Struct CarrierResampler 

pub struct CarrierResampler<C: FfmpegCarrier> { /* private fields */ }

Available on crate feature resample only.

mediadecode::resampler::AudioResampler impl wrapping swresample.

Construction is Self::new, off the trait, taking both specs — see the trait’s own documentation for why the target can never be a constant.

Implementations

impl CarrierResampler<View>

pub fn new( source: ResampleSpec, target: ResampleSpec, limits: FrameLimits, ) -> Result<Self, ResampleError>

Opens a resampler between two explicit specs. See CarrierResampler::new_impl for the full contract.

pub const fn source(&self) -> &ResampleSpec

The spec frames must arrive in.

pub const fn target(&self) -> &ResampleSpec

The spec frames leave in.

pub const fn inner(&self) -> &Context

The wrapped swr context.

pub fn delay(&self) -> i64

Samples still inside the delay line, counted at the output rate.

impl CarrierResampler<Owned>

pub fn new( source: ResampleSpec, target: ResampleSpec, limits: FrameLimits, ) -> Result<Self, ResampleError>

Opens a resampler between two explicit specs. See CarrierResampler::new_impl for the full contract.

pub const fn source(&self) -> &ResampleSpec

The spec frames must arrive in.

pub const fn target(&self) -> &ResampleSpec

The spec frames leave in.

pub const fn inner(&self) -> &Context

The wrapped swr context.

pub fn delay(&self) -> i64

Samples still inside the delay line, counted at the output rate.

Trait Implementations

impl AudioResampler for CarrierResampler<View>

type Adapter = Ffmpeg

Backend vocabulary. The source and target specs are both expressed in it.

type Buffer = <View as FfmpegCarrier>::Buffer

Buffer type held by the frames this resampler accepts and produces.

type Error = ResampleError

Resampler-specific error type. Carries both the “nothing ready yet” signal out of receive_frame and the mid-stream-change refusal out of send_frame.

fn send_frame( &mut self, frame: &AudioFrame<SampleFormat, ChannelLayoutDescription, AudioFrameExtra, <View as FfmpegCarrier>::Buffer>, ) -> Result<(), ResampleError>

Submits one decoded frame.

fn receive_frame( &mut self, dst: &mut AudioFrame<SampleFormat, ChannelLayoutDescription, AudioFrameExtra, <View as FfmpegCarrier>::Buffer>, ) -> Result<(), ResampleError>

Drains one converted frame into dst. Implementations signal “no frame ready” via a backend-specific Error variant, exactly as AudioStreamDecoder::receive_frame does.

fn send_eof(&mut self) -> Result<(), ResampleError>

Signals end of stream. The conversion tail becomes drainable through receive_frame.

fn flush(&mut self) -> Result<(), ResampleError>

Flushes internal state — buffered input, the undrained tail, and the output timestamp anchor — leaving the resampler ready for a fresh stream on the same two specs.

impl AudioResampler for CarrierResampler<Owned>

type Adapter = Ffmpeg

Backend vocabulary. The source and target specs are both expressed in it.

type Buffer = <Owned as FfmpegCarrier>::Buffer

Buffer type held by the frames this resampler accepts and produces.

type Error = ResampleError

Resampler-specific error type. Carries both the “nothing ready yet” signal out of receive_frame and the mid-stream-change refusal out of send_frame.

fn send_frame( &mut self, frame: &AudioFrame<SampleFormat, ChannelLayoutDescription, AudioFrameExtra, <Owned as FfmpegCarrier>::Buffer>, ) -> Result<(), ResampleError>

Submits one decoded frame.

fn receive_frame( &mut self, dst: &mut AudioFrame<SampleFormat, ChannelLayoutDescription, AudioFrameExtra, <Owned as FfmpegCarrier>::Buffer>, ) -> Result<(), ResampleError>

Drains one converted frame into dst. Implementations signal “no frame ready” via a backend-specific Error variant, exactly as AudioStreamDecoder::receive_frame does.

fn send_eof(&mut self) -> Result<(), ResampleError>

Signals end of stream. The conversion tail becomes drainable through receive_frame.

fn flush(&mut self) -> Result<(), ResampleError>

Flushes internal state — buffered input, the undrained tail, and the output timestamp anchor — leaving the resampler ready for a fresh stream on the same two specs.
