can't be used. |
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_BFRAME_LTR_COMBINED_SUPPORTSupport for using B-frames and long term references at the same time. |
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_ADAPTIVE_8x8_TRANSFORM_ENCODING_SUPPORTSupport for using adaptive 8x8 transforms when encoding. |
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_DIRECT_SPATIAL_ENCODING_SUPPORTSupport for spatial direct mode. |
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_DIRECT_TEMPORAL_ENCODING_SUPPORTSupport for temporal direct mode. |
D3D12_VIDEO_ENCODER_CODEC_CONFIGURATION_SUPPORT_H264_FLAG_CONSTRAINED_INTRAPREDICTION_SUPPORTSupport for constrained intraprediction, that if activated will force the encoding of each intra-coded block with residual data only from other intra-coded blocks, e.g. not from inter-coded blocks. This refers to constrained_intra_pred_flag in the picture parameter set (PPS). |
