Trait Implementations

impl AudioEncoder for OpusEncoder

fn encode( &mut self, frame: &AudioFrame, ) -> Result<Vec<EncodedAudioPacket>, AudioError>

Encode one input frame. The encoder buffers up to one output frame’s worth of samples internally — Opus’s smallest frame is 2.5 ms, default 20 ms — so this returns 0..N packets.

fn flush(&mut self) -> Result<Vec<EncodedAudioPacket>, AudioError>

Drain any buffered samples. May produce a final partial packet.

fn pre_skip(&self) -> u16

Lookahead samples at 48 kHz (Opus convention). For Opus, queried via OPUS_GET_LOOKAHEAD and scaled to 48 kHz when the encoder is internally running at a non-48k rate.

fn extra_data(&self) -> Vec<u8>

The codec-specific extra_data the muxer puts in the sample entry’s config box. For Opus this is the dOps body per RFC 7845 §4.5 (11 bytes for channel-mapping family 0).
