Stats from decode_baseline_idr_slice. A superset of SliceWalkStats for testability — coding_units, residual coeff counts, etc.

Fields

ctus: u32

split_cu_flag_bins: u32

coding_units: u32

cbf_luma_bins: u32

cbf_chroma_bins: u32

intra_pred_mode_bins: u32

ibc_flag_bins: u32

ibc_flag regular bins decoded per §7.3.8.4 line 2845 (gated on the round-90 isIbcAllowed predicate). One per IBC-eligible CU.

ibc_cus: u32

Coding units that resolved CuPredMode == MODE_IBC after ibc_flag = 1 and were reconstructed via decode_ibc_cu.

ibc_abs_mvd_bins: u32

abs_mvd_l0[0/1] EG-0 bypass invocations consumed by the IBC coding_unit() branch (two per IBC CU).

ibc_mvd_sign_bins: u32

mvd_l0_sign_flag bypass bits consumed by the IBC coding_unit() branch (one per non-zero abs_mvd component).

cu_qp_delta_abs_bins: u32

cu_qp_delta_abs U-binarized syntax elements decoded inside the IDR-path transform_unit() (§7.3.8.5 line 3073-3078). One increment per CU (intra or IBC) that satisfies the presence condition cu_qp_delta_enabled_flag && (cbf_luma || cbf_cb || cbf_cr).

coeff_runs: u32

deblock_edges: u32

Deblocking edges visited (zero when slice_deblocking_filter_flag = 0).

alf_ctb: AlfCtbStats

Per-CTU alf_ctb_* map bins from coding_tree_unit() (§7.3.8.2). Zero unless the slice signals an ALF applicability map.

alf_ctb_map: AlfCtbMap

Round 113: the resolved per-CTU alf_ctb_* applicability map (§7.3.8.2 → §8.9). Carries one triplet per CTU so the post-filter pass can mask the ALF apply per coding tree block. Always populated (sized to the picture); every entry is the present-or-inferred on/off state for that CTU.

Trait Implementations

impl Clone for SliceDecodeStats

fn clone(&self) -> SliceDecodeStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SliceDecodeStats

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SliceDecodeStats

fn default() -> SliceDecodeStats

Returns the “default value” for a type.

impl Eq for SliceDecodeStats

impl PartialEq for SliceDecodeStats

fn eq(&self, other: &SliceDecodeStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
