Struct CarrierImageDecoder 

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

mediadecode::ImageDecoder impl wrapping ffmpeg::decoder::Video.

Opened from the codec parameters of an Attachment track — see the module docs for the whole road.

Implementations

impl CarrierImageDecoder<View>

pub fn open( parameters: Parameters, limits: DecoderLimits, ) -> Result<Self, ImageDecodeError>

Opens a still-image decoder for parameters.

pub const fn limits(&self) -> DecoderLimits

The budgets this decoder was opened with.

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

The wrapped decoder context.

impl CarrierImageDecoder<Owned>

pub fn open( parameters: Parameters, limits: DecoderLimits, ) -> Result<Self, ImageDecodeError>

Opens a still-image decoder for parameters.

pub const fn limits(&self) -> DecoderLimits

The budgets this decoder was opened with.

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

The wrapped decoder context.

Trait Implementations

impl ImageDecoder for CarrierImageDecoder<View>

type Adapter = Ffmpeg

Backend-specific vocabulary.

type Buffer = <View as FfmpegCarrier>::Buffer

Buffer type held by the packet this decoder accepts and the frame it produces. See the module docs for what may be bound here.

type Error = ImageDecodeError

Decoder-specific error type.

fn decode( &mut self, packet: &AttachmentPacket<AttachmentPacketExtra, Self::Buffer>, ) -> Result<ImageFrame<PixelFormat, ImageFrameExtra, Self::Buffer>, Self::Error>

Decodes one attachment payload — a whole image file — into a still.

impl ImageDecoder for CarrierImageDecoder<Owned>

type Adapter = Ffmpeg

Backend-specific vocabulary.

type Buffer = <Owned as FfmpegCarrier>::Buffer

Buffer type held by the packet this decoder accepts and the frame it produces. See the module docs for what may be bound here.

type Error = ImageDecodeError

Decoder-specific error type.

fn decode( &mut self, packet: &AttachmentPacket<AttachmentPacketExtra, Self::Buffer>, ) -> Result<ImageFrame<PixelFormat, ImageFrameExtra, Self::Buffer>, Self::Error>

Decodes one attachment payload — a whole image file — into a still.
