Enum SwAudioEncoderError 

pub enum SwAudioEncoderError {
    CodecNotFound(String),
    UnsupportedBuffer(&'static str),
    NoF32Format(String, Vec<Sample>),
    UnsupportedSampleRate(String, u32, Vec<u32>),
    Ffmpeg(Error),
}

Errors specific to SwAudioEncoder. Converts into the crate-wide Error via ? (see crate::error::Error).

Variants

CodecNotFound(String)

The requested encoder is unavailable in the linked FFmpeg build.

UnsupportedBuffer(&'static str)

The sink received a buffer other than decoded audio or end-of-stream.

NoF32Format(String, Vec<Sample>)

SwAudioEncoder only ever resamples to Sample::F32 (packed or planar, whichever the codec itself reports) — see its own docs on why. This is what a codec whose only supported formats are something else entirely (integer PCM, f64, …) gets instead of a silently-wrong guess. Neither codec this crate opens today (aac, libopus) hits this.

UnsupportedSampleRate(String, u32, Vec<u32>)

The codec publishes a fixed list of sample rates and SwAudioEncoderOptions::sample_rate is not on it — libopus takes only 48/24/16/12/8 kHz, for example. Caught here because avcodec_open2 reports it as a bare Invalid argument that names neither the rate nor the alternatives.

Ffmpeg(Error)

FFmpeg rejected encoder, resampler, frame, or packet processing.

Trait Implementations

impl Debug for SwAudioEncoderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SwAudioEncoderError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for SwAudioEncoderError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for SwAudioEncoderError

fn from(source: Error) -> Self

impl From<SwAudioEncoderError> for Error

fn from(source: SwAudioEncoderError) -> Self

Converts to this type from the input type.
