Struct MvCache 

pub struct MvCache { /* private fields */ }

Motion vector cache for a frame.

Stores motion vectors in a grid aligned to 4x4 blocks (MI units).

Implementations

impl MvCache

pub const fn new() -> Self

Creates a new empty cache.

pub fn allocate(&mut self, width: usize, height: usize, num_refs: usize)

Allocates cache for a frame.

pub fn clear(&mut self)

Clears all entries.

pub const fn mi_cols(&self) -> usize

Returns the width in MI units.

pub const fn mi_rows(&self) -> usize

Returns the height in MI units.

pub fn get( &self, mi_row: usize, mi_col: usize, ref_idx: usize, ) -> Option<&MvCacheEntry>

Gets an entry.

pub fn get_mut( &mut self, mi_row: usize, mi_col: usize, ref_idx: usize, ) -> Option<&mut MvCacheEntry>

Gets a mutable entry.

pub fn set( &mut self, mi_row: usize, mi_col: usize, ref_idx: usize, entry: MvCacheEntry, )

Sets an entry.

pub fn fill_block( &mut self, mi_row: usize, mi_col: usize, block_size: BlockSize, ref_idx: usize, entry: MvCacheEntry, )

Fills a block region with an entry.

pub fn get_left( &self, mi_row: usize, mi_col: usize, ref_idx: usize, ) -> Option<&MvCacheEntry>

Gets the left neighbor entry.

pub fn get_top( &self, mi_row: usize, mi_col: usize, ref_idx: usize, ) -> Option<&MvCacheEntry>

Gets the top neighbor entry.

pub fn get_top_right( &self, mi_row: usize, mi_col: usize, block_size: BlockSize, ref_idx: usize, ) -> Option<&MvCacheEntry>

Gets the top-right neighbor entry.

pub fn get_top_left( &self, mi_row: usize, mi_col: usize, ref_idx: usize, ) -> Option<&MvCacheEntry>

Gets the top-left neighbor entry.
