Also why is video id length range 6-11? From what I found, video ids are 11 chars.

What you mean with the trending link? It's not meant to work for /feed/trending, that's not an ID.

Also why is video id length range 6-11? From what I found, video ids are 11 chars.

Because i found that they are between 6-11, at least there may be some old that are 6, don't know.
I any case it's not just some random range chosen by me.

As about youtube.com/HamdiKickProduction?v=DFYRQ_zQ-gk, it redirects to /watch in any way.
I don't believe we can handle any crazy case other there with just regex :D They are pretty good and powerful, but not always.

Trending link is not a valid video url but regex matches this url - youtube.com/feed/trending

Oh, right, got it.

Can you share the reference for this? Here is a link which discusses about it.
