Struct ToyEncoder 

pub struct ToyEncoder { /* private fields */ }

Toy encoder: one gray picture per packet, lookahead frames held back, a random-access point every keyint packets.

Implementations

impl ToyEncoder

pub fn new( width: u32, height: u32, time_base: TimeBase, lookahead: usize, keyint: u64, ) -> Self

An encoder of width x height grey pictures on time_base, holding lookahead frames and marking every keyint-th packet as a random-access point.

pub fn lookahead(&self) -> usize

Frames held before their packet comes out.

Trait Implementations

impl VideoEncoder for ToyEncoder

type Error = ToyError

The implementation’s error.

fn send( &mut self, frame: &Frame, stop: Option<&dyn Pulse>, ) -> Result<SendStatus, SessionError<ToyError>>

Offer a frame handle. The encoder clones it to queue (no pixel copy is required by the contract; a backend may copy into padded planes).

fn receive( &mut self, stop: Option<&dyn Pulse>, ) -> Result<Receive<Packet>, SessionError<ToyError>>

One packet at a time, in decode order, carrying the presentation timestamp of the frame it shows.

fn end_input(&mut self) -> Result<(), SessionError<ToyError>>

Declare end of input; idempotent. Then receive until EndOfStream.

fn output_config(&self) -> Option<&CodecConfig>

Codec configuration a muxer needs before the first packet.

fn output_fidelity(&self) -> Option<Fidelity>

Fidelity guaranteed by this actual prepared encoder for every accepted input frame. None means unqualified, not lossy or lossless. A guarantee must not be inferred from codec identity or an unvalidated request. This describes encoding only; preceding conversion may lose samples. Fixed-configuration operations bind this value with output_config and reject a later change before publishing staged output.
