Hanging as in not responding, but not quitting.  I guess bang/until

The advantage of this using PyPd for the unittest scripts is that PyPd

whether PyPd has the same goal in terms of monitoring the pd process.   
I can't see why not, but I suppose there could be a reason.

[PD] video formats to perform on PD (Gem or pd-gpg)

[Blinge]

Hi there!

I have just looking for a solution so much time but i didnt found a 
really good performance for my video-play on pd.


I've got so many videos from my own library ready to play on resolume on 
diferent formats. Now i want to set some (maybe all) of them to use my 
own pd patch.


I think the best performance video format to use on pd is "quicktime 
still frames" My doubt is: Is that correct? Or is there any other option 
for me to test?


I think Gem has 'a little' more possibilities than gpg. Isnt it? And in 
that case... Which are the best performance formats to run by Gem?


So if some of u can give me a little advice about file conversions on 
linux (to get best performance on pd) i would be glad to thank you for 
ur great help!


My usual OS now is an Ubuntu Karmic (9.10)

My source formats now are:

IV50 (my old video-libary)

raw DV format (captured directly from my dv-camera)

mp4 (captured in streets at day with my mobile phone camera)

And so many others that are not so important.

Thank u all for reading and have a nice day!

Blinge.

Googling some more makes me believe, that 'interleaved' does mean
nothing more than just 'many audio channels interleaved into one single
file'. So actually both my 8-channel WAV-files are interleaved. Both are
8ch 16bit 44100Hz PCM files and still they are different in that only
one of them is read correctly by [readanysf~]. 

* How can i get info about PCM-WAV files in Pd?
* How can i reliably play them back (with the ability to seek)?

[PD] [readanysf~] and so called interleaved wav files.

[Roman Haefeli]

Hi all

I'm trying to build an application that supports loading as many
different WAV-formats as possible (primarily different bit-depths and
number of channels). I found, that when focussing on PCM-encoded files
only, the variety of formats is still big. Actually, i'd like the
application to auto-recognize the number of channels of loaded files.
Since [readanysf~] doesn't do that, i use also [ext13/wavinfo] to gather
some data about the files. Unfortunately, this externals doesn't read
files with a so-called 'broadcast' format. But this is a different
story. 
Then i encountered, that there is something called 'interleaved' format.
Those multi-channel files are read fine by [readsf~], but not by
[readanysf~]. I have a 8-channel-interleaved file, which [readanysf~]
seems to play (according to the right most outlet), but all output
channels are mute. However, 8-channel-files i created myself, seem to
work well with both, [readsf~] and [readanysf~]. I have another
6-channel interleaved files, which only 5 are played from by
[readanysf~]. 
Now, i wonder what is the magic behind those 'interleaved' files and
also, if there is a way to play them in Pd _AND_ have a 'seek' option as
[readanysf~] offers?

if you want to use it from python just take scripts.py it has some

it from PD you need all the files, scr.py and search.py just wrap 
scripts.py with pyext classes, in this case check script_examples.pd . 
There is some other utilities in the library, check the readme file for

not sure whether i fully understand.
you will need to find the headers (m_pd.h; cwiid.h) and the libraries
(libcwiid.so)

is it possible to properly install libcwiid "properly" (make install)?

it's not "I" but "-I"
the compiler takes arguments like "-I/path/to/more/headers" to add more
search paths for include files (the linker uses "-L/path/to/more/libraries")

so the makefile often looks like:
PD_PATH=/opt/sw/pure-data/pd
CFLAGS="-I$(PD_PATH)/src"

(which will expand to the CompilerFLAGS "-I/opt/sw/pure-data/pd/src",
effectively adding the path to the directories searched for e.g. "m_pd.h")

if the m_pd.h in /usr/include and /opt/... is the same and the cwiid.h
in /usr/local/... and /opt/... are the same, you shouldn't need to set
any special paths.


well, this doesn't help you much since i'm saying that everything should
work but it doesn't...but you really should use an svn version of
libcwiid: http://abstrakraft.org/cwiid/svn/trunk)
attached is a patch against cwiid (rev201) that adds multiresolution
MotionPlus data.
in this case i also created a Make.local (for the external), containing

PD_INCLUDE += -DHAVE_CWIID_MOTIONPLUS_LOWSPEED

Hi All,

I finally packaged up some code I've had lying around for a while and added it
to PdParser to make PyPd - classes for interfacing with Pd from inside Python.

You can use Pd.py to launch Pd as a subprocess and communicate with it via
sockets. You can use PdParser.py to parse .pd files.



I started these classes quite a while ago, but their ongoing development is

Re: [PD] Motion Plus Data to be used with Puredata/OSC-Data-stream

[Luigi Rensinghoff]

Hi Florian, Johannes an Mike

   after a little abstinence period i want to come back to my  
wiimote experiments and would like to know
how far the integration of the MotionPlus into the pd-external went  
meanwhile.


I setup up my laptop-environment and downloaded the latest stuff from  
svn.


So my first step was trying to compile it on my ubuntu laptop and some  
questions aroused, which
are based on the fact that i still dont know enough of c-programming  
and the compilation process.


I looked into the makefile.org file and tried to set up all pathes  
according to my system and here is my first

question:

it is referring to this part of the makefile.org


PD_PATH=../../../pd

# specify the path to CWiid:
#CWIID_PATH = $(ASCAPE_PATH)/usr/lib
LIBCWIID_PATH = "cwiid-svn/libcwiid"

##
# You shouldn't need to change anything beyond here! #
##


ifdef PD_PATH
PD_INCLUDE := -I$(PD_PATH)/src
PD_EXTRA_PATH := ../../../../lib/libs
PD_DOC_PATH := ../../../../lib/pd-help
else
PD_INCLUDE := -I../../../pd/src
PD_EXTRA_PATH := /usr/local/lib/pd/extra
PD_DOC_PATH := /usr/local/lib/pd/doc
endif



Since i have a somewhat unusual location of my files i ask my self if  
these pathes have to point to the locations where these files are

(taken from wiimote.c file)



#include 
#include 
#include 
#include 
#include 
#include 
#include 




Is that Right ???

I am always confused whether the path means the location of the  
sources or the binaries.


I get the following error:
in line 55: balance_cal hat unvollständigen Typen
unbenutzter Parameter für "mesg", "timestamp" "ap"

nicht deklariert für "CWIID_FLAG_MOTIONPLUS"


i guess some pathes are not set right

Another thing i never know wit the declaration of pathes...

When do i use " " " quotes ??

like in

PD_PATH="/opt/sw/pure-data/pd"
or
PD_PATH=/opt/sw/pure-data/pd


do i need the first slash ??


why is somtime an "I" used and sometimes not ?

---

i looked for the locations of my header files:

#include 
/usr/include
#include 
/usr/include/sys and
/usr/include
#include 
#include 
#include 
/usr/include and
/opt/sw/pure-data/pd/src
#include 
/usr/include
#include 
/opt/sw/cwiid-0.6.00/libcwiid/
/usr/local/include

So my makefile should look like that - i thought

---

PD_PATH=/opt/sw/pure-data/pd

LIBCWIID_PATH=/opt/sw/cwiid-0.6.00/libcwiid

and further down:

PD_INCLUDE := -I$(PD_PATH)/src
PD_EXTRA_PATH:=/opt/sw/pure-data/pd/extra
PD_DOC_PATH:=/opt/sw/pure-data/pd/doc



I appreciate any help

Thanks Luigi

I continued working on the PD-external a bit the last weeks, and I

@Mike Woz: Can we put it in the PureData development svn ?

What I did was basically integrate multiple bluetooth dongle

haven't used the MotionPlus so far, but as I remember my collegue

Hello there,

   i am writing to you because the web told me, that   
you are actively developing or working on the cwiid-library or the  
Wiimote-PD-External for Puredata.


I worked on a music-improvisation project with the wiimote and  
wrote quite a bit of PD-Patches and used the PD-External on linux,  
that  depends on the cwiid library.


I stopped further development because of the shortcomings due to  
accelerometers only and the complicated IR-Things with the wiimote.
When i heard of the release of the MotionPlus, i was very excited  
and  was looking forward to the time, when the MotionPlus was  
usuable with  the PD-External.


So now my question:

Is it possible to use the MotionPlus with a recent version of  
cwiid  and the pd-external ? What do i need to do for that ?

Simply compile the PD-External against a cwiid-MotionPlus branch ?

Did you make any tests with that ? I could read that it is still  
more  or less beta...


I further would like to know if you are planning to continue  
working  on that, to know if in the near future i can count on a  
more or less  stable release, or if this will always stay a more  
or less unstable beta-experiment project.

1. start jack

2. start pd working with jack as audio engine

What about this:
Perhaps indicate the successful loading of those files in the post
window instead of posting an error message when the files are not around.
I routinely check the Pd window for errors at startup, and stumble
accross the gem.conf "error" messages. Wait, hu? What's there? (relief)
oh, only the new gem feature. :-)
Since gem.config is an optional and probly very useful mechanism
changing the way the file loading mechanism reports back might make the
current "problem" much less of an issue?

'well, it happens whenever there is a need to reparse the contents of
the box.
obviously, this is at load time.
it also happens when you just create a new object (including msgbox).
it does _not_ happen, when you just duplicate an already existing
object, because Pd is clever and has already parsed the contents of the
original objectbox and there since it has not changed (because you
cannot change the arguments of an object with duplication)
and it does happen, when you modify the object's contents (because Pd
has to figure out whether you added/deleted arguments).

No, as I noted before it also happens if you edit the message box manually.

Until you click on the message box in edit mode, and for example add a 
space (or whatever) at the end, and delete it if you want, to leave the 
content apparently unchanged. Then the content of the box is reparsed (I 
guess) and the "123" becomes a real float: if you bang it, the [+] will 
perform the sum successfully.

like that.

or whether you want to use threaded image loading or not.
(i couldn't think of a way to not want that; till karmic...)
((right; we shouldn't use configuration to circumvent bugs))

anyhow, i believe that a patch should be as cross-platform as possible.
so indeed something like "driver v4l2" is ugly since it is non portable.

i also believe that machine configuration should be machine

I think, it only happens on saving or reloading of a patch, though. For example
in the attachement a numeric symbol is generated with [makefilename %d] and
written to a message box. While this symbol looks like a number, it is in fact
a symbol (as intended) and cannot be used for calculations (but it can be used
as text in Gem). However after saving and reloading the patch, the message box
converts it to a float, so now you can use it with math but not as a symbol
anymore.

I think, you're right. It extends to many places in the Pd editor. While for
example the symbol box can display symbols with backslached escaped spaces, you
still cannot enter them into a symbol atom "manually" i.e. by typing.

There are some other fat filters in rj like e_lop2 and e_lop4. They built on a
pure pd implementation of GG's coefficient calculators (which are available
separatly as well as "u_lowpass" etc.

the nice thing is that you don't have to use it if you don't like it

i will not use it because i also prefer the "everything in one patch" 
: you have less surprises when sharing patches.
(that is also why i think a good patch is a patch that could start 
with -nopref flag on pd startup)


I totally agree, we should be working towards everything in the patch, 
and they should work with pd -nopref.  Sure, no one has to use it, but 
if someone does use it, and then you want to use their patch, then you 
have to use


it's the same problem than someone using pd pref file to load path and libs...

except that having a gemwin default size is not so important regarding to not 
having a lib when loading a patch.




but i would understand someone that set gemwin framerate at 50 fps 
because the default 20 fps is a nonsense...


cyrille



Isn't that changed by doing [gemwin 50]?  That doesn't seem so hard that 
a gem.conf is needed.


when loading Gem examples, i don't bother to change it in order to try it. but 
i'm still annoy by the 20fps...

a nice use i see with this conf file is to change default video in device.
so that you don't have change your patch if you change computer (1 with V4L and 
1 with V4L2 webcam)...

the conf-file is to replace the env-vars.
