in Gem you could use [pix_dump] and [pix_pix2sig~] to get the pixel values.

so all in all: all of the "still alive" video frameworks for Pd support 
this operation. so choose the one you are most familiar with.
i would suggest not to mix several frameworks if you have no reason to 
do so (especially Gem is a beast, as it demands the existance of a 
gem-window in order to work properly; pdp and GridFlow do not have this 
limitation (to my knowledge))

should be http://gridflow.ca (haven't checked though)
