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!
