YouTube URL algorithm?

Question

How would you go about generating the unique video URL\'s that YouTube uses?

Example:

• http://www.youtube.com/watch?v=CvUN8qg9lsk

Answer 1

I don't think that the URL v parameter has anything to do with the content (video properties, title, description etc).

It's a randomly generated string of fixed length and contains a very specific set of characters. No duplicates are allowed.
