Struct TrackGroup 

pub struct TrackGroup {
    pub owner_track_index: usize,
    pub owner_track_id: Option<String>,
    pub kind: TrackKind,
    pub partner_track_indices: Vec<usize>,
    pub partner_track_ids: Vec<Option<String>>,
}

One track group: an owner with its partners in slot order. A track in no group is reported as a group of one. Hosts use this to draw or collapse a group as one unit.

Fields

owner_track_index: usize

Index of the owner track (the video track of a video group, the main track of an audio group).

owner_track_id: Option<String>

Id of the owner track, when it has one.

kind: TrackKind

Kind of the owner: Video for a video group, Audio for an audio group.

partner_track_indices: Vec<usize>

Partner track indices in slot order (first partner right below the owner once normalized).

partner_track_ids: Vec<Option<String>>

Partner track ids in slot order.
