Struct VideoAnimationDecoder 

pub struct VideoAnimationDecoder<D, C, R> { /* private fields */ }

A composited-canvas animation view over a demuxed, decoded video: the first video track, in presentation order.

Implementations

impl<D: Demuxer, C: VideoDecoder, R: RenderFrame> VideoAnimationDecoder<D, C, R>

pub fn new( bytes: Arc<[u8]>, dem: D, dec: C, render: R, final_duration: FrameDuration, window: usize, ) -> Self

Decode bytes with dem and dec, rendering through render. final_duration is how long the last frame lasts: a video stream has none for its last presentation unless the container records one. window is the slice driver’s read size (bytes per step).

pub fn frames_decoded(&self) -> u64

Frames the video decoder produced so far (some may still be queued for duration lookahead).

pub fn demuxer(&self) -> &D

The demuxer.

Trait Implementations

impl<D, C, R> AnimationFrameDecoder for VideoAnimationDecoder<D, C, R>

where D: Demuxer + Send, C: VideoDecoder + Send, R: RenderFrame + Send,

type Error = AdaptError<<D as Demuxer>::Error, <C as VideoDecoder>::Error>

The codec-specific error type.

fn wrap_sink_error(err: SinkError) -> Self::Error

Wrap a SinkError into this decoder’s error type.

fn info(&self) -> &ImageInfo

Image metadata, available after construction.

fn render_next_frame( &mut self, pulse: Option<&dyn Pulse>, ) -> Result<Option<AnimationFrame<'_>>, Self::Error>

Render the next composited full-canvas frame.

fn render_next_frame_to_sink( &mut self, pulse: Option<&dyn Pulse>, sink: &mut dyn DecodeRowSink, ) -> Result<Option<OutputInfo>, Self::Error>

Render the next frame directly into a caller-owned sink (push model).

fn frame_count(&self) -> Option<u32>

Number of frames, if known without decoding.

fn loop_count(&self) -> Option<u32>

Animation loop count from the container.

fn render_next_frame_owned( &mut self, pulse: Option<&dyn Pulse>, ) -> Result<Option<OwnedAnimationFrame>, Self::Error>

Render the next frame as an owned copy.
