Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The language read-only property of the TrackDefault interface returns a default language for an associated SourceBuffer to use when an initialization segment does not contain language information for a new track.
This should be a valid language code, e.g. en-US.
Syntax
var mylanguage = TrackDefault.language;
Value
A DOMString.
Example
TBD
Browser compatibility
BCD tables only load in the browser
