I only used a webcam with pd but my experience is limited (mostly
because everything just worked out of the box for me). AFAIK there
are some issues with newer cameras that are only supported by v4l2.
In any case, there are several packages that support a camera input:
GEM, pdp (which you probably already know) and gridflow
( Gridflow is a matrix based image processing

In GEM, [pix_video] is your friend. The help file shows you haw it
should be used.
In pdp [pdp_4l] or [pdp_v4l2]
in gridflow you use [#camera]. I know that some new functionality in
terms of interfacing with various camera drivers has recently been
added to gridflow so there are chances that your webcam will be
supported. Also, gridflow's [#camera] is an abstraction which, when
opened, gives you quite a few options for user-friendly

Note, that if you are mostly interested in GEM, [pix_video] does not
work for you but either pdp or gridflow does, there a bridges for
exchanging between pdp and GEM or gridflow and GEM.

HTH... although I know it's vague...
