ola,
pdp_capture was working once with an old version of ImageMagick
but anyway it was too slow,
so now its compilation is made optional,
it is a bit abandonware..
use webcamstudio instead ( http://www.ws4gl.org/ ),
it does the same as gstreamer that Iohannes recommends,
but with an interface...
it will output the screenshots to a vloopback device ..
about the disposition on the screen, no eye deer ..
ahoj!

is there a way to do these screenshots such that they don't actually
show up on a screen visible to the user i.e I don't have to show the
raw Pd patch to the user, only the mix? This is a 2-headed machine
(one machine --- I'll use 2 if I absolutely have to) and the plan is
to show a Gem or pdp window fullscreen on one head and a pdp window
fullscreen on the other. This leaves me not sure where to put the Pd
patch for the screenshots.

a bit complicated, but you can do that by doing screenshots with
gstreamer, send it to a videoloopback device and read that (with pdp,
Gem, GridFlow or whatelse)
- get v4l2loopback (http://code.google.com/p/v4l2loopback/)
compile, install, load the module
- get gst-v4l2loopback (http://github.com/umlaeute/gst-v4l2loopback)
compile (need gst-plugin-base-dev), install
run the gstreamer-pipeline, e.g.
$ gst-launch ximagesrc use-damage=false startx=0 starty=0 endx=640
endy=480 ! queue ! ffmpegcolorspace ! v4l2loopback
access the video using [pix_video], [pdp_v4l2] [#camera] or cat
running here.
this of course only grabs a portion of the screen, rather than a
window
and track that...
