Webcam not working in Gridflow on Ubuntu
by Stefan Donchev 28 Aug '11

28 Aug '11

I'm trying to get my webcam working in Gridflow 9.12 under Ubuntu 11.4. It works with GEM, not with Gridflow. GEM gives the following output in the Pd window when I open pix_video: [pix_video]: video driver 0: video4linux2 v4l2 [pix_video]: video driver 1: video4linux v4l [pix_video]: video driver 2: ieee1394 dv4l dv When I open the #camera help patch, I get the following output in the Pd window: print: symbol sdl error: constructor: ioctl VIDIOCGCAP: Invalid argument error: constructor: ioctl VIDIOCGPICT: Invalid argument camera supports palettes : error: _0_size: ioctl VIDIOCGWIN: Invalid argument error: _0_size: ioctl VIDIOCSWIN: Invalid argument error: _0_size: ioctl VIDIOCGWIN: Invalid argument error: _0_colorspace: ioctl VIDIOCGPICT: Invalid argument request use of palette 15 error: _0_colorspace: ioctl VIDIOCSPICT: Invalid argument error: _0_colorspace: ioctl VIDIOCGPICT: Invalid argument print: symbol videodev error: contrast: ioctl VIDIOCGPICT: Invalid argument error: colour: ioctl VIDIOCGPICT: Invalid argument error: brightness: ioctl VIDIOCGPICT: Invalid argument error: hue: ioctl VIDIOCGPICT: Invalid argument error: whiteness: ioctl VIDIOCGPICT: Invalid argument error: _0_size: ioctl VIDIOCGWIN: Invalid argument error: _0_size: ioctl VIDIOCSWIN: Invalid argument error: _0_size: ioctl VIDIOCGWIN: Invalid argument error: _0_size: ioctl VIDIOCGWIN: Invalid argument error: _0_size: ioctl VIDIOCSWIN: Invalid argument error: _0_size: ioctl VIDIOCGWIN: Invalid argument Changing the settings for #camera does not help. Does anyone have any suggestions what could keep the camera from working with Gridflow when it does work with GEM in the same installation of Pd? Ste

Desktop Screen Capture
by Andreas Eberharter 28 Aug '11

28 Aug '11

Hi all, I would like to create a patch, which allows the capture of the desktop screen and at the same time the iSight camera. If you are familiar with Silverpack http://silverbackapp.com/ it is basically, what I would like to achieve with pd/gem. I am just starting, so if this question was asked already once, please point me to the right direction (I used the search on the archives, but could not find what I was searching for) I am on a MacBook Pro running OS X 10.7. I have played with the examples and capturing video from the iSight camera works really nice, what I can't find though, is a screen capture option. Is this possible? Thank you for your help, Greetings, Andreas

[PD-announce] Pd-Convention: Recording 14th August
by pd.berlin 28 Aug '11

28 Aug '11

Hello everyone, the recording of the final improvisation night, 14th August, is already online on Michael's space - http://pdcon11.sinespine.org/final-impro-audio/. I left it untreated, in flac format. The recording is a stereo mix of the mixer's output. I think whoever played will recognise itself there. Best regards, João Pais _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Segmentation fault Gem 0.93 pix_delay, pix_motionblur, pix_colormatrix, pix_frei0r
by ALAN BROOKER 27 Aug '11

27 Aug '11

Hi, Kubuntu (Maverick) linux, PD 0.43 with new Gem 0.93 Im having issues with the pix objects that I believe specifically relate to video files ( such as pix_delay, pix_motionblur, pix_colormatrix, pix_frei0r) I can create the objects in the canvas, but when I click to open a help file, PD crashes and I get the message below in the terminal load plugins 'film' in '/home/alanb/pd-externals/Gem/' pattern : /home/alanb/pd-externals/Gem/gem_film*.so dylib loading file '/home/alanb/pd-externals/Gem/gem_filmMPEG3.so'! dylib loading file '/home/alanb/pd-externals/Gem/gem_filmQT4L.so'! Segmentation fault The Gem help patches that relate to pics such as jpg etc are fine. [pix_movie] and [pix_film] help patches come up but the auto play doesn't not work- using a number box to move the frames works however (if is was to send a metro then it would play fine) but not the auto play. Have these issues been replicated with anyone else or any advice to resolve ? Thanks all -appreciate any comments and the continued hard work on Gem & Pd. Al

by Фывапр Олджэвич 27 Aug '11

27 Aug '11

Hello ! Can anybody help to find exhaustive reference for programming messages in PD ? For example, I know how to let PD to create file and open new canvas - it is by this message: [ ; pd filename mon-nouveau-patch.pd /tmp; #N canvas; #X pop 1; ( And how, for example, to load some abstractions or new objects into existing patch on the fly ? I tried this : [ ; pd load myabstraction.pd ( and others... but its not working.. i tried to find in help and tutorials - can't ... is there any info about further programming messages ? thank you !
