This page is not complete.

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The TrackDefault interface provides a SourceBuffer with kind, label, and language information for tracks that do not contain this information in the initialization segments of a media chunk.
