VkVideoEncodeH265CapabilityFlagBitsKHR

Bits which may be set in VkVideoEncodeH265CapabilitiesKHR::flags, indicating the H.265 encoding capabilities supported, are:

• VK_VIDEO_ENCODE_H265_CAPABILITY_HRD_COMPLIANCE_BIT_KHR indicates if the implementation may be able to generate HRD compliant bitstreams if any of the nal_hrd_parameters_present_flag, vcl_hrd_parameters_present_flag, or sub_pic_hrd_params_present_flag members of StdVideoH265HrdFlags are set to 1 in the HRD parameters of the active VPS or active SPS, or if StdVideoH265SpsVuiFlags::vui_hrd_parameters_present_flag is set to 1 in the active SPS.
• VK_VIDEO_ENCODE_H265_CAPABILITY_PREDICTION_WEIGHT_TABLE_GENERATED_BIT_KHR indicates that if the weighted_pred_flag or the weighted_bipred_flag member of StdVideoH265PpsFlags is set to 1 in the active PPS when encoding a P picture or B picture, respectively, then the implementation is able to internally decide syntax for pred_weight_table, as defined in section 7.4.7.3 of the ITU-T H.265 Specification, and the application is not required to provide a weight table in the H.265 slice segment header parameters.
• VK_VIDEO_ENCODE_H265_CAPABILITY_ROW_UNALIGNED_SLICE_SEGMENT_BIT_KHR indicates that each slice segment in a frame with a single or multiple tiles per slice may begin or finish at any offset in a CTB row. If not supported, all slice segments in such a frame must begin at the start of a CTB row (and hence each slice segment must finish at the end of a CTB row). Also indicates that each slice segment in a frame with multiple slices per tile may begin or finish at any offset within the enclosing tile’s CTB row. If not supported, slice segments in such a frame must begin at the start of the enclosing tile’s CTB row (and hence each slice segment must finish at the end of the enclosing tile’s CTB row).
• VK_VIDEO_ENCODE_H265_CAPABILITY_DIFFERENT_SLICE_SEGMENT_TYPE_BIT_KHR indicates that when a frame is encoded with multiple slice segments, the implementation allows encoding each slice segment with a different StdVideoEncodeH265SliceSegmentHeader::slice_type specified in the H.265 slice segment header parameters. If not supported, all slice segments of the frame must be encoded with the same slice_type which corresponds to the picture type of the frame.
• VK_VIDEO_ENCODE_H265_CAPABILITY_B_FRAME_IN_L0_LIST_BIT_KHR indicates support for using a B frame as L0 reference, as specified in StdVideoEncodeH265ReferenceListsInfo::RefPicList0 in the H.265 picture information.
• VK_VIDEO_ENCODE_H265_CAPABILITY_B_FRAME_IN_L1_LIST_BIT_KHR indicates support for using a B frame as L1 reference, as specified in StdVideoEncodeH265ReferenceListsInfo::RefPicList1 in the H.265 picture information.
• VK_VIDEO_ENCODE_H265_CAPABILITY_PER_PICTURE_TYPE_MIN_MAX_QP_BIT_KHR indicates support for specifying different QP values in the members of VkVideoEncodeH265QpKHR.
• VK_VIDEO_ENCODE_H265_CAPABILITY_PER_SLICE_SEGMENT_CONSTANT_QP_BIT_KHR indicates support for specifying different constant QP values for each slice segment.
• VK_VIDEO_ENCODE_H265_CAPABILITY_MULTIPLE_TILES_PER_SLICE_SEGMENT_BIT_KHR indicates if encoding multiple tiles per slice segment, as defined in section 6.3.1 of the ITU-T H.265 Specification, is supported. If this capability flag is not present, then the implementation is only able to encode a single tile for each slice segment.
• VK_VIDEO_ENCODE_H265_CAPABILITY_MULTIPLE_SLICE_SEGMENTS_PER_TILE_BIT_KHR indicates if encoding multiple slice segments per tile, as defined in section 6.3.1 of the ITU-T H.265 Specification, is supported. If this capability flag is not present, then the implementation is only able to encode a single slice segment for each tile.
