Struct Cea708CueExtractor 

pub struct Cea708CueExtractor { /* private fields */ }

Available on crate feature cc-data only.

Extracts Cues from a single CEA-708 (DTVCC) service (CTA-708-E), wrapping a cc-data cc_data::decode::Cea708Decoder.

Reads cc_data::decode::Cea708Decoder::service_text for the configured service number (1-6; service 1 is the primary caption service) after each fed frame — see crate::webvtt module docs for the diff-based boundary design and its documented losses (styling, window geometry, cross-service merging).

Implementations

impl Cea708CueExtractor

pub fn new(service_number: usize) -> Self

A new extractor tracking the given CEA-708 service number (1-6).

pub fn push_frame(&mut self, pts33: u64, triplets: &[CcTriplet])

Feed one access unit’s CEA-708 triplets (already demuxed from its cc_data()), tagged with that access unit’s raw 33-bit PTS. Non-708 triplets in triplets are ignored.

pub fn finalize(&mut self, end_pts33: u64)

Close any still-open cue at end of stream, at end_pts33.

pub fn cues(&self) -> &[Cue]

The cues extracted so far, in order.

pub fn into_cues(self) -> Vec<Cue>

Consume the extractor, returning the extracted cues.
