Members

PredictionMode

Input parameter. A D3D12DDI_VIDEO_ENCODER_AV1_COMP_PREDICTION_TYPE_0095 enumeration that specifies the requested prediction mode to be used. The driver must return the output parameters assuming a frame will be encoded using this prediction mode in the picture params structure.

MaxUniqueReferencesPerFrame

Output parameter. Indicates how many unique reference frames in the DPB can be selected at the same time for a given frame from any of the reference types (LAST, ..., ALTREF, etc) in the picture control parameters from the DPB that the API Client manages. In other words, the maximum number distinct (and with ReconstructedPictureResourceIndex != 0xFF) entries in D3D12DDI_VIDEO_ENCODE_REFERENCE_FRAMES_0080.pSubresources[ReferenceFramesReconPictureDescriptors[ReferenceIndices[i]].ReconstructedPictureResourceIndex] for i in [0..7].

SupportedFrameTypes

Output parameter. A D3D12DDI_VIDEO_ENCODER_AV1_FRAME_TYPE_0095_FLAGS enumeration that specifies the supported frame types to be used in D3D12DDI_VIDEO_ENCODER_AV1_FRAME_TYPE_0095.

SupportedReferenceWarpedMotionFlags

Output parameter. A D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_WARPED_MOTION_TRANSFORMATION_0095_FLAGS enumeration that specifies the supported types to be used in D3D12DDI_VIDEO_ENCODER_AV1_REFERENCE_PICTURE_WARPED_MOTION_INFO_0095.TransformationType.
