Re: [PD] videoPYLON C++ update needed

Just in case I send you a new Segmentation Fault log.
Here I have already no method for Gemstate.
I send you the patches to have a better idea what I am trying to do.
trackerping.pd is the main patch, containing filecontrol.
after gemwin is rendered, open languagechoice.pd
there are 2 cameras placed in the main window sending to the pd ping1 and
pd ping2 to languagechoice.


Basically the 2 cameras are creating one touch surface by placing them one
above the wall facing down, the other one facing to the wall. When camera1
gets the wall hit tells the event to camera 2 which gets the position x y
from pix_blob. Now when the 2 cameras send to each other info about the
presence of an object, I get the segmentation fault.
