I went through the list at
https://www.w3.org/community/inbandtracks/wiki/Main_Page#ISOBMFF_2 and picked
all those that were marked as "TextTrack". This is about how to identify that a
track is indeed a text track, so if that's wrong, let me know what else I
should write.

If these are not sufficient, can you please let me know how to identify a text
track of kind @metadata in MPEG-2 TS.

That's what the patch says, too.
