Using yt-dlp options in Python

[Pavel_47]

This mean that they have not made Spanish official available,if need that have try to scrape from eg FireFox.

I meant here that somewhere on the resource there is a French .vtt file, which works as follows:

• It subtitles (in French) the speeches in Spanish, e.g. when Pedro Almodóvar and Antonio Banderas speak Spanish
  
• It does not subtitle the speeches in French, e.g. when the background voices speak in French
  

Such a file exists on the resource, you can access it using "Web Developer Tools" in Firefox.
This file contains the sentences in French that coincide with the speech in Spanish. When the background voice speaks in French, there are no subtitles.
The question is how to access this file from yt-dlp
I didn't mean I was looking for Spanish subtitles!
