Struct OpusEncoder 

pub struct OpusEncoder {
    pub bitrate_bps: i32,
    pub complexity: i32,
    pub use_cbr: bool,

    pub packet_loss_perc: i32,
    /* private fields */
}

Fields

bitrate_bps: i32

complexity: i32

use_cbr: bool

use_inband_fec: bool

Enable in-band FEC (LBRR). When set to true, the encoder will include redundant copies of previous frames (at lower quality) to allow packet-loss recovery on the decoder side.

packet_loss_perc: i32

Expected packet loss percentage (0-100). Used to determine whether LBRR encoding is worth the overhead. Non-zero value enables LBRR when use_inband_fec is also true.

Implementations

impl OpusEncoder

pub fn new( sampling_rate: i32, channels: usize, application: Application, ) -> Result<Self, &'static str>

pub fn enable_hybrid_mode(&mut self) -> Result<(), &'static str>

Enable Hybrid mode (SILK + CELT). This is only valid for sampling rates of 24000 or 48000 Hz. In Hybrid mode, SILK handles the low-frequency portion and CELT handles the high-frequency. IMPORTANT: Hybrid mode requires the input to be at the encoder’s sampling rate (24kHz or 48kHz). The SILK encoder will internally use 16kHz for its processing.

pub fn encode( &mut self, input: &[f32], frame_size: usize, output: &mut [u8], ) -> Result<usize, &'static str>
