pd 0.42 problem with fa-101
by ypatios 26 Jan '09

26 Jan '09

Hi all :-) I tried the new pd vanilla and there seems to be a problem with my fa-101, which worked fine with all the previous versions of pd (on windows). The Problem: After i set the audio settings and close the window, nothing does seem to work, and when i reopen the window to see what the problem is, the name of the fa asio driver is gone. Furthermore, all the others are gone too! (like the realtek ..) Does anyone have similar problems? (i'm on vista at the moment..) thank you alabala -- ypatios

i use RGBA then :) thanks IOhannes for explainations, now i get it. i had the same issue with different video formats including all the movies that come with Gem, so maybe there might be a bug for real... please tell me if you need more infos about this..

HI everybody, thanks to all, i solved the issue. But is still not clear to me what's happening. I mixed the different suggestions you gave me (cause independently no one was working) and i got this: [gemhead] | [pix_film]/[colorspace RGB( | [pix_alpha] | [colorRGB] | [alpha] | [pix_texture] | [rectangle] it looks a bit weird but it's working and my cpu is drinking a coffee while i mix four videos of 160/200mb each. but I'm really keen to understand where was my problem... as Philippe said i have to send the [colorspace RGB( message first and then load videos. [pix_alpha] seems to be the obj making the work done, but anyway i had to add [colorRGB] to be able to change transparency. @IOhannes: i'm on windows xp pro. do you think it could be because of this? what do you mean with video-importer? thanks..

Alpha+pix_film
by info＠thesaddj.com 26 Jan '09

26 Jan '09

Hi all, here is Marco, this is my first post.. glad to be here. i'm trying to use the [alpha] object to mix different videos using OpenGL. I followed tutorials, checked the forum and the list but i still have this problem: I can change the transparency of a geo without texture, and everything works also when i load images. But when i add [pix_film] or [pix_movie] and i load a video the geo itself disappears - if alpha is on - and appears again (displaying correctly the video) when alpha is off. I also tried to change [pix_texture] with [pix_texture2] and [rectangle] with other geos, but nothing... I think this is pretty strange. this is my basic patch not working: [gemhead] | [pix_film]X[t f] | [pix_texture] | [alpha] | [colorRGB] | [square] Cannot understand if it could be a problem of my graphic card - ATI Mobility Radeon X1600 - or something else. I work - unfortunately - on windows xp pro, with pd-extended latest stable release. i didn't have the chance to try the same on another computer, by now. Thanks a lot to everybody.. cheers... Marco

For dynamic patches: "pd make clean" message
by João Pais 25 Jan '09

25 Jan '09

Hi, a suggestion that probably was already spoken of here: some patches have a have a steady core, but a dynamic behavior. A simple example is attached of a patch whose goal is only for graphical display. But other patches might have a more complex behavior, and depend on on-the-fly parameters. For example, a patch with a graphical eq that changes the number of bands dynamically, and automatically displays them graphically. That to say, these patches are already "complete" when the basic code is given - this code than lets the patch reformulate itself to other configurations. If you agreed with what I said so far, you should agree that it is weird that when closing these patches, they're marked as "dirty", and pd asks for them to be saved. I guess it would make sense to add a "pd make clean" command or something that restrains pd from asking the patch to be saved. The patch I send gets dirty every time it is initiated due to the donecanvasdialog message. Which means that if you're using this kind of button 20x in your patch, you'll get 20 "save changes" messages. People can argue that it's possible to close the main patch with ctrl-shift, but that's itself a dirty solution - and sometimes makes pd crash, at least in windows. I suggest a "pd make clean" message, but maybe someone has a better idea. Best, JoÃ£o Note: sooner or later, this patch will be in the jmmmp library. -- Friedenstr. 58 10249 Berlin (Deutschland) Tel +49 30 42020091 | Mob +49 162 6843570 jmmmpais(a)googlemail.com | skype: jmmmpjmmmp

hello, for pix_opencv you must add [pix_rgba] in help-example " In order to make the pix_opencv objects work You always had to set colorspace RGB. otherwise, You will not see any effect." my first test : http://tinyurl.com/7yor85 p. ----- Mail Original ----- De: "Loic Kessous" <loic.kessous(a)gmail.com> À: Pd-list(a)iem.at Envoyé: Vendredi 23 Janvier 2009 12:13:21 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne Objet: [PD] (no subject) Hi All, I found that there is a Pd library called pix_opencv in the pd- extended source folder, but I can't load (red dot line box) the externals with the already compiled app that I found here : http://puredata.info/downloads/ Mac OS X Intel (Mac Pro, MacBook, all Intel Macs) http://downloads.sourceforge.net/pure-data/Pd-0.40.3-extended-macosx104-i38… does that mean that it is not working yet? or just that it's not yet in the official distribution?

Hi Marius, thanks for the answer, i tried in the order you suggested but i have the same effect. With 'alpha on/off' i mean sending 1/0 with [tgl] to the left inlet of [alpha]. I tried also different video formats (including the homer.avi in gem examples) but nothing. I made a new patch only to find the bug in this process, so i don't have any more objects that the ones that i draw in the previous e-mail and the [gemwin] with its proper messages. really strange...

[PD-announce] New Book: FLOSS+Art
by propaganda＠goto10.org 23 Jan '09

23 Jan '09

echo -n "sorry for ><," while true; do echo -n " please >>" done -- WHAT: What does Free and Open Source software (FLOSS) provide to artists and designers - beyond just free alternatives to established tools from Photoshop to Final Cut? "FLOSS+Art" is the first book to answer this question. It shows how the value of Free Software lies in its differences and creative challenges, as opposed to out-of-the-box and off-the-shelf solutions; how it allows to work and collaborate differently with computers, and therefore enable different kinds of art and design. The Internet - whose infrastructure is based on free software and open standards - is an obvious example of such an adaptable, collaborative artistic medium. "FLOSS+Art" also covers more traditional artistic domains such as graphic and audiovisual design, and how they shift from customer-centric to community-driven work. FLOSS+Art critically reflects on the growing relationship between Free Software philosophy, open content and digital art. It provides first-hand insight into its social, political and economic myths and realities. With contributions by: Fabianne Balvedi, Florian Cramer, Sher Doruff, Nancy Mauro Flude, Olga Goriunova, Dave Griffiths, Ross Harley, Martin Howse, Shahee Ilyas, Ricardo Lafuente, Ivan Monroy Lopez, Thor Magnusson, Alex McLean, Rob Myers, Alejandra Maria Perez Nuñez, Eleonora Oreggia, oRx-qX, Julien Ottavi, Michael van Schaik, Femke Snelting, Pedro Soler, Hans Christoph Steiner, Prodromos Tsiavos, Simon Yuill.
