Play videos from a browser to VLC

[dinextra]

Is there way to have VLC play videos currently being played in a browser regardless of what site I'm on? I know that I can copy+paste URLs from Youtube, Dailymotion and so on, but this doesn't work with all sites who video playbacks.
I'm assuming I would need a browser extension to detect the video URLs, right? I'm just wondering if VLC can do that itself without the need of a browser extension.
