Struct ProjectionDecoder 

pub struct ProjectionDecoder { /* private fields */ }

Safe wrapper around OpusProjectionDecoder.

Implementations

impl ProjectionDecoder

pub fn new( sample_rate: SampleRate, channels: u8, streams: u8, coupled_streams: u8, demixing_matrix: &[u8], ) -> Result<Self>

Create a projection decoder given the demixing matrix provided by the encoder.

Errors

Returns Error::BadArg for invalid inputs, Error::from_code for libopus failures, or Error::AllocFail if libopus returns a null handle.

pub fn decode( &mut self, packet: &[u8], out: &mut [i16], frame_size_per_ch: usize, fec: bool, ) -> Result<usize>

Decode into interleaved i16 PCM.

Errors

Returns Error::InvalidState if the decoder handle was freed, Error::BadArg for buffer/layout issues, a mapped libopus error, or Error::InternalError if libopus reports an impossible decoded sample count.

pub fn decode_float( &mut self, packet: &[u8], out: &mut [f32], frame_size_per_ch: usize, fec: bool, ) -> Result<usize>

Decode into interleaved f32 PCM.

Errors

Returns Error::InvalidState if the decoder handle was freed, Error::BadArg for buffer/layout issues, a mapped libopus error, or Error::InternalError if libopus reports an impossible decoded sample count.

pub const fn channels(&self) -> u8

Output channel count.

pub const fn streams(&self) -> u8

Number of coded streams expected in the input bitstream.

pub const fn coupled_streams(&self) -> u8

Number of coupled coded streams expected in the input bitstream.

pub const fn sample_rate(&self) -> SampleRate

Decoder sample rate.
