Google Summer of Code
by Hans-Christoph Steiner 18 Feb '07

18 Feb '07

http://code.google.com/soc/ Does anyone know if Google is going to run the Summer of Code program again? If so, I'll happily setup the "mentoring organization" part of it. .hc ------------------------------------------------------------------------ Looking at things from a more basic level, you can come up with a more direct solution...

pix_film more questions
by Item State 18 Feb '07

18 Feb '07

hi, sorry i have some more questions regarding pix_film. i understand i have to use pix_film if i need to process the pixel matrix before going into openGL texture renderer. i don't understand the way the rendering is triggered in GEM. in jitter i do a bang down the rendering tree, in GEM i specify a framerate with gemwin or i bang gemwin manually. however, the rendering chain seems to be interrupted if the pix_film object is stopped (when i send [auto 0( ). i want to halt the movie and fade it out to gray, but as soon as i stop the movie, the successive GEM objects like pix_contrast in the attached patch don't get triggered any more. it seems also that pix_film doesn't "fire" events when sending the same frame number repeatedly into the right inlet (like if i switch on the metro in attached patch, nothing happens). also i need to now the current time of the movie (preferably quicktime time refering to the movie's timebase, or milliseconds, or otherwise frame number could do as well). like something equivalent to the [gettime( message with [jit.qt.movie]. i only see a static output for the films's dimension and an end-of-file bang... is it possible to specify looppoints for the movies? thanks again, -sciss- Send instant messages to your online friends http://au.messenger.yahoo.com

Saving abstraction states?
by Vreahli the Audio Bandit 18 Feb '07

18 Feb '07

Heya again - more questions. I'm trying to find a way to save presets or states for a patch in an abstraction within a patch. If I create an array with [table] it gets dumped out. I've read a bit about memento, however I have bad luck with abstractions so I'd rather try to do it by hand. :) How exactly does the [state] object work? Any ideas? I'm less concerned with making multiple presets since I could just hardcode those in to an array, and more concerned with say [synth1 instance1] keeping it's own settings since the last time I tweaked it. :) I also thought about using a separate file for each instance (name it synth1 $0-settings) but that kinda feels a bit like an inelegant hack to me. Thanks in advance for any advice or insight!

Re: [PD] Noop message.
by Chuckk Hubbard 18 Feb '07

Then I'd have to have some idea what the format of the messages will be, and what will be receiving them. If you want certain fields to be optional, perhaps the lines in your text file could use indices; then you could use [list split] to break each line into lists of 2 items, and send these to [; $1-receive $2(. Then if you want no message sent to 4-receive, you don't put "4" in an odd-numbered spot. How objects respond to messages depends on the individual objects, and I doubt anyone will volunteer to recode all of them to ignore a certain message. -Chuckk On 2/17/07, David F.

PD - patches do not display - blank windows
by nathaniel bartlett 17 Feb '07

17 Feb '07

Hello. When I try to load any PD patch, a window pops up - but there is nothing in it and I can't put any PD objects in it. I am running a dual head display via a nvidia card. Any ideas why the patches don't display? Thank you very much. Nate

Dear List, is there a way to write audio into an array at variable speed? Like in tabread4~, controlled by another audio signal (read: phasor~) thanks for ideas, regards,Peter

Playing .flv files
by Jiri Heitlager 17 Feb '07

I am pretty sure that playing .flv files in PD is not (yet) supported. Would it not be a very cool thing, becuase then clips from youtube can be used in projects.. Jiri

GEM - alpha blending of images over movies
by Item State 16 Feb '07

16 Feb '07

hi, i'm trying to port a former jitter patch to pd/gem (http://lists.puredata.info/pipermail/pd-list/2006-11/043853.html). i have problems getting overlayed images to display properly. i have four rectangles fed by pix_movie, then i need to fade in and out a rendered text image. i tried using pix_image -> pix_texture and [alpha 1]. the images are .png with transparent portions. i once got it to display correctly, but now if i open the patch, the videos all show up with wrong colours: http://sciss.de/test/Bild%201.png (see attached patch gemTest2.pd) once i remove the pix_image and pix_texture, save the patch and re-open it, the videos show up correctly again: http://sciss.de/test/Bild%205.png (see attached patch gemTest2B.pd) ... also, i don't know how to fade in the text (the "action" string). is there an alpha-channel multiplier for pix_image? thanks for hints! is it possible to stretch the video so that the rectangle stays the same, but only the top part of the video is shown (vertically zoomed without interpolation, so that you can see the pixels)? ciao, -sciss- Send instant messages to your online friends http://au.messenger.yahoo.com
