Struct AudioOnlyTranscoder 

pub struct AudioOnlyTranscoder { /* private fields */ }

Audio-only transcoder.

Accepts raw PCM samples (f32, -1.0..=1.0), applies channel mapping and level adjustments, and returns the processed output samples.

In a full pipeline this struct would wrap actual codec encode/decode calls; here it provides the configuration layer and frame-level processing hooks that the codec pipeline can call.

Implementations

impl AudioOnlyTranscoder

pub fn new(config: AudioOnlyConfig) -> Self

Creates a new AudioOnlyTranscoder from a validated config.

pub fn config(&self) -> &AudioOnlyConfig

Returns the active configuration.

pub fn codec_name(&self) -> &str

Returns the output codec name string.

pub fn estimated_bitrate(&self) -> u32

Returns the effective output bitrate in bits per second.

If config.bitrate is 0 the codec default is returned.

pub fn frames_processed(&self) -> u64

Number of audio frames processed since creation (or last reset).

pub fn transcode_samples(&mut self, input: &[f32]) -> Result<Vec<f32>>

Process a block of interleaved PCM samples.

Input samples must be interleaved with the number of channels declared in the config, in f32 format. Output length equals input length after channel mapping (no sample-rate conversion is performed in this stub – that would be delegated to oximedia-audio::resample).

Errors

Returns TranscodeError::InvalidInput when:

• input length is not a multiple of channels
• any individual sample is NaN or infinite

pub fn reset(&mut self)

Reset internal counters (e.g. between programs).

pub fn update_config( &mut self, input_codec: AudioCodecId, output_codec: AudioCodecId, sample_rate: u32, channels: u8, bitrate: u32, ) -> Result<()>

Update the config on the fly (e.g. for adaptive bitrate pipelines).

Errors

Returns an error if the new config fails validation.
