Struct ReferenceFrameBuffer 

pub struct ReferenceFrameBuffer { /* private fields */ }

Simple reference frame buffer for P-slice decoding.

Maintains a bounded FIFO of recent reconstructed frames so that P-slices can reference them for motion compensation.

Implementations

impl ReferenceFrameBuffer

pub fn new(max_refs: usize) -> Self

Creates a new buffer that keeps at most max_refs reference frames.

pub fn push(&mut self, frame: Vec<u8>)

Pushes a reconstructed frame into the buffer, evicting the oldest if the capacity is exceeded.

pub fn get(&self, idx: usize) -> Option<&[u8]>

Returns the reference frame at idx (0 = oldest retained frame).

pub fn latest(&self) -> Option<&[u8]>

Returns the most recently pushed reference frame.

pub fn len(&self) -> usize

Returns the number of reference frames currently stored.

pub fn is_empty(&self) -> bool

Returns true if the buffer contains no reference frames.
