Struct PacketReorderer 

pub struct PacketReorderer { /* private fields */ }

Reorders DTS-ordered packets (as produced by encoders with B-frames) into PTS order (required by muxers and decoders operating on display order).

Internally uses a min-heap keyed on PTS. A packet is considered ready once the heap has accumulated at least max_buffer entries, which bounds the maximum PTS reordering delay.

Flushing

Call drain at end-of-stream to retrieve all remaining packets in PTS order.

Implementations

impl PacketReorderer

pub fn new(max_buffer: usize) -> Self

Create a new reorderer.

max_buffer controls the maximum reorder window. A value of 4–8 is appropriate for streams with up to 3 consecutive B-frames.

pub fn push(&mut self, pkt: CodecPacket)

Push a packet into the reorder buffer.

pub fn pop_ready(&mut self) -> Option<CodecPacket>

Pop the packet with the lowest PTS if the buffer is full enough to guarantee it is the next in display order.

Returns None if the buffer is smaller than max_buffer.

pub fn drain(&mut self) -> Vec<CodecPacket>

Drain all remaining packets from the buffer, ordered by PTS ascending.

The buffer is empty after this call.

pub fn len(&self) -> usize

Number of packets currently buffered.

pub fn is_empty(&self) -> bool

Returns true if the buffer contains no packets.
