Hello,

Firs of all: is there anyone who got install GEM (not extended releseses of pd) in G4 with Mac OS 10.3. How do you made it? Please, explain me.

Now, i will explain my steps (maybe someone can find some error in my installation):

in order to install Gem at a G4 1,5 GHz with 10.3.9, im following the
instructions that come in GEM.README.

• Following the part wich say "do it by hand" i have the next structure:

Applications\pd\extra\Gem.pd_darwin
Applications\pd\extra\help-Gem
Applications\pd\Pd-0.39

• I have found "Gem.pd_darwin" in "gem-0.90.0-OSX-G4-bin.tar.gz"
• "help-Gem" is a copy of "help" folder that comes inside of
  "gem-0.90.0-OSX-G4-bin-doc.tar"

Then, I launch Pd from the Terminal with this command:

open Pd-0.39 -lib Gem

which opens pd, but without any message about Gem.

I have tried with -verbose but nothing happens

tx Megale for your answer, im under OSX and using Pd-0.39.2-extended-test1.app and that's why i pose the question since in linux i know how to locate the webcam, simply /dev/video0..but under os x im simply lost.. i did search what you said an got some patches to play with and see but so far i get this when trying to load [pix_videoDS]

... couldn't create

If i take away the DS part it comes up

pix_videoDarwin: height 320 width 240
pix_videoDarwin: could not make new SG channnel
pix_videoDarwin: could not set SG ChannelBounds
pix_videoDarwin: could not set SG ChannelUsage
pix_videoDarwin: set SG NormalQuality
pix_videoDarwin: Using YUV

but when trying to access any help file or documentation i get this:

sorry, couldn't find help patch for "Gem/pix_videoDarwin.pd"

what means that so far the learning curve, withouth dokumentantion, gets really steep..

thanks for you answer, it opened a way..but please if possible (if you are under OS X) could you share a llittle example patch?

tx,
/kad

pix_film - use a movie file as a pix source for image-processing
pix_movie - use a movie file as a pix source and load it immediately into the texture-buffer

I don't use Gem myself, but reading that it seems pix_movie would load the whole video file into RAM, and probably into the video RAM on the graphics card. Not knowing much about Gem, there may be a difference between "pix for image processing" and "pix for texture", which may or may not be important.
