Regex to parse youtube yid

Example URLs

Any regex that will pull the correct YID from all 4 of these use cases? The first case is especially odd.

Thank you.

(?<=v=)[a-zA-Z0-9-_]+(?=&)|(?<=[0-9]/)[^&\n]+|(?<=v=)[^&\n]+

This works. https://i.sstatic.net/J7yXK.jpg

For what it's worth, this worked on http://rubular.com/

(v=|\/)([\w-]+)(&.+)?$

Grabbing second capture group for these:
