Re: Movie text tracks

[Devin Asay via use-livecode]

Sorry, I left out the punch line.

My original need was simply to extract the text tracks from the old .mov files. 
It turns out you can do that, after a fashion, with QT Pro, but it comes out 
with lots of binary cruft. I found out you can also do this with ffmpeg, the 
Swiss Army Knife of video tools. This website explains how:

https://forum.videohelp.com/threads/403944-Extract-and-convert-QuickTime-7-Pro-TextTracks

Neither method was perfect, but both were good enough for what I wanted.

So, both Jacque’s and Richmond’s suggestions were good, but too much work for

actually still runs QT 7, and I have an old QT Pro license key for Windows. I 
wonder if it still works. (Spoiler alert—it does!) So I was at least able to 
open up the movie files. Score 1 for Microsoft and backward compatibility! And 
there, magically, were my text tracks!

Paul, I think your suggestion to encourage LiveCode to support text track 
access that exists in the modern AV frameworks is a great one. Maybe timely, 
now that the mothership has asked for top 10 bug fix requests again.

Richard, thanks for pointing me in the direction of HTML 5. It set me on a 
little journey to educate myself on the state of video captioning in *this* 
century! Definitely glad I took that little detour and learned about WebVTT 
captioning format.

Thanks again for the help and suggestions. This community never disappoints!

Good to see you here, Devin.

If your app can handle the RAM hit of embedding a browser app instance 
with the Browser Widget, and if you can extract the text track info from 
QT's proprietary format, HTML supports text tracks nicely via the WebVTT 
standard:

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!)

Re: Movie text tracks

[Paul Dupuis via use-livecode]

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.
