Re: [PD] Is it possible to change webcam's resolution in Mac OS?

[Max]

I'm guessing this is a colorspace issue. try [pix_rgba] right after [pix_video].

[Marian Weger]

- Does the "dimen" message work on Mac OS? (it doesn't on Linux, at 
least with my hardware)


dimen works perfect for me on OSX 10.7 with PD 0.43 and Gem 0.93

[PD] new disis_wiimote : undefined symbol: sys_flushtogui

[Benjah @ 01xy.fr]

Hello,

while trying to compile the new disis_wiimote with the L2Ork version of 
CWiid library on ubuntu 10.04 against Pd extended 0.42.5 or Pd 0.43.2, I 
get "disis_wiimote.pd_linux: undefined symbol: sys_flushtogui" when 
trying to load the help patch disis_wiimote-help.pd and the object is 
not created.

Any idea why ?

thanks
Benjamin

Re: [PD] old patch to (automatically) fragment an audio buffer

[William Brent]

See 06-timbre-ordering/order.pd in the timbreID examples.  That one
rearranged grains of a fixed size.  order-perc.pd in the same
directory does it with a bunch of percussion sounds of various length.

[PD] Is it possible to change webcam's resolution in Mac OS?

[Matteo Sisti Sette]

Hi,

I'm using Pd Extended 0.42.5 and for a series of reasons upgrading is 
not an option right now. I don't have a Mac but I need my patches to 
work on Mac OS and Windows. (I can test windows and linux)


I don't know if it has been fixed in later versions of GEM, but there's 
some dreadful bug somewhere in [pix_video], [pix_movement] or [pix_blob] 
or maybe somewhere else, that causes [pix_blob] to randomly output 
out-of-range values for x and y (negative values and values a lot 
greater than 1), both on Windows and Mac.


On Windows a workaround that works is to lower the webcam's frame rate 
AND resolution (I'm not 100% sure the framerate is needed, but the 
resolution certainly is). I can live (unhappy) with having to do it 
manually every time, and I can trigger the settings dialog to open by 
sending the "dialog format" message to [pix_video] (unfortunately the 
values are not saved)


THE PROBLEM is that on Mac OS, the settings dialog that open up with 
"dialog format" doesn't give any option to change the resolution. I can 
change the framerate (which is not enough for the workaround to work) 
but not the resolution.


The questions then are:
- Is there a way, perhaps somewhere in the system settings in Mac OS, to 
lower the webcam's resolution?
- Does the "dimen" message work on Mac OS? (it doesn't on Linux, at 
least with my hardware)
- Btw Is there a message for setting the camera's framerate? (I don't 
find it documented)



And if anybody has encountered a similar issues 
(pix_video+pix_movement+pix_blob = out of range values) I'd of course 
love to know how you have worked around it (or is it worked it around?)



Thanks in advance
cheers
m.

Re: [PD] pduino patch help

[olsen]

Ej Drake

you've to put the arduino.pd abstraction and all other patches you're refering within the same folder where you saved 
your patch. Another problemo is your patch is refering to [arduino] and [Arduino] - notice the upper and the lower case 
- guess it should be lowercase [arduino] only! the argument within the [arduino] in your case f.e. [arduino 1] is the 
port that will be opened by loading the patch. You can get the info aboutthe availiable ports by sending a [devices( 
message to the [arduino] and/or reading the arduino-help.pd.

Date: 7th-8th September, 2012
Venue: ICSRiM, School of Music, University of Leeds, UK

CALL FOR PAPERS AND PERFORMANCES

Live Interfaces is a conference on live, technology-mediated
interaction in performance.  The conference seeks to investigate
cross-disciplinary understandings of performance technology with a
particular focus on issues related to the notion of ‘liveness’ in
interaction.

Live Interfaces will consist of paper and poster presentations,
performances and workshops over two days.   Researchers, theorists and
artists from diverse fields are encouraged to participate, including:
digital performance, live art, computer music, choreography, music
psychology, interaction design, human computer interaction, digital
aesthetics, computer vision, smart materials and augmented stage
technology.

We invite submissions addressing the conference theme of
technology-mediated live interaction  in performance, and suggest the
following indicative topics:

- Audience perception/interaction
- Biophysical sensors
- Brain-computer interfaces
- Computer vision/real-time video in performance
- Cross-modal perception/illusion
- Digital dramaturgy/choreography/composition
- Digital performance phenomenology
- Gesture recognition and control
- Historical perspectives
- Live coding in music, video animation and/or dance
- Participatory performance
- Performance technology aesthetics
- Redefining audience interaction
- Tangible interaction

Paper submissions should be in extended abstract form, with a
suggested length of 500 words.  Please format all submissions using
either the Word or LaTeX template available from the website.

Performance proposals should include a description of the performance
and the live interaction technology used, as well as a list of
technical requirements.  Attaching recordings of past performances is
strongly encouraged.

We hope to announce a journal special issue on performance technology
following the conference as a publication opportunity for extended
papers.

Extended abstracts must be submitted electronically via the website by
midnight (GMT+1) on the 17th June 2012.  All submissions will be
subject to cross-disciplinary peer review, and notified of acceptance
by 1st July.

Please address all queries to liveinterfa...@icsrim.org.uk

Key dates:

- 6th May - Call for extended abstracts
- 17th May - Submissions system open
- 17th June - Submission deadline
- 1st July - Notification of selected papers/performances
- 29th July - Camera-ready deadline for accepted papers
- 7-8th September - Conference

Registration will open nearer the date, with a fee in the region of
£25, including lunch for both days.

Re: [PD] old patch to (automatically) fragment an audio buffer

[William Brent]

The [bark] object in the latest timbreID analyzes samples loaded to
tables in non real time and reports the onset times.  If you're going
to make a new patch, it'll probably make the process of finding onsets
easier.  In the help file, after you hit the "analyze" button you can
play back any segment in the [pd segmented-player] subpatch.  You can
expand on it from there to do whatever you're after.

Re: [PD] [Pd] Compile external with C++ compiler?

Yep, this is what I'm doing. The issue is that to call C++ code in the C
external I need to compile it with a C++ compile, therefore I change the
source code extension to .mm (objective-c++). Now when I do this Xcode goes
all weird about class_addmethod(), which is maybe a namespace issue - I'm
not sure. But it means I can't add any methods in the external.

The solution I used was to write a C wrapper for the C++ library, it's a
bit annoying as any function I want to use has to be declared in the
wrapper, but it works so I can't complain. Maybe your dev guy might have a
solution? :)

Glad to see others using Pd on iOS/Android!

Cheers,
Joe
