Call for entries: Piksel05

||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| -- Piksel05 - october 16-23. 2005 -- call for participation -- deadline 15. august 2005 ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Piksel[1] is an annual event for artists and developers working with open source audiovisual software tools. Part workshop, part festival, it is organised in Bergen, Norway, by the Bergen Centre for Electronic Arts (BEK) [2] and involves participants from more than a dozen countries exchanging ideas, coding, presenting art and software projects, doing workshops, performances and discussions on the aesthetics and politics of open source. Piksel05 will take place in Bergen october 16. - 23. 2005. The development, and therefore use, of digital technology today is mainly controlled by multinational corporations. Despite the prospects of technology expanding the means of artistic expression, the commercial demands of the software industries severely limit them instead. Piksel is focusing on the open source movement as a strategy for regaining artistic control of the technology, but also a means to bring attention the close connections between art, politics, technology and economy. One of the results of the past Piksel events is the initiation of the Piksel Video Framework for 'interoperability between various free software applications dealing with video manipulation techniques'[3]. Piksel05 will also feature the release of the Piksel LiveCD[4], a Linux distribution containing the software used and developed at Piksel. The package contains a suite of innovative audiovisual and artistic software, free video plugins, and documentation from the past Piksel events. |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| open CALL for PARTICIPATION The last two Piksel events has focused on live art/audiovisual performance, but for Piksel05 the main focus will be an exhibition in collaboration with Hordaland Kunstsenter[5]. For the exhibition and other parts of the program we are interested in submissions in the following categories: 1. Installations and interactive work Audiovisual installations created and run solely using open source software. The theme for the exhibition will be loosely related to 'games' and the gaming experience. 2. Audiovisual performance Live art realised by the use of open source software. 3. Software Innovative artistic tools or software art released under an open licence. Please send documentation material - preferably as a URL to online documentation with images/video to piksel05(a)bek.no Deadline - august 15. 2004 Use this form for submitting (or go to the online form at http://www.piksel.no/piksel05/subform.html): |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 1.

That last mail about abstractions was me being lazy and stupid. I just added the abstractions folder to the path and of course it works. Thanks again for the help. I will now make a how to doc for all the ccrma users to get this running. cheers dominic On Tue, 2005-06-14 at 00:19 +0200, Yves Degoyon wrote: > dominic wrote: > > >hey thanks, > > > >Im nearly there, I installed the so > > > >got rid of the Werror (should have remembered that) > > > >And it all went ok until > > > >#check if pd is installed. if this fails make install will stop here. > >install -m 755 pdp.pd_linux /usr/lib//lib/pd/externs > >install: cannot create regular file `/usr/lib//lib/pd/externs': No such > >file or directory > >make: *** [install] Error 1 > > > > > > > > you don't really need to install it : > > make a manual copy copy /where/you/like > > and start pd with '-path /where/you/like -lib pdp' > > the same for pidip. > > ciao, > sevy >

Yep that did it! It works. the jobs a good un. You rule. Thank you very much, its lovely to see that little square of noise again. (don't have a camera to play with at the moment) Just one wee thing though (sorry) lots of boxes are not wiring up pdp_blur, pdp_grey etc. Is this just a problem with the abstractions being in the wrong place or have i missed something when making it? dominic On Tue, 2005-06-14 at 00:19 +0200, Yves Degoyon wrote: > dominic wrote: > > >hey thanks, > > > >Im nearly there, I installed the so > > > >got rid of the Werror (should have remembered that) > > > >And it all went ok until > > > >#check if pd is installed. if this fails make install will stop here. > >install -m 755 pdp.pd_linux /usr/lib//lib/pd/externs > >install: cannot create regular file `/usr/lib//lib/pd/externs': No such > >file or directory > >make: *** [install] Error 1 > > > > > > > > you don't really need to install it : > > make a manual copy copy /where/you/like > > and start pd with '-path /where/you/like -lib pdp' > > the same for pidip. > > ciao, > sevy >

We will gladly accept works that employ live streaming, PureData ,Max/MSP patches and video. Artworks will be projected onto the 2nd storey windows of the Artengine lab during the evening (on the corner of York and Byward). The audience will be artists, art lovers and the masses of unsuspecting locals, tourists and nightlife seekers who pass by our central location every evening. Works will also be presented on small monitors in the stairwell of the Mercury Lounge (downtown down lounge). Deadline for submissions: June 20th Submissions should include: -Artist statement -Documentation of project -technical specs Please keep in mind that we will not be able to accommodate any sound components for this series.

pdp install on fc3 ccrma machine
by dominic 13 Jun '05

hi list, I am currently trying to install pdp (cvs sourceforge) on a fc3 ccrma machine. I am unsurprisingly hitting a few snags and I wondered if I could beg a few sage words from this list. I have installed libgsl and gsl-shlibs When i .configure it seems to go OK for a while then tells me: checking for lqt_decode_video in -lquicktime... no libquicktime not found: not building pdp_qt When I do locate libquicktime it finds all of this: /usr/lib/libquicktime.so.0 /usr/lib/libquicktime1394.so.0.0.0 /usr/lib/libquicktime /usr/lib/libquicktime/lqt_vorbis.so /usr/lib/libquicktime/lqt_mjpeg.so /usr/lib/libquicktime/lqt_audiocodec.so /usr/lib/libquicktime/lqt_opendivx.so /usr/lib/libquicktime/lqt_png.so /usr/lib/libquicktime/lqt_rtjpeg.so /usr/lib/libquicktime/lqt_videocodec.so /usr/lib/libquicktime/lqt_dv.so /usr/lib/libquicktime /usr/lib/libquicktime1394.so.0 /usr/lib/libquicktime.so.0.0.0 /usr/share/doc/libquicktime-0.9.3 /usr/share/doc/libquicktime-0.9.3/README /usr/share/doc/libquicktime-0.9.3/COPYING /usr/share/doc/libquicktime-0.9.3/TODO /usr/share/doc/libquicktime-0.9.3 /var/cache/apt/archives/libquicktime_0.9.3-2.rhfc3.ccrma_i586.rpm obviously no lqt_decode_video there though. Is this the correct version of libquicktime for pdp? any ccrma users out there who understand how its all put together and what version fernando uses?(i will post this to the ccrma list also) Anyhow I thought I would attempt to make it anyway just for kicks. It didn't work and the main info I get is: pdp_imageproc_common.c: In function `_sign': pdp_imageproc_common.c:292: warning: use of cast expressions as lvalues is deprecated make[2]: *** [pdp_imageproc_common.o] Error 1 make[2]: Leaving directory `/usr/lib/pd/externs/pdp/system/image' make[1]: *** [common] Error 2 make[1]: Leaving directory `/usr/lib/pd/externs/pdp/system' make: *** [pdp_all] Error 2 If you got this far, thank you. If you can help I would be very great full. If you need anymore info let me know. Dominic P.S. Derek don't get mad I still have the Debian machines you and Aymeric built and they work like a dream, this is a new box I am playing with.

Re: [PD] pdp v4l problems
by Andrew Cavers 13 Jun '05

13 Jun '05

Hi list. My first posting! I've only recently started using PD. I'm trying to get some basic motion detection working using PD+PDP+PiDiP. Anyway, I'm new to Linux as well so I thought I was doing well when I got PD + PDP + my webcam (a Logitech Quickcam 4000 Pro) working. But... The problem is with the webcam - it works perfectly in other webcam software using the pwc drivers. However, whenever I try and use it in PD, about once a second I get some black interference across the image for a few frames. When PDP initiates the device it says that it is set at 27 fps. There doesn't seem to be any way that I can alter this and I suspect that this is the root of the problem. PDP is supposed to have special options for pwc cameras such as mine but it seems to just override any fps/resolution settings I set when I load the pwc module. I found the message below in the archive from over a year ago from somebody apparently having the identical problem. Unfortunately it went unanswered. I'm using PD 038.4, PDP 0.13 on Slackware 10.1 (kernel 2.4.29) on x86. Thanks for any help! Andrew Copied message below: Hey, I am not sure where to file pdp related bugs, so I am reporting some issues I face to you. Maybe someone can help me out? System info: Debian Kernel 2.6 on x86 with pwc/pwcx modules enabled, pd0.37-1 tarball, latest pdp tarball from your website, Philips 740 webcam. I am basically new to pd. Problems: Using pdp_v4l connected to a xv sink, vl4 device open succeeds, but * with a framerate of 27(!)fps. * the captured input is rendered greyscale instead of in color and with extremely overloaded brightness level. * display gets interrupted by a 100ms black gap every second or so - guess thats related to the 27fps? I get this distortion/gap-jitter combination even with metro settings ranging from 10 to 300. After shutting down pd and opening the cam again with camstream I _still_ see the gaps, then by resetting cam-settings I get my cristal clear colored 25fps back. Consequently I disabled direct pwc-support in pdp and recompiled, without luck - pdp_v4l still seems to change pwc specific cam-settings. The PDP readme mentiones included "special" pwc-support. What does that mean/do? And how can I disable that except of the configure --disable-pwc option? The cam runs flawlessly in every other v4l compiant application on my system (camstream, gstreamer, mp4live). * sending a "close" message to pdp_v4l doesn't release it's device. * sending pdp_v4l a "type" msg yields a "no method for 'type'" warning and does basically nothing. Before I run to the next store to get me another cam, is there a way to resolve (at least) the image distortion and "black-gaps interruption"-sync issues? Or is there someone around doing reliable v4l-capturing and could give me some hints on how to setup. Best Regards, Thomas Comiotto -- -- Andrew Cavers andrew.cavers(a)gmail.com
