Enum TrackParams 

pub enum TrackParams<E: DemuxAdapter> {
    Video(VideoTrackParams<E>),
    Audio(AudioTrackParams<E>),
    Subtitle(SubtitleTrackParams<E>),
    Data(DataTrackParams<E>),
    Attachment(AttachmentTrackParams<E>),
    Unknown(UnknownTrackParams<E>),
}

A track’s codec and per-kind parameters.

The arm is the kind: TrackInfo::kind reads it off this enum rather than storing a second copy that could disagree with the payload beside it.

No Clone — see TrackInfo’s own doc for the message-carrier law that keeps it off this type too.

Variants

Video(VideoTrackParams<E>)

Motion video.

Audio(AudioTrackParams<E>)

Audio.

Subtitle(SubtitleTrackParams<E>)

Subtitles / captions.

Data(DataTrackParams<E>)

Timed opaque data.

Attachment(AttachmentTrackParams<E>)

An attached file — a font, cover art.

Unknown(UnknownTrackParams<E>)

A track the backend could not classify.
