Struct BFrameReorderBuffer 

pub struct BFrameReorderBuffer { /* private fields */ }

B-frame reorder buffer.

Accepts frames in PTS order and emits ReadyFrames in decode order with computed DTS values.

Reorder algorithm (simplified)

Frames are collected into groups of pictures (GOPs). Within each GOP a run of B frames is deferred until its anchor P/I frame has been output. DTS is assigned as a monotonically increasing counter starting from the smallest PTS seen, offset back by max_b_frames * min_dts_delta to ensure DTS ≤ PTS for every frame.

Implementations

impl BFrameReorderBuffer

pub fn new(config: ReorderConfig) -> Self

Create a new reorder buffer with the given configuration.

pub fn default_config() -> Self

Create with default configuration.

pub fn push(&mut self, frame: QueuedFrame)

Push a frame in PTS / display order.

The buffer will internally decide when to emit frames in decode order.

pub fn flush(&mut self)

Flush all remaining frames (call at end of stream).

pub fn pop(&mut self) -> Option<ReadyFrame>

Pop the next ReadyFrame in decode order, or None if none are ready.

pub fn ready_len(&self) -> usize

Number of frames ready to be consumed.

pub fn pending_len(&self) -> usize

Number of frames still buffered (not yet emitted).

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

Formats the value using the given formatter.
