Struct AcPredBuffer 

pub struct AcPredBuffer { /* private fields */ }

Implementations

impl AcPredBuffer

pub fn new(mb_w: usize, mb_h: usize) -> Self

pub fn clear(&mut self)

pub fn pred_row(&self, mb_row: usize, mb_col: usize, blk: usize) -> [i32; 7]

Get the AC predictor row (indices 1..7 of the reconstructed block). Returns the first row of the left neighbour (for horizontal prediction).

pub fn pred_col(&self, mb_row: usize, mb_col: usize, blk: usize) -> [i32; 7]

Get the AC predictor column (rows 1..7 of the reconstructed block). Returns the first column of the top neighbour (for vertical prediction).

pub fn pred_left_col( &self, mb_row: usize, mb_col: usize, blk: usize, ) -> [i32; 7]

VC-1 AC prediction from the left uses the neighbour’s first coefficient column.

pub fn pred_top_row(&self, mb_row: usize, mb_col: usize, blk: usize) -> [i32; 7]

VC-1 AC prediction from the top uses the neighbour’s first coefficient row.

pub fn store_row( &mut self, mb_row: usize, mb_col: usize, blk: usize, row: [i32; 7], )

pub fn store_col( &mut self, mb_row: usize, mb_col: usize, blk: usize, col: [i32; 7], )

Trait Implementations

impl Clone for AcPredBuffer

fn clone(&self) -> AcPredBuffer

Returns a duplicate of the value.

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

Performs copy-assignment from source.
