Description

I try to download a video from replay service of France.tv (french public TV). Here's an example :
https://www.france.tv/france-3/lego-ninjago/saison-3/1096127-ninjago.html

It worked welll in the past.
Now, I've got the video.
But I have only 10 seconds of the audio, since 0:00:11 there is no sound.
In the streaming video, there is sound for the whole video.
If I try to download only the audio (with the -x parameter), the m4a file is only 10 second.

[zag-adka]

It is the same problem that I've described in issue #22674
