Overview

Some alternate tracks contain something other than a direct translation (or untranslated written form) of the primary content. Commentary tracks are one example. Don’t automatically select these tracks. The presence of the Track Exclude From Autoselection atom in a track indicates not to automatically select this track.

Ensure that such tracks have user-readable names that help users to identify the purpose of the track. These names are stored in one or more track name ('tnam') atoms, each translated into a different language, within a user data ('udta') atom within the 'trak' atom.

The type of the Track Exclude From Autoselection atom is 'txas'. This atom, if used, must be somewhere after the 'tkhd' atom.
