Struct AudioTrack 

pub struct AudioTrack {
    pub codec: String,
    pub samples: Vec<Vec<u8>>,
    pub sample_rate: u32,
    pub channels: u16,
    pub asc: Vec<u8>,
    pub codec_private: Vec<u8>,
    pub timescale: u32,
    pub durations: Vec<u32>,
}

Audio track extracted for passthrough or transcode. Supports two codec families today (Squad-18 + Squad-23):

• AAC-LC: codec = "aac", asc holds the verbatim AudioSpecificConfig bytes sourced from the MP4 esds descriptor (not the mp4 crate’s rebuilt form) or MKV CodecPrivate, so HE-AAC / xHE-AAC signaling survives the copy. codec_private is empty.
• Opus: codec = "opus", codec_private holds the RFC 7845 §5.1 OpusHead body verbatim — for MKV/WebM that’s exactly the CodecPrivate element bytes (post-magic — RFC 7845 §5.2 specifies no magic prefix for the MKV CodecPrivate); for MP4-Opus that’s the dOps body re-serialised in OpusHead’s LE numeric convention. asc is empty.

samples are codec-native packets (AAC: ADTS-stripped raw access units; Opus: TOC-prefixed Opus packets, one per frame). durations are per-sample in timescale units.

Fields

codec: String

samples: Vec<Vec<u8>>

sample_rate: u32

channels: u16

asc: Vec<u8>

AAC-only: AudioSpecificConfig bytes. Empty for non-AAC codecs.

codec_private: Vec<u8>

Opus-only: OpusHead body bytes (RFC 7845 §5.1). Empty for non-Opus codecs. The 8-byte ‘OpusHead’ magic prefix is NOT included — only the post-magic body.

timescale: u32

durations: Vec<u32>
