I love this when rickroll is covered

Another approach is to first verify that the string contains a YouTube domain:

/(?:https?:\/\/(www.|m.)?)?(?<domain>youtu.be|youtube.com)(?:\/)/

Then pick out the data you're looking for. For me, I'm only interested in the video ID:

/((?:\/|v=|vi=|v%)(?<id>([\-\w]){10,14}))/

Thanks @rodrigoborgesdeoliveira for your URL list!
