Struct AudioEncoder 

pub struct AudioEncoder { /* private fields */ }

Audio encoder.

Encodes audio frames to a file using FFmpeg.

Examples

use ff_encode::{AudioEncoder, AudioCodec};
use ff_format::{AudioFrame, SampleFormat};

let mut encoder = AudioEncoder::create("output.m4a")
    .expect("Failed to create encoder")
    .audio(48000, 2)
    .audio_codec(AudioCodec::Aac)
    .build_audio()
    .expect("Failed to build encoder");

// Create and push audio frames
let frame = AudioFrame::empty(1024, 2, 48000, SampleFormat::F32).unwrap();
encoder.push(&frame).expect("Failed to push frame");

encoder.finish().expect("Failed to finish encoding");

Implementations

impl AudioEncoder

pub fn create<P: AsRef<Path>>(path: P) -> Result<EncoderBuilder, EncodeError>

Create a new encoder builder with the given output path.

Arguments

• path - Output file path

Returns

Returns an EncoderBuilder for configuring the encoder.

Examples

use ff_encode::AudioEncoder;

let builder = AudioEncoder::create("output.m4a")?;

pub fn actual_codec(&self) -> &str

Get the actual audio codec being used.

Returns the name of the FFmpeg encoder (e.g., “aac”, “libopus”).

pub fn push(&mut self, frame: &AudioFrame) -> Result<(), EncodeError>

Push an audio frame for encoding.

Arguments

• frame - The audio frame to encode

Errors

Returns an error if encoding fails or the encoder is not initialized.

Examples

use ff_encode::{AudioEncoder, AudioCodec};
use ff_format::{AudioFrame, SampleFormat};

let mut encoder = AudioEncoder::create("output.m4a")?
    .audio(48000, 2)
    .audio_codec(AudioCodec::Aac)
    .build()?;

let frame = AudioFrame::empty(1024, 2, 48000, SampleFormat::F32)?;
encoder.push(&frame)?;

pub fn finish(self) -> Result<(), EncodeError>

Finish encoding and write the file trailer.

This method must be called to properly finalize the output file. It flushes any remaining encoded frames and writes the file trailer.

Errors

Returns an error if finalizing fails.

Trait Implementations

impl Drop for AudioEncoder

fn drop(&mut self)

Executes the destructor for this type.
