Hey, Actually i'm a newb...i had some of the following questions: for using the camera do i need to add some path to the file->path section? do i need to change over to pwc? or keep using v4l? which one is required for webcam,mine is :creative integrated webcam. Ultimately i need to use #labeling , but i cant even find it...i have the newest version of gridflow.

Hi Sisil,
I just tried it with a logitech camera and I get a hard crash. The same camera works under Gem. I will be able to try it some more in a couple of days.
As for windows and gf...I think you are better off staying in linux.
Cheers,
Alexandre

I have been trying to run the motion_detect.pd and have been unable to configure the camera. I have installed v4l (format/videodetect.c). Does gridflow support any webcam?(i have a integrated Creative webcam on my laptop.) I read on a forum about some driver for the philips cam. How do i go about installing drivers for camera for gridflow?(i'm a newb...)(can i make any cam other than the philips one, which has drivers ,work?and usually from what source does gridflow get video?).
Thnks, Sisil

does the [#camera] object create? GridFlow adds two hidden lines to the file->path section, as soon as -lib gridflow is really loaded (without any "undefined symbol").
do i need to change over to pwc? or keep using v4l?
"pwc" itself is a driver, whereas "v4l1" and "v4l2" are protocols. the "pwc" driver talks with an app using "v4l1". there are some pwc-specific options in the [#camera] patch, which you can enable using the pwc toggle, but only if you know that the driver is pwc. don't try using the pwc options of [#camera] with cameras that don't go thru the pwc driver.
which one is required for webcam, mine is :creative integrated webcam.
Well, if you want to know which driver is being loaded for your camera, try this command:
lsmod | grep videodev
in my case, this shows:
videodev 33408 1 pwc v4l1_compat 13700 1 videodev
which means: videodev is a driver used by the pwc driver, and v4l1_compat is a driver used by the videodev driver. in the videodev line, you should have the drivers for any usb cameras you are using at the moment, plus drivers for any pci cards and pc-cards you have for that (TV input cards, etc.)
Ultimately i need to use #labeling , but i cant even find it...i have the newest version of gridflow.
this is a separate issue. or two. first, you can test [#labeling] without a camera, so you can fix your camera problems separately from your [#labeling].
BTW, if you use the gridflow cvs, please consider switching to the gridflow svn. I'm thinking about shutting down the gridflow cvs to make sure people who want the most recent gridflow don't trick themselves into thinking the cvs is the most recent. basically, I have replaced cvs by svn, but I left the cvs there just in case.
