Re: [PD] How do you find exposure from pixel or video? - Pd-list

20 Jul 2007

      So i can use the pix_video object?
I have tried and nothing happens when the driver is in 0
but when i switch to 1 pd tells me that
driverID (1) must not exceed 1driverID (1) must not exceed 1
so i have tried to switch to ieee1394 then
error: Bad arguments for message 'driver' to object 'pix_videoNEW'
... you might be able to track this down from the Find menu.
Do you know how can i capture from the ieee1394?
Thanx

err, there's no pdp_ieee1394 on linux,
it only exists for OSX
you have to use Gem

with helpfile i mean:

make the object,
rightclick for the context menue
choose help

those files should explain how to use the objects.
they are patches themselves so you can play around, modify, or just
copy parts of them.
hope this gets you started.

to get the brightness of a live video feed you could use
[pix_video] and [pix_data] from Gem for example.
look into the helpfiles

Welcome!
I am not sure I know what you mean by "finding exposure from pixel
or video", do you mean getting images from a video camera?  For
that you can use pix_video, pdp_v4l, or pdp_ieee1394.
