Features pass to the external model to make partition decisions.

The encoder sends these features to the external model through “func()” defined in …..

NOTE: new member variables may be added to this structure in the future. Once new features are finalized, bump the major version of libaom.

Fields

id: AOM_EXT_PART_FEATURE_ID

Feature ID to indicate active features

before_part_none: aom_partition_features_before_none_t

Features collected before NONE partition

after_part_none: aom_partition_features_none_t

Features collected after NONE partition

after_part_split: aom_partition_features_split_t

Features collected after SPLIT partition

after_part_rect: aom_partition_features_rect_t

Features collected after RECTANGULAR partition

after_part_ab: aom_partition_features_ab_t

Features collected after AB partition

sb_features: aom_sb_features_t

Features collected for the super block

mi_row: c_int

Mi_row position of the block

mi_col: c_int

Mi_col position of the block

frame_width: c_int

Frame width

frame_height: c_int

Frame height

block_size: c_int

As “BLOCK_SIZE” in av1/common/enums.h

valid_partition_types: c_int

Valid partition types. A bitmask is used. “1” represents the corresponding type is valid. The bitmask follows the enum order for PARTITION_TYPE in “enums.h” to represent one partition type at a bit. For example, 0x01 stands for only PARTITION_NONE is valid, 0x09 (00…001001) stands for PARTITION_NONE and PARTITION_SPLIT are valid.

update_type: c_int

Frame update type, defined in ratectrl.h

qindex: c_int

Quantization index, range: [0, 255]

rdmult: c_int

Rate-distortion multiplier

pyramid_level: c_int

The level of this frame in the hierarchical structure

has_above_block: c_int

Has above neighbor block

above_block_width: c_int

Width of the above block, -1 if not exist

above_block_height: c_int

Height of the above block, -1 if not exist

has_left_block: c_int

Has left neighbor block

left_block_width: c_int

Width of the left block, -1 if not exist

left_block_height: c_int

Height of the left block, -1 if not exist

block_sse: c_uint

SSE of motion compensated residual

block_var: c_uint

Variance of motion compensated residual

sub_block_sse: [c_uint; 4]

SSE of sub blocks.

sub_block_var: [c_uint; 4]

Variance of sub blocks.

horz_block_sse: [c_uint; 2]

SSE of horz sub blocks

horz_block_var: [c_uint; 2]

Variance of horz sub blocks

vert_block_sse: [c_uint; 2]

SSE of vert sub blocks

vert_block_var: [c_uint; 2]

Variance of vert sub blocks

tpl_intra_cost: i64

Intra cost, ref to “TplDepStats” in tpl_model.h

tpl_inter_cost: i64

Inter cost in tpl model

tpl_mc_dep_cost: i64

Motion compensated dependency cost in tpl model
