Ip matcher in ip rotation to prevent 403 (youtube)

[WeeeeeeeeeeS]

(I couldn't implement it)

So now, Google videos return an IP allowed to access the actual playback in the playback URL (in some regions, though I think it will roll out to everyone soon) (This happens if you don't provide any authorization, cookie, oauth..)

It would be nice to have an option to enable some sort of IP matcher that tries to extract the required IP from the playback link. For reference, here is the relevant code: link.

Playback example: "https://(server).googlevideo.com/videoplayback?expire=(expire)&ei=(randomStuff)&ip=2001%....&id=(randomStuff)..."

Writing the IP extractor is easy, but I couldn't implement it.
