Struct CarrierVideoStreamDecoder 

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

mediadecode::VideoStreamDecoder impl with transparent HW → SW fallback.

Implementations

impl CarrierVideoStreamDecoder<View>

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

Opens a video decoder for parameters, probing hardware backends in order and falling back to software.

pub const fn is_software(&self) -> bool

Whether this decoder is currently running on software.

pub const fn is_hardware(&self) -> bool

Whether this decoder is currently running on hardware.

pub fn hardware_inner(&self) -> Option<&VideoDecoder>

The hardware wrapper, when one is in use.

pub const fn time_base(&self) -> Timebase

The stream timebase every produced timestamp is stamped with.

impl CarrierVideoStreamDecoder<Owned>

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

Opens a video decoder for parameters, probing hardware backends in order and falling back to software.

pub const fn is_software(&self) -> bool

Whether this decoder is currently running on software.

pub const fn is_hardware(&self) -> bool

Whether this decoder is currently running on hardware.

pub fn hardware_inner(&self) -> Option<&VideoDecoder>

The hardware wrapper, when one is in use.

pub const fn time_base(&self) -> Timebase

The stream timebase every produced timestamp is stamped with.

Trait Implementations

impl VideoStreamDecoder for CarrierVideoStreamDecoder<View>

type Adapter = Ffmpeg

Backend-specific vocabulary.

type Buffer = <View as FfmpegCarrier>::Buffer

Buffer type held by the packets and frames this decoder produces or accepts.

type Error = VideoDecodeError

Decoder-specific error type.

fn send_packet( &mut self, packet: &VideoPacket<VideoPacketExtra, Self::Buffer>, ) -> Result<(), Self::Error>

Submits one compressed packet.

fn receive_frame( &mut self, dst: &mut VideoFrame<PixelFormat, VideoFrameExtra, Self::Buffer>, ) -> Result<(), Self::Error>

Drains one decoded frame into dst. Backends signal “no frame ready” via a backend-specific Error variant.

fn send_eof(&mut self) -> Result<(), Self::Error>

Signals end-of-stream.

fn flush(&mut self) -> Result<(), Self::Error>

Flushes internal state.

impl VideoStreamDecoder for CarrierVideoStreamDecoder<Owned>

type Adapter = Ffmpeg

Backend-specific vocabulary.

type Buffer = <Owned as FfmpegCarrier>::Buffer

Buffer type held by the packets and frames this decoder produces or accepts.

type Error = VideoDecodeError

Decoder-specific error type.

fn send_packet( &mut self, packet: &VideoPacket<VideoPacketExtra, Self::Buffer>, ) -> Result<(), Self::Error>

Submits one compressed packet.

fn receive_frame( &mut self, dst: &mut VideoFrame<PixelFormat, VideoFrameExtra, Self::Buffer>, ) -> Result<(), Self::Error>

Drains one decoded frame into dst. Backends signal “no frame ready” via a backend-specific Error variant.
