Description

Age restricted youtube videos fail to download now. I wonder if it's a regional thing, I'm in russia.

[dstftw]

You must authenticate for age-gated videos.

[aearil]

Actually, it seems age-gated videos are accessible via youtube embed links. Could youtube-dl use this to allow downloading without logging in ?

[dstftw]

Again: age-gated videos are no longer accessible without logging in.

[mpfaff]

@dstftw that isn't true. I use the Boost for Reddit app, and it uses an embedded YouTube player, which can be used to watch age restricted videos without logging in.
