Struct RefFrameMvs 

pub struct RefFrameMvs { /* private fields */ }

Reference frame motion vector storage.

Stores MVs for decoded reference frames to enable temporal prediction.

Implementations

impl RefFrameMvs

pub const fn new() -> Self

Creates new reference frame MV storage.

pub fn with_max_refs(self, max: usize) -> Self

Sets the maximum number of references.

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

Allocates storage for reference frames.

pub fn get_frame(&self, frame_idx: usize) -> Option<&MvCache>

Gets the MV cache for a reference frame.

pub fn get_frame_mut(&mut self, frame_idx: usize) -> Option<&mut MvCache>

Gets mutable MV cache for a reference frame.

pub fn store_frame(&mut self, frame_idx: usize, source: &MvCache)

Stores MVs from current frame as reference.

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

Gets co-located MV from reference frame.

pub fn shift_frames(&mut self)

Shifts reference frames (for new frame insertion).
