Is it practically possible to have a track with no sample data?
For example, we may want to define one metadata track for storing both Non-timed and Timed Metadata. But, in some case there may not be sample data for Timed Metadata for example non-scalable channel audio.

It would be ill-designed to end up in situations where tracks have no data. I would suggest using tracks for timed data and using movie-level structures for non-timed metadata.

Does movie-level structures for non-timed metadata means a (new) box in equal or higher level than trak box in moov box hierarchy?
