Struct Ac4Decoder 

pub struct Ac4Decoder {
    pub last_info: Option<Ac4FrameInfo>,
    pub last_substream: Option<Ac4SubstreamInfo>,
    /* private fields */
}

Fields

last_info: Option<Ac4FrameInfo>

Last parsed frame info — exposed for downstream inspection.

last_substream: Option<Ac4SubstreamInfo>

Last parsed substream tool summary (first substream of the last decoded frame). None when the TOC didn’t expose a usable size for the substream (e.g. single-substream frame where b_size_present == 0).

Trait Implementations

impl Decoder for Ac4Decoder

fn codec_id(&self) -> &CodecId

fn send_packet(&mut self, packet: &Packet) -> Result<()>

Feed one compressed packet. May or may not produce a frame immediately — call receive_frame in a loop afterwards.

fn receive_frame(&mut self) -> Result<Frame>

Pull the next decoded frame, if any. Returns Error::NeedMore when the decoder needs another packet.

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

Signal end-of-stream. After this, receive_frame will drain buffered frames and eventually return Error::Eof.

fn receive_arena_frame(&mut self) -> Result<Arc<FrameInner>, Error>

Pull the next decoded frame as an arena-backed arena::sync::Frame.

fn reset(&mut self) -> Result<(), Error>

Discard all carry-over state so the decoder can resume from a new bitstream position without producing stale output. Called by the player after a container seek.

fn set_execution_context(&mut self, _ctx: &ExecutionContext)

Advisory: announce the runtime environment (today: a thread budget for codec-internal parallelism). Called at most once, before the first send_packet. Default no-op; codecs that want to run slice-/GOP-/tile-parallel override this to capture the budget. Ignoring the hint is always safe — callers must still work with a decoder that runs serial.
