Kaspar, just stumbled over youtube-dl not being able to download a video. It's almost exactly a month since you've noticed the new api. Thanks for reporting! Despite the old api is still working, some videos are not accessible through it.
Since your initial patch something has been already altered and simple https://static-cdn.arte.tv/guide/manifest.js is not available anymore. For now I was able to look up the token in browser.

I wasn't aware. So far I assumed that this new API need would be something for the future.

I kind of assumed that it couldn't have been so easy. The PR is not finished anyway, so this code can't work as is... I just did not get around to continue yet.

Knowing that it might become more important to have the new API, might work as a better motivator to do so, since I'm regularly using this extractor myself. 😉

However: in case you have anything to contribute to this PR... I don't see this as a solo mission. So if that's the case I might have to give you access right to my fork, so you could push to the branch.

I hope you don't mind. I've updated this from a working WIP extractor back-ported from yt-dlp.

I hope you don't mind. I've updated this from a working WIP extractor bac-ported from yt-dlp.

Not at all, go ahead. I forgot this even exists.

Thx for finishing it.

Great, thanks.

I see that somehow the yt-dlp code didn't need to get the Bearer token, which makes things easier.
