That is a good idea, but I don't know if Emacs can do it. I guess it's
easier to use an external command for that. I found some interesting
code in mm-url.el, though it looks like it needs some work.

However, my connection is not good enough for watching movies like
this. There will be end-of-file errors. I might as well download the
whole thing before I watch it.

Another approach that I like better is to play the video file like a
stream. If the player knows what it's doing, it will do buffering for
me, right?

(defun bongo-insert-youtube-url (youtube-url)
  (interactive
   (list (bongo-read-uri "Youtube URL")))
  (with-current-buffer (url-retrieve-synchronously youtube-url)
    (re-search-forward bongo-youtube-video-regexp)
    (let ((real-uri (concat bongo-youtube-base-url (match-string 1))))
      (goto-char (point-min))
      (re-search-forward bongo-youtube-title-regexp)
      (bongo-insert-uri real-uri (match-string 1)))
    (kill-buffer (current-buffer))))

Sadly, it looks like VLC cannot handle this; it barfs on EOF. It does
work all the way with Mplayer. (Not tested with the back-end, I don't
have it installed.)
