How to access text files, hidden behind 'm3u8' resources

[Pavel_47]

Hello,

yt-dlp downloaded doesn't differentiate between 2 subtitles of the same languages: when specifying language code (e.g. 'fr') it takes by default the file let's say "for the deafs", where all conversations are subtitles - not just conversation in different (from 'fr') languages.
When exploring video resource info (with the same yt-dlp) we can differentiate two version of the same languages. They are hidden behind some 'm3u8' resources. Does someone aware of a method how to exploit these 'm3u8'.
Here is example:

import yt_dlp
link = 'https://www.arte.tv/fr/videos/107115-001-A/la-fille-de-kiev-1-6/'
ydl_opts = {}
with yt_dlp.YoutubeDL(ydl_opts) as ydl:
    info = ydl.extract_info(link, download=False)

for k, v in info.items():
	if k == 'subtitles':
		for k1, v1 in v.items():
			if k1 == 'fr':
				for item in v1:
					for k2, v2 in item.items():
						print(f'{k2:<20}{v2}')

Here is output:
