Struct AudioVariantSpec 

pub struct AudioVariantSpec {
    pub codec_string: String,
    pub channels: u16,
    pub sample_rate: u32,
    pub relative_dir: String,
    pub language: String,
    pub name: String,
    pub manifest: CmafTrackManifest,
}

Description of one audio rendition. CMAF-HLS uses a separate rendition group so video variants can switch bitrate without touching the audio track. We currently emit exactly one audio rendition (default English / undetermined-language); multi-track audio is a future task.

Fields

codec_string: String

Codec string for the audio track — typically AAC_LC_CODEC_STRING (mp4a.40.2).

channels: u16

Channel count. Goes in CHANNELS="<n>" per RFC 8216 §4.3.4.2.

sample_rate: u32

Sample rate in Hz. Informational; not surfaced in the playlist directly but kept on the spec so the validator can verify the init segment matches.

relative_dir: String

Relative directory under the asset root, e.g. "audio".

language: String

BCP-47 language tag — "en", "es", "und" for undetermined.

name: String

Human-readable rendition name. Players use this in their UI.

manifest: CmafTrackManifest
