Struct RefFrame 

pub struct RefFrame {
    pub poc: i32,
    pub frame_num: u32,
    pub ref_type: RefFrameType,
    pub in_use: bool,
    pub buffer_index: usize,
}

A reference frame entry in the decoded picture buffer.

Fields

poc: i32

Picture order count (POC).

frame_num: u32

frame_num for short-term or long-term frame index for long-term.

ref_type: RefFrameType

Reference type.

in_use: bool

true when this entry is actually in use (not an empty slot).

buffer_index: usize

Opaque frame data buffer index (into a larger buffer pool).

Implementations

impl RefFrame

pub fn short_term(poc: i32, frame_num: u32, buffer_index: usize) -> Self

Creates a new short-term reference frame.

pub fn long_term( poc: i32, long_term_frame_idx: u32, buffer_index: usize, ) -> Self

Creates a new long-term reference frame.

pub fn is_valid(&self) -> bool

Returns true when this slot is occupied by a valid reference frame.

pub fn mark_unused(&mut self)

Marks this frame as unused (removes it from the DPB logically).

Trait Implementations

impl Clone for RefFrame

fn clone(&self) -> RefFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RefFrame

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
