extract_adts_frames()

AacExtractResult extract_adts_frames

(

const std::vector< uint8_t > &

data

)

Extract AAC frames from a raw ADTS buffer.

extract_from_mp4()

std::optional< AacExtractResult > extract_from_mp4

(

const std::string &

path

)

Extract AAC frames and related tables from an MP4/M4A source.

Preferred when the input is already an MP4 container so we can reuse stsd/stts/stsc/stsz/stco and any meta/ilst payloads.
