GEM: openGL and CPU usage
by Martin Dupras 29 May '03

29 May '03

I'm working on some VJ-type pd patches at the moment, and am a bit puzzled by how GEM uses openGL, and what is processed on the CPU. Hewlett-packard is lending us a twin 2.8GHz Xeon machine with 1gig of DDR ram, which is fitted at the moment with a matrox G400 (don't ask, we've got a GeForce 4 Ti4600 card coming our way imminently.) I was doing some testing using gem and pd, playing with a large avi divx file (ca 500MB). If I use pix_movie and use it to display on a rectangle geo, the movie plays fine. If however I apply any transformations, the whole thing slows down considerably. I understand that it must be because of the graphics card. Can anyone elaborate a little on how GEM exploits openGL, and what objects use the CPU for processing? I would in particular know what kinds of approaches would help get good video processing performance. Here's another question. If I apply two videos to two rectangles, put them in front of one another, and make the frontmost one half transparent, the black pixels are not transparent (in other words, they are grey and half opaque). I suppose that must be to do with how openGL works, but is there a way to make it behave in such a way that a pixel that has no color is actually transparent? - martin

Dumping [coll] contents to a text file
by Michael J Berkowski 29 May '03

29 May '03

Greetings, I am fairly new to PD and am looking for a way of dumping the contents of a [coll] to a text file, without the index value at the front, and inserting a carriage return after each coll index. The purpose of this is algorithmic score generation for Csound, and I had been doing this in Max-MSP with the [text] object, packing in a "cr" with each list. In PD, I have had to copy the coll's contents to a text editor, save them, and import them into MS-Excel with delimitations to remove the index value-->not very efficient. Is there an object/external in PD which acts similarly to [text] in Max? Does anyone have a better suggestion than this entirely? Thanks very much Michael Berkowski berk0081(a)tc.umn.edu

[Fwd: [v2v] stream started...]
by Rama 29 May '03

29 May '03

hi pd'ers, here's some info about an independent media meeting around G8's meeting @ Evian these days. We (a team from Barcelona) will get to Geneva by van tomorrow and will try to run an mp3 streaming (would love ogg, though) using pd with a patch to mix incoming streams, plus ogg tracks on hd, plus soundcard input.. there will also be some "Real" streamings, but it's clear we need free software asap.. anyone could achieve interesting results with pd/pidip/ffmpeg? there are projects from local radios emitting RF to pick us from the net and put in the air. anybody willing to do their stuff in here or be around and help check/redistribute is very welcome we are hoping to have spanish web+ resources about pd, we'll tell more when we have news. what about a kind of webapp to share patches, abstractions, etc? if someone knows about such a piece of software it would be really interesing. if not we can probably work it out. we will be publishing information @ http://barcelona.indymedia.org write back for any need see you around! r -----Mensaje reenviado----- From: Florian Schneider <fls(a)kein.org> To: v2v(a)mail.kein.org Subject: [v2v] stream started... Date: 29 May 2003 15:34:08 +0200 GENEVA 03 livestream http://www.geneva03.org/static/live.ram GENEVA03 livestream is a temporary autonomous TV project broadcasting during the days around the G-8 summit in Evian. It will cover the mass protests and blockades in the area of the Lac Leman in Switzerland. From May 29 to June 3, a continuous livecast will be streamed on the internet and picked up and redistributed by local and international broadcasters, as well as projected in streets, bars and theatres around the globe. GENEVA03 livestream presents live reports from the rallies and manifestations, protests and blockades as well as studio debates and talk shows, movies and meetings, parties, vj- and dj-sessions and concerts. The GENEVA03 livestream studio is hosted in the cultural center l'usine in the very center of Geneva <http://www.usine.ch>. The video stream produced in the theatre will be screened around the clock in the cinema next door. In order to cover the protests between Geneva, Lausanne and Anmasse in real time, media activists will work from the "EVERYONE-IS-AN-EXPERT" mobile studio van, which - with a self-adjusting bi-directional satellite dish - will provide a mobile internet connection and transmit live-footage from the roaming protests. For GENEVA03 livestream net-activists, indymedia reporters, independent filmakers and videographers from many different countries have joined together in order to explore new forms of collaboration in film and videomaking. "Long-term we believe that we can assemble a sustainable and scalable platform for audio-visual materials of a critical and independent nature", the initiators say. Some days before the G-8 summit they set up V2V, a video filesharing network. The idea of V2V is to share video material of a reasonable quality and to guarantee its availability within the most popular filesharing networks (edonkey, gnutella, bit torrent) through a network of dedicated servers that mirror the material until such time as it has spread widely in the P2P-networks. Each file is accompanied by metadata in an xml .info file and produced as an searchable RSS feed for people to integrate into their own sites and is also published on its own websites. <http://v2v.indymedia.de> V2V suggests a set of specifications for the encoding with half of the standard broadcast quality as a compromise between a modest upload-time and a tolerable resolution for screening, in order to facilitate the global exchange of images. <http://v2v.indymedia.de/static/info.shtml#vp3> V2V began at the end of May 2003 with the participation of half a dozen servers. In the context of the GENEVA03 livestream the V2V video sharing network will be tested as a tool for production, distribution and archiving. Works to be delivered over the V2V system will vary from quickly edited footage suitable for use as a stock archive to finished films and documentaries. The activists are calling groups and individuals to join the V2V server-network and to contribute footage locally and remotely.

Re: [PD] PD Launcher/External Manager
by bbogart＠ryerson.ca 29 May '03

29 May '03

Yes, The PD launcher will allow you to do this, but not through rc config files, but runable scripts/shortcuts on all platforms. These scripts are generated by the GUI, but are meant to be used outside of the GUI context, so you set up a number of PD "configs" for different purposes, and then run those specific scripts to do what you want. one can always edit the scripts themselves as well, except those windows shortcuts.

more osx strange stuff
by Matthew Nish-Lapidus 29 May '03

29 May '03

i just noticed one more really strange and really bad behavior on osx. all my abstractions that used $0 for send/receive in gui objects are getting very messed up. if i had a toggle set to send $0-click in my abstraction on windows, when i open it in osx the name has been saved as 1051-click. this is really frustrating. i have to go in and manually change each one. i tried doing a search/replace in the .pd file in a text editor, but it didn't work. the patch still loads with the wrong values. matt.

./configure & tcl/tk question on OSX
by tigital 29 May '03

29 May '03

hiya, ...I'm trying to recompile pd 0.37-test4 for mac against the newly compiled tcl/tk 8.4.3...the thing is, when I run ./configure, I get the following: checking for X... libraries /usr/X11R6/lib, headers /usr/X11R6/include checking for XCreateWindow in -lX11... yes checking tcl.h usability... yes checking tcl.h presence... yes checking for tcl.h... yes checking for main in -ltcl8.7... no checking for main in -ltcl8.6... no checking for main in -ltcl8.5... no checking for main in -ltcl8.4... no checking for main in -ltcl8.3... yes checking for main in -ltk8.7... no checking for main in -ltk8.6... no checking for main in -ltk8.5... no checking for main in -ltk8.4... no checking for main in -ltk8.3... no checking for main in -ltk8.2... no checking for main in -ltk8.0... no ...this seems kinda weird, and then I notice that it was looking for X11 (I prefer to use tcl/tkAqua for native graphic support)...so, is the configure script looking at some other tcl/tk install (fink perhaps?) other than the one in my /Library/frameworks? If so, how can we fix this? tanx, jamie
