This is not any sort of immediate help, but a quick Google search
suggests that both AVF (Apple Video Foundation) and MMF (Microsoft Media
Foundation - the underlying framework for the player in Livecode 10)
support classes and APIs to access multiple media tracks and metadata. I
don't know about Mobil player support (or Linux), but now is the time
while Livecode 10 is in developer preview stages to lobby Livecode Ltd
to broaden the player object to support more cross-platform features. I
suggest opening an enhancement request at https://quality.livecode.com/
for text track access (subtitles are an accessibility requirement on
lots of media these days) for LC 10.

Hi all,
I’m resurrecting some QuickTime movies from years ago, and some of them have
text tracks. (Remember those?)
In the LC player object you can still see that there is a text track with `put
the tracks of player 1`. But there doesn’t seem to be a way anymore to show
text tracks, either in the player object or in QT Player. All of the hits I get
on the topic in a DuckDuckGo search are 15 - 20 years old.
Anybody know how to show, or at least recover, old text tracks from video files?
(Man I hate it when the technology gets *less* capable!)
