This and all fixes like it haven't been working for me. The video I wanna stream pops up for less than a second and then immediately disappears without any error message. Link to video in question: https://www.youtube.com/watch?v=7takIh1nK0s I have tried both this one and the "share" link neither work and they both do the exact same thing as described above.
This is an age restricted video. There's no way that vlc can bypass that kind of restriction.

More often than not it's just the channel trying to identify users by forcing them to sign in to youtube to view a video.
