Can't download english version on multilingual videos on france.tv #26133

Hi,

I'm trying to download the english version of Doctor Who on france.tv (for example: https://www.france.tv/series-et-fictions/series-fantastiques/doctor-who/doctor-who-saison-11/1829347-la-femme-qui-venait-d-ailleurs.html). If you watch the video in the embedded player, you have to clic on a button to choose the language and the subs. When I list all the available formats, I can see that there are 2 versions for each quality:

I've tried downloading both version for a given quality and both have french audio. Is it possible to have the english version of the audio, or is it something that can only be obtained through the embedded player?

Anyway, thanks for your awesome tool.

Still the case for the new season. e.g. https://www.france.tv/series-et-fictions/series-fantastiques/doctor-who/1874141-la-chute-des-espions-partie-1.html I think that the reason is that youtube-dl is dowloading a m3u8 which contains segments in .ts format with video muxed with French audio. But when using the embedded player, video and audio are received separately and in chunks of dash files. youtube-dl does not use the same source as the embedded player.

More details: The embedded player appears to first get a manifest.mpd file such as the one attached. The URL to get this file can be seen with Firefox debug tools. It contains a key that changes, but the manifest does not change. youtube-dl or ffmpeg with this URL as an argument can download the video and the two audio tracks. I don't know (yet) how to download the subtitles too.
