Question

Does someone have a regular expression that gets a link to a Youtube video (not embedded object) from (almost) all the possible ways of linking to Youtube?

I think this is a pretty common problem and I’m sure there are a lot of ways to link that.

A starting point would be:

• http://www.youtube.com/watch?v=iwGFalTRHDA
• http://www.youtube.com/watch?v=iwGFalTRHDA&feature=related
• http://youtu.be/iwGFalTRHDA
• http://youtu.be/n17B_uFF4cA
• http://www.youtube.com/embed/watch?feature=player_embedded&v=r5nB9u4jjy4
• http://www.youtube.com/watch?v=t-ZRX8984sc
• http://youtu.be/t-ZRX8984sc
• … please add more possible links and/or regular expressions to detect them.

So far I got this Regular expression working for the examples I posted, and it gets the ID on the first group:

http(?:s?):\/\/(?:www\.)?youtu(?:be\.com\/watch\?v=|\.be\/)([\w\-\_]*)(&(amp;)?‌​[\w\?‌​=]*)?
