The TrackDefault() constructor of the TrackDefault interface constructs and returns a new TrackDefault object.

Syntax

var trackDefault = new TrackDefault(type, language, label, kinds, byteStreamTrackID);

Parameters

type: A DOMString specifying a media segment data type for the SourceBuffer to contain. Can be audio, video, or text.
language: A DOMString specifying a default language for the SourceBuffer to use when an initialization segment does not contain language information for a new track.
label: A DOMString specifying a default label for the SourceBuffer to use when an initialization segment does not contain label information for a new track.
kinds: An array (sequence) of DOMStrings specifying default kinds for the SourceBuffer to use when an initialization segment does not contain kind information for a new track.
byteStreamTrackID Optional: A DOMString specifying the ID of the specific track that the SourceBuffer should apply to. If not specified, this value will be an empty string and the SourceBuffer can contain any tracks of the specified type.
