Struct OpusEncoder 

pub struct OpusEncoder { /* private fields */ }

Implementations

impl OpusEncoder

pub fn new_with_application( sample_rate: u32, channels: u16, application: Application, ) -> Self

pub fn new(sample_rate: u32, channels: u16) -> Self

Create a new Opus encoder instance.

Keep backward-compatible defaults with pre-0.3.31 behavior:

• VoIP application
• caller can provide mono PCM even when encoder is configured as stereo; encode() duplicates mono samples to stereo.

pub fn new_default() -> Self

Create a default Opus encoder (48kHz, stereo)

pub fn set_bitrate(&mut self, bitrate_bps: i32)

Set the encoder bitrate in bits per second.

pub fn set_complexity(&mut self, complexity: i32)

Set the encoder complexity (0-10).

pub fn set_cbr(&mut self, cbr: bool)

Enable or disable constant bitrate (CBR) mode.

pub fn encode_into_raw( &mut self, samples: &[Sample], output: &mut [u8], ) -> Option<usize>

Encode into a caller-provided packet buffer.

Returns Some(bytes_written) on success. Expects samples to match the encoder’s channel count (interleaved stereo when channels == 2).

Trait Implementations

impl Encoder for OpusEncoder

fn encode(&mut self, samples: &[Sample]) -> Vec<u8>

Override the default to preserve back-comat mono→stereo upmix when the encoder was configured with channels == 2.

fn encode_into( &mut self, samples: &[Sample], out: &mut [u8], ) -> Result<usize, CodecError>

Encode samples into out, returning the number of bytes written.

fn max_encode_bytes(&self, _n_samples: usize) -> usize

Upper bound on the number of bytes that encode_into will write for an input of n_samples samples.

fn sample_rate(&self) -> u32

Get the sample rate expected for input samples.

fn channels(&self) -> u16

Get the number of channels expected for input.
