Description

I'd like to download a playlist on the site franceculture.fr. Right now it downloads only the first episode.

For example, a four episodes emission :

youtube-dl --yes-playlist https://www.franceculture.fr/emissions/la-fabrique-de-lhistoire/histoire-des-anarchies  -v -J

It seems that the extractor is not even looking for a list.

Please tell me if I can help. If you point me to a simple extractor with playlist support, I could try to copy and adapt it.

I suppose the same is true for other "radiofrance" websites, like franceinter, but I've not tested yet.

Best regards, thanks for the huge work ! :-)

@dstftw Sorry to waste your time, but could you point me to the duplicate ? I couldn't find any. Regards
