Struct OpusMSEncoder 

pub struct OpusMSEncoder {
    pub bitrate_bps: i32,
    /* private fields */
}

Multistream encoder: one Opus encoder per stream (coupled = stereo, the rest mono), coded per the channel layout and concatenated self-delimited.

Fields

bitrate_bps: i32

Total target bitrate across all streams (split evenly, coupled=2x mono).

Implementations

impl OpusMSEncoder

pub fn new( sample_rate: i32, channels: usize, mapping_family: i32, application: Application, ) -> Result<Self, Error>

A surround encoder for channels channels with the standard layout of mapping_family (see ChannelLayout::surround).

Errors

Error::BadArg for an unsupported channel count / mapping family, or any error from creating the per-stream encoders.

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

Split the total bitrate across streams (each coupled stream gets 2x a mono stream’s share, matching its 2 channels).

pub fn nb_streams(&self) -> usize

Number of Opus streams in each multistream packet.

pub fn encode( &mut self, input: &[f32], frame_size: usize, ) -> Result<Vec<u8>, Error>

Encode one frame of interleaved input (nb_channels per sample) into a multistream packet. scratch output is returned as a Vec.

Errors

Any error from the per-stream crate::OpusEncoder::encode calls or from assembling the self-delimited multistream packet.

pub fn sample_rate(&self) -> i32

Input sampling rate in Hz.

impl OpusMSEncoder

pub fn set_max_bandwidth(&mut self, bw: Bandwidth)

Cap the audio bandwidth of every stream at once.
