Wmv2DcPredBuffer

wmv_decoder::decoder

Struct Wmv2DcPredBuffer 

Source 
pub struct Wmv2DcPredBuffer { /* private fields */ }
Expand description

Predictor storage is in “scaled DC coefficient” domain (level * dc_scale). Default value 1024 corresponds to mid-gray (128) with scale=8.

Implementations§

Source§

impl Wmv2DcPredBuffer

Source

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

Source

pub fn predict( &self, mb_row: usize, mb_col: usize, blk: usize, scale: i32, ) -> (i32, i32)

Returns (pred_level, dir). dir=0 => left, dir=1 => top.

Source

pub fn store( &mut self, mb_row: usize, mb_col: usize, blk: usize, dc_coeff_scaled: i32, )
