thanks a lot for your patch! i tried it right now and you did a really
nice work.

just two things i saw:

- it doesnt seem to work with videotestsrc, which is displayed when no
camera is attached. we should probably add a workaround here

- the resolution chooser should probably go into the menu on the top

i would really like to include this patch into gnome 2.22, so could you
have a look at those two things and i will ask for a feature freeze
break for that patch.

could you open a bug in the bugzilla system and we go then from there?

yeah, i think that would be the easiest way for now, as processing a
video, which has a larger resolution than 800x600 _could_ be too much
for a cpu

no, thanks to YOU! ;)
