Script adds "dead video" button near "edit" button. "page": page to start from, page # u can see in the special:video page. "start\stop" - start\stop page processing (works on whole page, so actual effect will be deferred).

Output: Note: it will false-positive on non-youtube videos. I'd suggest to recheck every "dead" link manually.
 * top: processed files: file | actual video link
 * bottom: dead files: file | video link

How to it works:
 * get special:video?page=page
 * parse videos to video id (assumed youtube only)
 * get json from youtube through noembed.com proxy
 * check result

code: deadvideo/code.js
