Description

https://www.youtube.com/watch?v=h4kdqwdbZZ8

this video has 2 sets of english language subtitle tracks—one which only subtitles french-language sections, and one which is full closed captions (which is the one i really want).
youtube-dl only detects and downloads the former and does not detect or download the full cc track, even with the --all-subs flag

I've had this issue too.
