Using xwidget to play youtube videos

[Lars Ingebrigtsen]

To start playing around with xwidget in eww, I looked at what xwidget
was doing, and I basically ended up with:

(defun eww-tag-iframe (dom)
  (when (fboundp 'make-xwidget)
    (require 'xwidget)
    (let ((xw (xwidget-insert 1 'webkit-osr  (current-buffer)
                              (string-to-number (dom-attr dom 'width))
                              (string-to-number (dom-attr dom 'height)))))
      (xwidget-webkit-goto-uri xw (dom-attr dom 'src)))))

And it works!  Youtube is playing away.  But I get the follwoing:

Debugger entered--Lisp error: (wrong-type-argument xwidgetp nil)
  xwidget-resize(nil 976 674)
  xwidget-webkit-adjust-size-to-window()
  xwidget-webkit-adjust-size-dispatch()
  xwidget-webkit-callback(#<xwidget > document-load-finished)
  xwidget-event-handler()
  funcall-interactively(xwidget-event-handler)
  call-interactively(xwidget-event-handler nil nil)
  command-execute(xwidget-event-handler)

Since I haven't requested any resizing of my widget, that's a bit
surprising.

(defun xwidget-webkit-adjust-size-to-window ()
  "Adjust webkit to window."
  (interactive)
  (xwidget-resize (xwidget-webkit-current-session) (window-pixel-width)
                  (window-pixel-height)))

So...  (xwidget-webkit-current-session) is nil?  I tried grepping
through the xwidget documentation for "session" but didn't see anything
obvious...
