Crate opusenc 

High-level bindings for libopusenc.

Example

let audio_data: Vec<i16> = {
    let mut file = std::fs::File::open("/dev/urandom")?;
    let mut buf = vec![0; 60 * 48_000 * 2 * 2];
    file.read_exact(&mut buf)?;
    buf.chunks_exact(2)
        .map(|a| i16::from_ne_bytes([a[0], a[1]]))
        .collect()
};

let mut encoder = Encoder::create_file(
    "/tmp/noise.opus",
    Comments::create()
        .add(RecommendedTag::Title, "Random Noise")?
        .add(RecommendedTag::Artist, "/dev/urandom")?,
    48_000,
    2,
    MappingFamily::MonoStereo,
)?;
     
encoder.write(&audio_data)?;
encoder.drain()?;

Encoder options

This crate provides a encoder-options feature which enables reading and changing encoder options.

Warning: Some of these options might not work with opusenc, may be unsafe or even cause UB. They are intended to be used via C macros that don’t work with Rust. Make sure to check if the methods you use match their intended behaviour.
