 Have you an exemple.

there is a blobtracker-example in Gem, which uses the [pix_blobtracker]
abstraction (consisting of [pix_multiblob] and some matrix magic to do
the tracking).

 Yes, debian packages!
 
 so what you suggest for a successfull pd installation on a ubuntu
 machine is to download this:
 http://autobuild.puredata.info/auto-build/latest/pd-2006-12-04-linux-debian-stable-i386-i686.tar.bz2
 
 
 and then run
 
 tar xjf pd-2006-12-04-linux-debian-stable-i386-i686.tar.bz2
 cd pd-2006-12-04-linux-debian-stable-i386-i686
 make install prefix=/usr/local
 
 and then it should run with Gem like
 ./pd -lib Gem
 
 ?

no. a .tgz build on a debian-machine is not a debian package.
a debian-package is a .deb file which holds the content of the tgz PLUS
some meta information (like dependencies!).
you manually install it via dpkg.
more often you (de)install it via apt-get, aptitude or synaptics.

reading your email again, i understand it better: the suggestion is not
to install the files tagged with debian on an ubuntu system but to use
a special packaging format, which by chance is used by both debian
(thats why it is called debian-package or .deb) and ubuntu (which is
really just a polished up debian clone).

building debian packages on the autobuild farm would eventually result
in having different packages for debian-stable, debian-testing,
ubuntu-hoary. (because of the very problem of dependencies)

i hope i could make this somewhat clearer.

it is not a tool to make the most stripped down version.

if you want configure to create a most generic package, then you will
have to pass arguments to it (e.g. --disable-NV)


 
 When building packages (.deb, .tar.gz, whatever), its much more
 important that it run on all machines, than its very well optimized on

this is correct, but as said above, configure is not necessarily the

externs is used by some people for legacy reasons. they add it

i am not sure whether i fully understand what you mean.

[pix_record] will _only_ record pixes. (e.g. you have to transform your
rectangles into pix-domain; just using [rectangle] won't do)

due to the signal-flow nature of pix-processing you have to add
[pix_record] after all pix-processing objects you want to have an effect
on the recorded video.

e.g.

[pix_video]

[pix_gain]
|
[pix_record]

[pix_invert]

will record a video with [pix_gain] applied, but [pix_invert] is NOT
applied.

[EMAIL PROTECTED] wrote:
 hello
 
 I've seen your message on the pd list about alpha mix of live input
 
 I'had got the same problem as you with the pix_mix box (vertical flip)

well, this is basically a problem of how the images are presented to Gem
by whichever source. some systems prefer to anchor an image at the
upper-right corner, others (like openGL) prefer to assume that (0/0) is
in the lower-right corner.
this makes images from one system appear upside down in the other.

luckily, Gem automatically takes care of this when it comes to texturing
(so you normally shouldn't notice).

however, when you want to combine 2 such sources, Gem uses the raw data
(for performance reasons), and ignores if one of the 2 images is flipped
upside down.

thats why you get weird effects in such cases.

how to cope with this:
1) don't use pix_objects for doing things you can do without (e.g. mixing)
2) recode the combining pix_objects to obey the upside down flags
3) flip on of the images via the [pix_flip] object

 
 It seems that gem prefers working in 3D than with pix_ objects ...

obivously, since this is what Gem is made for.
you can get a lot of performance from this.

 
 
 so
 I've made this box to mix two sources
 (the mix is in 3D however, it's not
 recordable with pix_record, but it's viewable)
 

it _is_ recordable via [pix_record]; use [pix_snap].

on os-x you will get this as an unwanted by-product.

[pix_film]/[pix_movie] to play back the images and [readsf~]/[tabplay~]
or whatever you want for sound.

this is really by purpose.
automated audio playback does not make so much sense in random
frame-access mode, without defining a lot of aesthetics for you.
it would make more sense for normal playback (like with [auto 1(), but
what if you would want time-stretched playback?

it would be good however, to have a way to read the sound-track of a

 digital camera (for photo) and a DVcamera (so with a firewire link). I'm not
 interested in having a huge resolution, 640x480 is the maximum (because I
 haven't got a very fast computer and I prefer to have lot of photographs (I
 hope there will be a lot of spectator !)). Is it possible to control theses
 devices with pd, or to create an external program (in a different language)
 which communicates with pd. Is there documentation about this ?

as for the digital (photo) camera:

to get the pictures into pd, you usually have to mount the device once
it is plugged into your pc, then you move the images to harddisk (which
is much faster) and unmount the device.
while you are moving the images to your harddisk, you would do the
rescaling.
since this is a rather complicated task, you would usually wrap this
into a script which has better access to the system than pd.
i would suggest a shell (bash) script (probably because i am better at
writing bash scripts than writing python code)

i guess a lot of people would use [shell] to control the bash script.
however i tend to rather use a simple daemon, which runs independently
of pd and checks for the camera and executes the script on demand.
when the copying is done, i would send the names of the new files to pd
via pdsend.
i prefer to not use [shell], because a) i usually don't have it
installed since it is an external, and b) because a separate daemon
would interfere less with pd's realtime thread.

but that is just my approach to such things.

cards for laptops will only provide openGL acceleration on the first
head. trying to render to the 2nd screen might be ignored by the driver.

the same problem should appear with any openGL application. e.g. if you
run glxgears and move the window to the 2nd head, rendering should
vanish too.
there is nothing you can do about this, but:
a) try to mirror the output of the built-in screen to the external
screen. this way you have less possibilities to interact with your patch
(since your primary display is occupied by the fullscreen gem window),
but at least you might get output.

b) buy another gfx card (the problem with laptops is, that this usually
means buying another laptop); nvidia chips are known to work well (but
are problematic license wise); i think others (frank) have managed to
get Gem rendering to a projector with intel chipsets.



ah and finally: you should not use fullscreen to make a fullscreen
window on the 2nd monitor when not in OS-X land (yet). use [offset 1024
0, dimen 800 600( (or whatever fits your settings) instead.

well it says that you have known problems with your gfx card.


 that type of card. I had managed to display clone and extended screen. But

this is what frank said: use clone; some (esp. older) gfx cards on
laptops will do this in hardware (no drivers involved);

you notice this, if you have a special key combination which you can use
to switch between the various settings, regardless of the os you are
running.

 under windows 2K (glups !) i can get an extended desktop and the video is
 rendered (for example, with VLC player) on the external screen. Maybe this
 because this is not OpenGL. In this case, couldn't it exist a trick to render

yes; obviously non-openGL calls are rendered to the 2nd head; else it
would be completely useless (always black ;-))
however, you should also be able to use vlc on linux on the 2nd screen.

 it as non-3D (wich doesn't interest me, i'm doing 2D with Gem, because i know

well Gem is 3d; you cannot do non-openGL stuff in Gem
(not totally true: the pix_ stuff is completely independent from openGL,
but whenever you want to display it (within Gem) you are bound to openGL)

 it better) or something like passing it from Gem to pdp ? If I remember well
 the workshop i did, there's something like gem_to_pdp... Or should I use pdp 
 in
 case of Gem ?

yes that is an option:
if you can stay within one library, i suggest to do so.
converting data between Gem and pdp costs you time; so if you don't
necessarily need a functionality that is only provided in Gem i would
try to do it in pdp alone.

however, afaik there _is_ one functionality that is only provided by
Gem: [pix_video] is able to capture your DV-camera; [pdp_ieee1394] is
(to my knowledge) only functional on os-x.
the bridging objects are called:
[gem2pdp] : convert the current rendering buffer of gem to a pdp-packet
[pdp2gem] : convert the current pdp-packet into a pix
[pix_2pdp]: convert the current pix into a pdp-packet


 
 About the Intel Graphics, I heard that Intel had just made their drivers more
 open, dont't they ? Do you think, there will be more support for these cards
 later with linux ?

i am not sure whether this is an issue with the (software) driver or
hardware.
you could try to run Gem on the 2nd screen under w32 (if you still have
it) and see what happens (and have a look at the cpu-meter, it might be
that your system switches to software rendering on the 2nd screen, which
still gives you an image, but at the cost of a rather high cpu load)

if it is a hardware problem, then nobody will be able to help you.

if you install pd differently (e.g. on debian with apt), you might get

i think no standard binary distribution of pd comes without this

 someone help me with it as I have no idea how to compile it myself.

obivously it is possible to compile Gem, sice the devs do so ;-)

compiling a _basic_ Gem is as simple as:
installing the xcode tools.
checkout Gem
open a console, cd Gem/src and do make
(running make will run aclocal, autoconf, ./configure and make)
this however, will still give you no text-support. (but at least you
have managed to compile Gem; this is a good start)

to add text support you need freetype2 and FTGL; the latter is part of
GemLibs.
to install freetype2 either get it from the web (afaik this is a
sourceforge probject) and compile+install it (according to the
documentation that comes with it)
the simpler way is, to install the freetype2 and freetype2-dev packages
via fink.
then compile and install FTGL (open the FTGL-project in
GemLibs/FTGL/mac, adapt to your paths and compile)


then run ./configure in Gem/src (after running aclocal and
autoconf once!), probably with some paths to point to your
FTGL-installation (see ./configure --help)

 I guess a list of object and there relation can be fetched by parsing

this i don't understand.

 likewise), hence the description of the object will need human
 interaction (after the parsing code has been written). But i might be
 all wrong.
 
 I've got a few questions:
 - Where (or why) did the project stall?

because the iem changed it's database infrastructure.

 - Was it made manually or fetched from the code in CVS?

it was done all manually.
in the beginning, one single person maintained the entire database.
in the end everybody was given (password protected) access, so they
could add their objects.

 - How does the term Library in this context relate to the terms External
 and Abstraction?

these terms in the pddb are historical and therefore not necessarily
appropriate.
back then, there were only libraries of externals (afair).



apart from that:
personally i am not convinced that the database should be created on the
fly from CVS for various reasons:
- code would have to follow a certain outline in order to make this work
- separation between code and documentation is rather low (coders
usually hate to documentate their stuff; so a host of volunteers is
needed to do the documentation; they don't necessarily need to interfere
with the source-code for this task)
- accuracy tends to be low with automated systems


so i think that the database ought to be manually maintained.
the existing pddb and the metadata in CVS would be used to initially
populate the database.



ideas:
everybody can add their objects to the pddb. and eventually delete them.
people not owning an object should not be able to delete it.

there should be a mechanism to reserve object-names, prior to
implementation. if the object is not implemented within a certain time,
the reservation expires.

a mechanism to reserve (and document) entire namespaces (not
necessarily directory-based namespaces!)

 I thought that the description was per object, hence not per group of
 externals. Fx. the metadata for zexy says swiss army knife for pd. I
 can't just find one, but there could well be a group of  externals with
 only one object, in which case the description of the group of externals
 would be the same as the for the that one object. So i most cases manual
 editing of descriptions would be needed especially if the description is
 to be per object.


hmm, i think i understand.
the pdb should hold both accurate descriptions of objects and generic
descriptions of libraries (if there is a library at all)
appearently swiss army kife for pd doesn't tell you anything about
[z~], which is probably what you are looking for.

 Ok. I thought that such outline was already established by m_pd.h or
 the way to write externals.

no, this won't help you.
there is no point in documenting that the object understands open
symbol messages, if you don't know what the object does.
i always thought that pdb is not a help-patch replacement but a place to
find an object that does certain things (like: being written by somebody
;-))

 Ok. I was just suggesting what i thought would be the easiest way to
 keep the database accuracy high, since, as you say, coders don't

 That's all.

i think we don't disagree here. i think most things i said are implicit

e.g. create a new patch (Ctrl-N), copy the channel-code in there, and
save it as channel.pd. now you can create objects [channel], each

of course you will have to parametrize your abstraction by use of

4. I concluded that something is wrong with ./configure. Indeed, I
confirmed
googling the web that the validation of existence of functions in
some configure
scripts is broken.

5. Found a suggestion on the web to the effect of re-generating
configure, using
autoconf.
These are the steps:
$ rm -f aclocal.m4
$ autoupdate
$ aclocal-1.4
$ autoconf
aclocal.m4:36: error: m4_defn: undefined macro: _m4_divert_diversion
autoconf/libs.m4:134: AC_CHECK_LIB is expanded from...
aclocal.m4:36: the top level
autom4te: /usr/bin/m4 failed with exit status: 1
That is, the autoconf data scripts are also broken, at least for
Fedora Core 5.

you need aclocal-1.8

6. went googling again for _m4_divert_diversion and got a bzillion
postings about
this, all discussing how screwed is the autoconf system that for its
continuing
evolution no two versions of one utility are compatible with any
other, or maybe
the same, version of another utility, that older scripts didn't
generate quotes,
and a bunch of other whatevers. That is the reason why it was
recommended
to use aclocal-1.4, an old version, rather than the current one,
named just
aclocal (v1.9). With all the talking about this, I did not find a
script-solution
that can fix old versions of autoconf scripts to bring them
up-to-date, to
be usable in FC5.

Perhaps there is such magic script, or some other way to migrate the
software
automatically to FC5 or FC6. Do you know of one?. Or how can I compile GEM
in FC5 in some other way?

yes!
get the CVS-version of Gem.
you will need _recent_ versions of aclocal and autoconf.
(and the build-process is started from src/ instead of src/Gnu/)
it should work like a charm...

Thank you for any help or hints.

TioP

PS. Of course it is expected that the solution found be compatible with the
Fedora Linux ways, i.e. wasting 1/2 day adjusting things, googling,
editing,
re-compiling, filling-in missing packages, finding left-and-right that
one package
needs another 4 or 5 new or updated packages, that in turn require me to
upgrade
X and C libraries, i.e. another 50 packages, which in turn require to
upgrade also
GNOME, Tcl/Tk, etc, etc, which in turn perhaps I better upgrade to
FC6, which
of course won't solve the problem either. And all this will make me
appreciate more
the wonderful life that we, the masochists that use Linux, are so used
to live.
May be it will take a little longer than 1/2 day. May be a day and a
half ... or a week?
or 2.

it should take no more than 1hour with a vanilla machine and a
reasonable package manager to have a running Gem binary.
this is the time i usually spend downloading just the directX-sdk from
microsoft on a reasonable fast connection, just to find out that i will
need to spend another hour to download another SDK.

apart from that, Gem is also included in the autobuild of pd which also
supports FC.
that's for the sadists, who prefer to have other people to the stuff.

 Hey there,
 
 I'm trying to use mp3cast~ with Icecast 1.

stupid me, but why are you using icecast-1 instead of icecast-2 ?

 
 I tried altering the password in the icecast.conf file (which is very 
 confusing and difficult on Debian) but it still doesn't like it. I wanted to 

what is the confusiion and difficulty in editing the configuration file
(in Debian as opposed to other systems)?
usually it is as simple as opening the file with a text-editor (and the
correct permissions).



 tell makepasswd what password I wanted (by default it just makes up random 
 passwords!) so I did this:

well, this is what makepasswd does by definition. it Generates true
random passwords by using the /dev/random feature of Linux

 
 $ echo apassword | makepasswd --verbose --crypt --clearfrom=-
 
 which seemed to work. I copied the encrypted version into my icecast.conf 
 file. I guess thats right?

i might be totally wrong here, but to my knowledge, icecast stores
passwords in plaintexts.

 
 In PD, can you send send messages in any particular order? If so, would it 

yes, you can send messages in any order.
but be aware that it depends on the objects you are sending messages too
whether the order is important.
e.g. sending hello and you to print will result in hello you,
whereas sending you and then hello, will result in you hello,
which is something different.

(ok, that was just a joke, but it is still true that it depends on the
object whether order matters or not)

 matter what order I sent the 'connect' and 'passwd' messages to mp3cast~?

i think(! without reading the code), that following is happening:
the passwd message stores the password in [mp3cast~] for later use.
when you send it the [connect( message, it will use the previously
stored password to connect to the server.
so in this case it is _very important_ that you first send the [passwd(
message and then send the [connect( message (else [mp3cast~] would try
to connect to the server with an empty/default password)

 Yes, I keep checking this. Another things I might try is playing with the

 might have to be the same as the hostname that clients give...

it might well be, that icecast only binds to the public interface (e.g.
eth0) and NOT to the loopback-device (lo, that's the one that reacts
on 127.0.0.1 or localhost).

you can debug this by trying to connect to icecast with telnet and the 2
ip's.

another option is, that /etc/hosts.(allow|deny) restrict access to the
loopback-devices.

 Hello all,



 
 I've just downloaded fluid~pd_darwin .rar file.  It contains two files:
 fluid~help.pd and fluid~.pd_darwin.
 
 What kind of file is the .pd Darwin?  Where should I put it?

it is a dynamically linked library for os-x (the kernel of os-x is
called darwin)

 
 What about the fluid help file?  Do I put it here?-- pd\doc\5.reference

according to your syntax of file-paths i assume that you are on windows.
it would be nice if you could make this explicit.
you will not be able to use a darwin binary on windows, you will need
the windows binary. it should be named something.dll (at least on
pd=0.40; i have _no_ idea which pd version you are running)

once you have the correct binary, put both the binary (or abstraction)
and the help-file into a path where pd will find it.

one _standard_ path for this is the extra/ folder.
but you can put it whereever you like as long as you add this path to
your private search paths in the File-Path... menu.

 
 I'm not sure where to put the help files because there is the reference
 folder but there are also many help files in the extra folder as well.
 What is the difference?

the reference section is for pd internals; the extra section is for
objects that are not compiled into pd (e.g. 3rd party modules).
you might find help-patches for externals in the reference section, but
this is only for legacy reasons (there was a time, when pd would find
help-patches only in the reference folder)

 hi IOhannes
 
 thank you for the fast reply. in the meantime i tried the binary from
 Pd-0.39.2-extended-test7-ubuntu-dapper-i386 and: it worked well.

which version of Gem is this?

 use ./configure --with-glversion=1.5
 or - even better - get drivers that provide header-files which match.
 
 hm... how can i make sure, that i have the correct headerfiles? as far
 as i can tell i didn't install new headerfiles manually. the fact, that
 the the binary from hcs' pd-extended works, makes me think, that the
 problem is specific to my system (wrong headers?). what do i need to do
 in order to make sure, that i the ./configure of gem looks at the
 correct headers, respectively that i only have the correct headers
 installed?


the problem is, that your packageing system installs headers which
conform to openGL-2.0 but your driver (this is: the binary library) doesn't.
this is a known issue with ati-drivers, but it appeared to happen with
mesaGL too in recent versions.
i am not sure whether this could be considered really a bug on the
driver (header) side, but i tend to think so.

i could of course create tests during the configure process that test
for each and every openGL function used by Gem whether it is really
supported by the driver. but this is like writing the headers yourself,
and i don't see a reason to do that (why are headers provided?)

i don't know of any other way to test these things at (configure or)
compile time, therefore i leave it to the user to decide.
(it is not that i haven't tried to find a generic way to check; but i
haven't found any working solution, so i did the configure-flag; thanks
to ico for the trigger)

some my advice is:
if you experience problems with unresolved openGL-symbols, try to lower
the maximum openGL-version manually via the --with-glversion argument
until Gem runs.


on the long run Gem will switch to glew (this has been around for years)
which might fix these problems.

 with my own compile i didn't try everything, but i tried some of the
 help-patches and i had troubles with [pix_texture] (resp. any file that
 contains [pix_texture] like pid_image.pd, pix_video.pd and pix_film.pd

so this means, that trivia like the red-square example did work?

Re: [PD] hot do you get a comma into a symbol?

however, it will not help rich in his problems, since the comma ha a
special meaning in pd (it separates 2 messages).
so [amixer -c 1 cset numid=5 26,2,32768( will be interpreted as 3
messages [amixer -c 1 cset numid=5 26(, [2( and [32768(, which is most
likely not what he wants.
what is needed is one symbol which holds commas.

this can be achieved in several ways, the most simple is probably
using zexy's [list2symbol] with a delimiter , which can be generated
with [makefilename %c] and a value 44.

like:

[26 2 32768(
|
[t list bang]
|   |
|   [44(
|   |
|   [makefilename %c]
|   |
[list2symbol]
|


you can acchieve the same with pure pd as well, but it gets more
complicated (and you might want pd=0.40 for better list handling)

(to be honest, i anticipated this problem; that is why i directed you to
the faq)



furthermore, if you do have problems with any software that is unrelated
to pd (e.g. proper inline quotes in emails) and you really want to ask
people here, then i suggest to use pd-ot, a mailing list dedicated to
off topic stuff.
(and yes, you should have been informed that such list exists, either
via the mail response when subscribing to pd-list or via the
webinterface where you did subscribe)


that said, i hope i do not sound too rude and wish you good luck (sic!).

i am not sure whether sourceforge forbids to put a code that is licensed

apart from that, the license does not forbid to put it into any open

so imo, the license allows us to include it on sourceforge, but

one solution would be, to not use the stack at all, if it is possible.
in your case, this is fairly easy (see attached patch).

 Hi and thanks for your help so far.
 
 In my previous message my abstraction was too simple.  I can't use
 [Until] after all.

the problem is the same and it can be resolved with [until].
see attached patch.

 
 You can see by the attached patch the behavior that I want using
 [textfile].   I want to output records until I find a wait, wait a bit,
 then continue.  This works fine with textfile.  However, I also want to
 be able to seek a certain record without causing any output.  That is
 why I thought I could use [msgfile]'s goto message.   Unfortunately,
 [msgfile] doesn't work at all for the basic process.

a fixed version of msgfile is now available in CVS.

even though the fixed msgfile now allows you to do your stuff in a
recursive way, i strongly suggest using an [until] based approach.

i don't think that you can just skip the parameters that you are not

like: obj 50 100 tgl 5 0 none none none 0 0 0 0 0 1
2 0 0

if you are unsure, it is always a good idea to just save the gui object

however, this does not mean, that specifying one parameter will give you

 btw. stupid newbie question: how can i access /dev/tty without starting

use the permission system to aquire permissions ;-)

this is: make sure that there is a group that can access the device

make sure that your user belongs to this group.


like:
% chgrp ttygroup /dev/rfcomm1
% chmod g+rw /dev/tty
% adduser username ttygroup

(you will have to do this as root; and you will have to re-login as user

 I think that they are not as big as you'd guess because there are  
 international treaties that are all about making these laws work in  
 the same ways across borders.  Copyright, patents, and trademarks act  
 quite similarly in all countries that participate in these treaties  
 (which is most).

not quite true.
(i'd say it is an anglo-centristic viewpoint ;-))
after all, in anglo-american space we have to deal with copyright
whereas in continental europe we still have the urheberrecht which is
something really different.



 things are certainly better in CreativeCommons (among other things
 because they are less u.s.-centric than the FSF).
 
 Hmm, that's debatable.  They don't have a license without an  
 attribution clause, it's not even an option. And the CC attribution  
 clause is much worse than the BSD attribution clause ever was.

yes i agree here.
i was just trying to say that the creative commons is much more
court-proof in different countries since it has been adapted to really
fit within the legislature of these.

the GPL never had anything but the u.s.-american copyright law in mind,
which makes it not necesserarily fit for other countries.
i do not say that the GPL is bad or futile in europe, it is the license
i use...
