Hey,
the problem I have, I want to use one video input, double the the image, do two seperate manipulations on it and then combine the two back into one image using gem. If I make two connections from pix_video I get a flashing screen, if I make two gemheads and try to call up the same source, gem thinks I'm trying to make a new video channel.

any ideas?

thnx in advance

Hello there,

I'm running pd_0.40.3_extended on osx. I read elsewhere that pdp should run on it without having to install it separately, though the objects are not working for me (the appear in rectangle of red broken lines). Did I install something wrong? I'm not all that used to going into the terminal (I don't even like computers )

any ideas?

Hello there,

As you might have guessed... I have a problem. I'm trying to make a simple composite of two images in Gem, a still and a video stream. On the I use pix alpha to make part of the image transparant, on the second I do nothing. Then I composite them together using pix_composite.
The problem is that I want to make the first image smaller or bigger. If I just resize it using pix_resize, the two don't match in size anymore and Pix composite wants them to be the same size. The only solution I've found so far is to first first use pix_crop to isolate the part of the image I want and then use resize to scale it back up to the size it needs to be for the composite. This works, but slows everything down beyond usability.
I tried to put a scale object after the first image, but this scales up both images and I only want to scale that first layer.

Any ideas?

much thanks

Hey all,

I'm having a problem with the pix_chroma_key object. It does nothing for me at all. Even when I use the help file and fool around with values, I just don't get any reaction. I looked up people having problems with this object and it seems to be creating problems for more people, but they usually do get some kind of a result. I am aware of the yuv colorspace thing.

If anyone can point out the obvious for me...

pix_separator isn't in the documentation browser for some reason. Works like a charm though.

Thanks.

thanks nestor, I'll try that. I'm curious if it will work with a live video input. Can a separator split a gemlist?

for anyone with the same problem, pix_zoom might be a sollution. Not for me though, I couldn't figure it out either. pdp has a zoom that worked easily though.

got it, sorry for yrrrrr time. If anybody runs into the same problem on osx 10.4, go to the additional installs on your osx install disk and install x11.

I'm getting this in the console :/Applications/Pd-0.40.3-extended-20080318.app/Contents/Resources/Scripts/../extra/pdp.pd_darwin: dlopen(/Applications/Pd-0.40.3-extended-20080318.app/Contents/Resources/Scripts/../extra/pdp.pd_darwin, 10): Library not loaded: /usr/X11R6/lib/libX11.6.dylib
Referenced from: /Applications/Pd-0.40.3-extended-20080318.app/Contents/Resources/Scripts/../extra/pdp.pd_darwin
Reason: image not found

If this helps anybody...

thanx in advance

Thanks for your reply claudius. There's only one thing I don't understand in this approach and have no success with. I guess I'm doing something wrong. When I put both as a separate texture, I can move and scale the object as I want, but the part of the first image that has to be transparent is no longer transparent. When I texture something, geos can't be transparant?

Thanks for the reply, I'll try that. Never thought of it because the help patch didn't mention it and other blending objects often don't need it.

I'll let know if it works
