 Hi all,

 This card works (audio i/o) with the Raspberry PI (Raspbian).

 You just need to type 'amixer -c 1 set Mic 80% cap' in a term window to
 enable to Mic.  In PD, under preferences, choose 'Alsa' as output and
 under 'audio configuration', select 'input Generic AudioUSB Device

Re: [PD] Mix two video streams and add DSK

2010-10-03 Thread Alexandre Castonguay

 Hi Jamie,


The only experience I had with 2 simultaneous live feeds was with 
Hauppage PCI cards (analog signal in @ 640 x 480).   Otherwise, DV input 
works in GEM but I only had one available port.  With multiple live 
feeds or heavy video manipulation, you have to expect decreased image 
quality and latency, how much of it depends on your budget. It would be 
cool to benchmark what the best speed/resolution available would be once 
you build it.


Another solution is for the users to realize that there is intrinsic 
value in latency and glitches (both aesthetic and political) and find a 
way to somehow incorporate it in the work.  There is a good text on this 
by one of the recent subscribers to the list.


Cheers,

Alexandre

Thanks Alexandre and Simon,


It sounds like technically the task is a trivial one, thanks for the tips.

In terms of latency, I get the impression this is a function of the video 
capture method used...

@Simon, can you tell me which PCI card you are using?

This project is to port a piece originally done with Max/Jitter to a Pd-based 
system. The main complaints they had were video quality and latency, so those 
are problems we need to solve.

All best,

Jamie

Is this possible with Gem? Gridflow?

If this is indeed possible, what sort of latency could I achieve from input to

Any advice appreciated.

Re: [PD] a really fast-to-read codec in linux?

 Hi,

Did you try photo jpeg?

Best of luck,

Alexandre

Le 10-09-24 05:34, Matteo Sisti Sette a écrit :

Hi,

I'm desperately looking for a codec to code video files with so that 
pix_film will be able to read them with the best performance. I don't 
care if the compression rate is very low, as long as the quality is 
good and reading is fast.


Does anybody know any?

Mjpeg seems to perform quite well, but not well enough. Maybe that's 
the best performance I can expect and I have to reduce the video 
resolution but I would like to be sure.


H.264 has the problem that has been mentioned due to an issue of 
gstream with frame seeking that makes it terribly slow in linux.


I'm trying all the codecs I see listed in avidemux, but there are so 
many and with so many configuration settings that I don't quite 
understand, and many of them just make Pd crash.



By the way I would also like to know the answer to the same question 
in Mac. As far as I have seen, though, video with GEM seems to perform 
always much worst in Mac than in Windows and Linux with any codec 
(except h264 that has a big issue in linux only) - Mathieu said he 
probably knew the cause of this which was not related to codecs.

It's been a while since I've posted, I hope everyone is keeping well!
I'm trying to retrieve data from a heart rate monitor with Pd using
the comport object. Sending a 'G1' followed by a carriage return to
the HRM device using a terminal emulator returns something like 32 10
61, where 61 is the current heart rate and 10 is the time passed since
I first queried the heart rate. If I try to print this info in Pd ala:

|comport|

|sprintf %c|

|print|

I get something like this:

3
2
1
0
6
1

Obviously this isn't much use to me. The data that is passed from the
serial device is an 8 bit value but I've no idea how to parse it
correctly. If I don't use sprintf I get the following print out:

print: 51
print: 32
print: 49
print: 48
print: 50
print: 32
print: 48

Any ideas or suggestions on how to parse the data being returned from

My guess:
Trigger sequences the messages one after the other, but still within one
event, or timeframe...or what's the name...
So I think in your patch the 'clear' message and '42' arrive simultaneously.
If you put a [del] object inbetween the trigger object and the 'clear'
message it works,
(see attachment) but that's surely not the right way to do these things.
I also wonder what you would need this for.

[PD] arduino-test.pd crashes windows vista

Hi Hans,

I am helping someone with Pduino and opening arduino-test.pd crashes PD.  The 
[arduino] abstraction opens fine and so does arduino-help.pd.  The patch opens

arduino 0018

useful report.

Re: [PD] Can I control the velocity of a video?

2010-02-09 Thread Alexandre Castonguay

Hi,

Use [pix_film] with a [counter] and vary the speed of the [metro] going 
to the counter.  I think you will need to send the 'auto 0' message to 
[pix_film].  There is also an object named [gems.movies~] in the pdmtl 
abstractions package.  All these objects have good help patches 
detailing their workings.


Good luck,

Alexandre

Re: [PD] life as a new media artist

2009-11-04 Thread Alexandre Castonguay
The question reminds me of : Letters to a Young Artist, a collection of 
essays modeled after Goethe's letter (another good read).  It has some 
insights from people like Adrian Piper,  William Pole L. and the 
Guerilla Girls.  The variables are alike between the artistic discipline 
(time, revenues, integrity) but there are a couple of important 
variations for media art. Nearly 80% of all art purchases are paintings 
so making a living may mean teaching or finding other employement within 
the field.  Another important distinction is gender. The media arts 
field, especially the more technical aspects of it, is dominated by 
males.  It can lead to a culture shock sometimes but I don't know 
whether gender has a positive or negative effect on gaining most of your 
revenues in the field.  Where you find your training is also a 
determinant and the answer to the question of survival as a media artist 
will depend on where you want to be based. Support for culture, public 
or private, varies so much from one state to another.  Be mindful of the 
tools, PD is one of the tools that will shape your practice the least. I 
like Natalie Jeremijenko's take on technology (not her exact words) : 
artist's are good at making dumb things out of expensive technology and 
making smart things out of obsolete tech.


My advice would be to just work. Don't spend too much time networking 
and worrying about a career, if the work is not there, nothing will 
happen. Devote all your energies to it and if the sleep deprivation (and 
bills) catch up to you and the motivation isn't there any longer, then 
you can take all that you will have learned and find another path.  It 
should be easier than surviving as a media artist. I don't want to sound 
dire, I feel priviledged to be able to keep making art and it's amazing 
to be able to teach it.  What I mean to say is that if you need to be an 
artist then you will find a way to support your practice.

Good luck,

Alexandre

Re: [PD] extrenal video card to capture video

2009-10-21 Thread Alexandre Castonguay
I get good results with hauppage wintv cards + linux.  You can find them
used for cheap.  Support for dv input depends on the platform you are on.

If you just need camera input, you can use usb cams.  Most of them are
supported, I use logitech cameras a lot.  Macam is the driver on a mac.

Bonne chance,

Hi Hans,

I'm pleased to report that it is starting to work on the Mega.  I can

http://at.or.at/hans/pd/objects.html#pduino

There are some nice updates to Firmata and Pduino.  This release
mostly adds extensions to the protocol to support more pin modes
and their respective messages (Servo, I2C, Shift Registers, etc).
 Here are some specifics:

- Servo support for StandardFirmata
- support for using analog pins as digital I/Os for StandardFirmata
- new message to set the poll rate of StandardFirmata
- I2C Firmata example (needs Pd implementation)
- switch back to 57600 for standard bitrate
- made Firmata.begin(57600) explicit in all examples

Please test and report and bugs or issues.  We are trying to get
this included in the upcoming Arduino 0017 release.  Depending on
the 0017 release schedule, we might be able to squeeze in Shift
Register/Matrix support too.  Also, just to note, this update
includes code from (in alphabetical order):

Re: [PD] PD t-shirts

2009-03-31 Thread Alexandre Castonguay
Hi Ben, all,

We did the last batch of t's as a fundraiser for the Convention in
Montréal.  We managed to pay for another 1/2 plane ticket with the
proceeds :-).  Maybe the same could be done for São Paulo?

The super folks from Graz sent the file they used for the original t's I
should still have it if you want.

À bientôt,

Alexandre



 Hello List,

 I'm considering designing and selling PD related t-shirts.  I haven't
 totally worked out the logistics.  Basically I was inspired by the
 [Bang( shirts that I've seen online, but which are no longer available
 as far as I can tell.

 Anyway, if I did so, I would like to donate all of the proceeds toward
 further PD development, specifically documentation of poorly
 documented objects (or example patches, which is basically the same
 thing).

 How do you all think would be the best way of going about this?

 Should I stockpile the money and then offer it to someone as a sort of
 grant?  That's less than ideal in my opinion.  I really don't know how
 to go about this.

 Any/all input is welcome

 -Ben

Re: [PD] Camera into linux Linux

2008-06-07 Thread Alexandre Castonguay
Hiya,

Could you test with xawtv to see if you get video from the card?  The blue 
screen is output by the card if there is no video input going into it so 
maybe the problem is with the camera?  Or do you want tv input into it?
Again, live troubleshooting for something like this so try the irc channel.

Cheers,

Hi all,

Some ruby still exists for code generation but you don't need the ruby headers 
anymore.  

Live camera input doesn't work yet but you can play videos.  Playing videos is 
about 2x faster on OSX than linux but the rest is noticeably slower. The

hidecursor).  Many of these issues should be solved by next week but any help

 grab the latest sources and then do ./configure --no-mpeg3.
 after that add the path to your pd sources to the CFLAGS in config.make.
 mine is -I/Users/marius/devel/pd-rsync/pd-extended/pd/src and set
 -mtune=k8 -march=k8 if you have an intel mac.
 then it should compile and run. have not tested all objects, some seem

Re: [PD] [OT] Re: about sexism is TERMINATE THREAD PLEASE

2007-10-21 Thread Alexandre Castonguay
Hi all, Yves,

Here are some facts may help explain and paint a correct picture of the
convention's gender distribution.

Number of applications received for the exhibition component :

9 (F)
26 (M)

Invitations sent :

6 (F)
12 (M)

Number of applications for performances (* I am unsure as to the gender of
one applicant as we didn't ask people to specify it in their application.)

3 (F)
32 (M)

Invitations sent :

2 (F)
18 (M)

As Andrew Brouse noted, the applications for papers did not carry the
author's names so it makes it hard to get a picture of the gender
breakdown. Out of 46 'papers invitations', 2 were extended to women and I
believe that may unfortunately be the number of applicants?  Andrew may be
able to answer to that.

I believe that the impression Yves got is justified.  It is just that the
community is overwhelmingly male and 'white' (another thread!).  It also
seems that the juries for the papers, exhibition and performances were
conscious of the fact as it is somewhat reflected in the final breakdown
of invitations sent.

Some observations on other parts of this long thread that may yet yield
something positive.

* The component of the convention that had the highest representation of
women applicants was the exhibition. It shows that this form of
contribution is often the way through which women enter the community. It
should be maintained and expanded through other conventions.

* I heard through the application process that some women were intimidated
by the perceived technological sophistication of the pd scene and thought
that their work may not be 'pure' enough to warrant an application. In
that light, dismissing people whose work process calls on external
expertise to be realized does not help with that perception of purity.

* I am personally glad that our efforts of providing better documentation
and access to the software got a renewed push through the work groups and
discussions happening at the convention.

* Building a more representative community will take time and many more
pd-conventions, workshops, efforts through documentation and packaging,
participating in long email threads and chats.  Let's keep in mind that
most of us take part in these efforts because we believe we can make the
community more inclusive, make good work and have fun while doing it.

A bientot,

Alexandre

 I don't understand how to make categorie in wikipedia...

 I think, the first step is to complete pd-vanilla. After we can try to
 organize it into more sensitiv categorie.

 The search engine seems hard to use, but may be someone work on it. It's
 quite hard to find objects ...

Hi all, Thomas,

Thank you all for your feedback and participation, we had a great time and
I miss having so much to see + learn everyday (and night).

I think there is a lot of merit in suggestions of using pd (or other open
source tools) to facilitate the communications between us.  We had some
discussions on how to better use existing tools for online communication
(documentation, workshops, etc). We can count on a very friendly network
of individuals, user groups and centres that could support smaller
initiatives.
But the combination of performances, exhibitions and talks + all the
exchanges that proceed from them make an actual large pd-convention
difficult to replace in my view.

A couple questions I had relates to timing : how often and what is the
best time of the year to hold a convention?

Conventions have a motivating effect and foster understanding and cohesion
(one hopes).  Three years is a long span and every year would be too
taxing I believe.

It's difficult to accommodate everyone's schedules and we chose the end of
August partly because we knew a number of people who teach or study could
travel then. It also meant that a lot of the spaces we needed were
available (thanks to the centres!). However, it could have been easier to
involve students if the semester had started.

Finally, other nice recurring events like Piksel, Make Art, the Linux
Audio Conference and the ICMC (sorry for the squeeze) etc. are to be
worked around.  It's all a little premature at this point but what are
your thoughts on timing a convention?

A bientot,

Alexandre




 Hey all,
 here are my sincere thanks to all the people who made the convention
 possible. It was a great time, although much too short!
 I hope to meet again some of you in the next future!

[PD] small(est) hardware solution(s)

2007-07-26 Thread Alexandre Castonguay
Hello Marius, list,

If you only need a few seconds (10-20), you can use the ISD1110 or
ISD1420PI-ND (available at digikey.com).

Here's a schematic of it from Diana Burgoyne that made 'diagram of the
day' on #dataflow :

[PD] pd-extended on kubuntu/feisty

2007-06-07 Thread Alexandre Castonguay
Hello all, Hans-Christoph,

I was trying to compile pd-extended on kubuntu/feisty from the cvs today and 
stumbled on a few problems :

cd /home/alx/pd/pure-data/externals/iem16/src  autoconf
configure.ac:40: error: possibly undefined macro: AC_CHECK_CFLAGS
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:156: error: possibly undefined macro: AC_CHECK_LDFLAGS

It worked after downgrading automake to 1.9 from 1.10...but now I'm stuck 
here :

/home/alx/pd/pure-data/externals/build/src/../../zexy/src/zexy.h:47:23: error: 
zexyconf.h: No such file or directory
make[2]: *** [/home/alx/pd/pure-data/externals/build/src/any2list.o] Error 1

I'm doing this to try [hid] or [hidio] since I just got the usb retropad for 
the nes.  I hope NIME is a lot of fun.
 
Cheers,

Alexandre

Hi all, hc,

Switching autoconf 1.10 for 1.9 and getting zexyconf.h did the trick, the 
install went well after that.

My Nintendo NES controller (+RetroPad) works with hidio, now I need a rom 
emulator in pd ;-).

Cheers,

Alexandre

 Well the easiest way to build [hid] would be to do this:

 cd externals
 make hid

 Otherwise, I think zexyconf.h is in CVS, and zexy won't build
 properly after a make clean, so try a cvs up to get zexyconf.h
 back.  Beyond that I don't really know since IOhannes replaced my Pd-
 extended build stuff for zexy with his own.

Re: [PD] pixel analyse _ gridflow undefined symbol

   Hi list,
   I'd like to know if there is an object or an abstration to output the

   gridflow ? Any ideas/hints would be welcome.
   cheers

  The extraction is easy with GridFlow (for example, [#export_list]), and
  the 3D could be done with Gem.

open some_image.jpg - [#in] - [#rgb_to_greyscale] - [#export_list] - 
[print]

 
  Hi.  I'm not having any luck finding GridFlow, or any documentation.
  I found a few dead links... anyone have a live one?

http://gridflow.ca/  (the server was down yesterday for a few hours)

  -Chuckk

 Thank you for the answer, i'll try each of the solution to see which one
 fits best my needs. By experience will one of them be faster and more
 stable?
 By the way I compiled gridflow from cvs , but I can't load it:

 ./gridflow.pd_linux: ./gridflow.pd_linux: undefined symbol:
 _ZN9CPPExtern10m_holdnameE
 gridflow: can't load library

 I've tried with gcc4.1 and 3.4, on an ubuntu32 system. Sould I use the
 8.4 release instead of the CVS one or am I missing something ( config is
 fine and find everything it needs) ...

I'm running the latest cvs on such a system and everything look ok.  Maybe we 
can troubleshoot your installation on #dataflow (irc.freenode.net)?

Cheers,

Alexandre
