Indeed.

My biggest wishlist feature right now would be an --xid option
that allows the top-level GtkWindow to be a GtkPlug, and plugs
it into the window with the specified X id.  That, the ability
to read standard input, plus a few lines of hack code to make
GtkPlug work inside a Mozilla window, and we'd have a completely
working media plugin for Nauzileon.

I never got far enough to figure out how to get a GnomeApp to
pretend to be a GtkPlug.

I think I was the last person to hack on videoscale.  It should
correctly handle a number of formats, but certainly not all.  It
does handle RGB, although I think just RGB-565 and RGB-8888.
Additional formats are easy to add.  I checked in a patch a few
days ago that makes videoscale very lightweight in the no-scaling
case, roughly similar to colorspace.  There is probably room for
improvement, though.  There are other performance issues with
videoscale, which I can fix if they are important.

Can't this be handled with caps?  I.e., the video output element tries
to resize the sink caps, if it fails, revert to the original size and
center the output.  This would be preferable if the video source is able
to resize the video arbitrarily, e.g., swfdec or v4lsrc.

One could create a single-frame flash animation of the slugs and use
that for the background.  Neatly anti-aliased for any resolution.  Or
use libart directly.
