Re: [PD] Console error: 'Out of memory'
OK. For a slideshow, i will use [pix_buffer] or [pix_multiimage]... My preference is for [pix_buffer]. With [pix_buffer], you also need [pix_buffer_read] to select the image you want to show (see help about these two objects) But, I think, it is a good idea to reduce the resolution of your pictures to fit your [gemwin] resolution... ++ Jack Le 21/04/2014 18:27, Claire O'Connor a écrit : I used pix_image! I haven't tried that, but perhaps that might work. I may just end up cutting down on my images. It is strange though, because my 'sllideshow' is set to loop and when it starts again, the previous images that were already opened, open again even though the 'out of memory, can't allocate memory for an image' error comes up.

With that short buffer settings it is unusable for everything more CPU intense than sine test tones though. The only way to get Pd to run reliably under some load on my box using the HDSP is to use jack with 256 frames at 2 periods/buffer. Now what is weird is that the built in soundcard of my box is able to do the same thing without problems with just 64 frames at 3 periods/buffer in jack. Again with the HDSP, once I start adding Gem and let it render a single geo, I do get many audio dropouts unless I increase jack's buffers to a minimum 2048 frames at 2 frames/buffer. I tested this using two different HDSP cards on two different Debian boxes, using the -rt flag, realtime and non-realtime kernels, optional callbacks and different sleegrain setting.

It seems to work fine with Pd-Ext 0.42.5 (but not with Pd-Ext 0.43.4).
That leads me to believe it has something to do with the GUI rewrite,
which happened between 0.42 and 0.43.
Here's the relevant code-- line 90 in source/TUIO/TuioClient.cpp
if (socket!=NULL) {
if (!socket-IsBound()) {
delete socket;
socket = NULL;
} else std::cout listening to TUIO messages on UDP
port port std::endl;
}
***
Somehow std::cout must be printing to the console in 0.42 and sending
to the gui (i.e., tcl) in 0.43.
If you send a GUI message to tcl it interprets the first word as a
command. That's why you get the error below.
I don't know enough about c++ to give you a fix, but I'm sure someone
else on the list does.
Btw the relevant code is here:
http://sourceforge.net/projects/reactivision/files/TUIO%201.0/TUIO-Clients%201.4/TUIO_PureData-1.4.zip/download?use_mirror=tenetdownload=
Then unzip the nested source.zip.

[PD] audio output AND input with the Rpi?
Hey folks, Apologies as this post is not strictly about Pd, though Pd will be a crucial part of my final setup so whatever solution I find ought to work with Pd. Also, there is a chance the issue might lie with Pd. I just don't know. I'm looking for a usb bus-powered audio interface for the Rpi that can take a stereo input and provide stereo output *at the same time.* * * I have tried a couple different images and a couple different audio interfaces, to no avail. Perhaps there's something can be done with one of these setups to get it working? First, the Pd-LA custom Raspian (v1) image and Pd 43.2: ..with Behringer UCA202 (at 44100khz): Alsamixer picks the device up but the input section shows nothing. Pd (gui) audio preferences allows selection of the interface for both input and output. Output only is lovely and clean but as soon as the device is selected for audio input the audio quality drops horrendously (vaguely recognisable from the original signal).. ..although what gives me hope is I CAN software monitor the input (poorly) in 'Test Audio and MIDI' with this arrangement. ..with Behringer UCA202 (at 48000khz): Output only in Pd is poor (beating and popping sound - possibly sounds like a samp rate conversion issue). When device is selected as Pd input software monitoring is possible and oddly, though the result is still poor, there is effectively no drop in quality from having the device selected only for output and the monitored signal sounds drastically better than at 44100khz. ..with Turtle Beach Amigo II* (at 44100): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and only the output is selected in Pd it works but with a lot of jitter. Selecting the device for input too causes a further drop in audio quality although again I can software monitor the input in 'Test Audio and MIDI' If plugged in after boot the OS crashes. The Satellite CCRMA (operating via ssh) and Pd-extended: ..with Behringer UCA202 (at 44100 and 48000): Alsamixer picks the device up but again the input section shows nothing. If I have the device plugged in from boot then I get the same behaviour with it as I do in Pd vanilla on the Pd-LA Raspian image, ie. software input monitoring but at an extremely poor quality. If I don't plug the device in from boot I see it in Pd audio prefs but get this: ALSA input error (snd_pcm_open): No such file or directory ALSA output error (snd_pcm_open): No such file or directory from the Pd terminal and this ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card oops: ALSA cards not reported in order? from the ssh terminal. ..with Turtle Beach Amigo II* (at 44100khz): Alsamixer shows both input and output and allows to change gain of both. If plugged in from boot and then only output selected in Pd I get clean audio out. If I try to select the Turtle Beach as audio inout in Pd then Pd stalls indefinitely when I try to 'Test Audio and MIDI' or make anything in a patch. Same direct input monitoring by default. Also get ALSA input error (snd_pcm_open): Device or resource busy ALSA output error (snd_pcm_open): Device or resource busy from the Pd terminal if I don't have it plugged in from boot, though no message in ssh terminal. *It also appears that by default the Turtle Beach does direct input monitoring of some sorts, the output stage sending out a clean copy of whatever signal is going into the input stage whenever the device is plugged into a usb port. With the Pd-LA image this occurred simultaneously while input monitoring in Pd. I guess this is part of the design of the Turtle Beach, though their documentation is devoid of any useful info regards this. If this is the case then this ain't the sound card for me, though clearly some might find this a very useful feature. Just to give a bit more info about what I'm attempting: I wish to run the stereo input from the Turtle Beach through Pd, play with the audio signal using data from an accelerometer (not nearly there yet) and then send the audio out through the Turtle Beach's stereo output. Apologies for the essay. Hopefully my findings are useful for others and hopefully I can get my rig working! Help muchly appreciated. I've probably left out some crucial bit of info so please shout me if I have! Cheers, Chris Jack.

Hello,
Le 05/10/2013 22:51, Py Fave a écrit :
in fact my problem is not solved .
it seems like the feedback effect happens everywhere but on the
surface drawn by the shader .
According to the patch, the feedback is applied on a [square 4] (where there
is also the [torus 2]).
Then, [gemframebuffer] 'snap' the whole 'inside' [square 4]. And your torus
is inside this snapshot (as texels and not vertices).
yes ,and then there is some feedback on the texels of the square .
but in my patch if i rotate the torus i get some feedback but not on the
shaded part (only the silhouette of the torus . i don't know why .
i would like everything to go in the feedback loop .
in fact i try to have trails that show geodesics on a surface
later i plan to replace my torus with other models .
i use a torus , in perspective wich has a shader applied .
i tried the following workaround(archive is joined ) , but still no luck .
the file to open has a OPEN in name .
It seems there is no circle4.geom, [receive13] and [nshader0]
objects/abstractions in your .zip.
sorry i forgot .
receive13 only is missing .
it's part of ext13 library (and is in pd-extended iirc)
http://puredata.info/downloads/ext13
[receive13 nothing ]could be replaced by receive nShader1
or all the shader abstraction can be replaced by the classical shader network
with fragment shader = circle4.frag and vertex shader = circle4.vert.
no .geom was used
i would like the dots to have the feedback ,
or dots + geometry alltogether.
I can't see dot in your patch (or gem window), maybe they come from geometry
shader (which is missing) ?
i didn't use geometry shader . just fragment .
glsl program complains in the abstraction but no harm here i think
i tried pix_snap2tex ( using gems.feedback from pdmtl abstractions) too
but no luck because we can't choose the mixing function .
and i would like only white to make trails .
and i don't know how to keep the supporting geometry from appearing .
the torus should be full black with a white trail only .
A simple possibility is to use 2 torus, a black 'on' a white. And use the
white for the trail ?
An other way :
white torus as texture
|__ in the feedback __ output feedback as texture
|__ convert white in black texel __ output black torus as texture
Then mix (multiply) black torus with white feedback to get a black torus
with white trails.

Jack
i'll send a modified patch a bit later .
Thank you so much i see some good things from the last patch you sent .
it is not what i want to do but opens other directions
and perhaps i was focusing on one method but there seems to be alternatives .
i'll update this thread tomorrow .
i have to keep some life away from computer :-)

Hello, Le 09/10/2013 18:20, Mario Mey a écrit : Sorry, guys, for entering in this thread without reading all the mails. But I want to ask you something. I use readsf~ to read a speaking recorded files, sounds and songs (some songs are 3 or 5 minutes long, but there's one of 20, so, I thought readsf~ was better that put the files into arrays). Readsf~ gives no information about the time, and it would be very usefull for me to synch with an animation in BlenderGameEngine. If you want to get the length of a sound file, you have several possibilities : - use [wavinfo] from ext13 - use [soundfile_info] from iemlib - use [shell] with your favorite command line to get info on soundfile ++ Jack Also, yet, I don't know if readsf~ is the one that makes noises when BlenderPlayer is rendering in 3D in full screen. I just thought that the computer can't process that 3D rendering and has Jack with low latency. Maybe readsf~ is the problem... Anyway, I wanted to ask you about readsf~: Is readsf~ stable? Does it consume so much CPU? Is there any other object better to use? Maybe the one you are talking about in this thread... I don't need to varispeed, for example. Just read files, play and know its position in time. And low CPU consumption. Thanks. PD1: I'm on Ubuntu 12.04. PD2: what about THREADLIB and SNDFILER to open files in a different thread?

receive13 only is missing .
it's part of ext13 library (and is in pd-extended iirc)

[receive13 nothing ]could be replaced by receive nShader1
or all the shader abstraction can be replaced by the classical shader network

no .geom was used
i would like the dots to have the feedback ,
or dots + geometry alltogether.
I can't see dot in your patch (or gem window), maybe they come from geometry

i didn't use geometry shader . just fragment .

According to the patch, the feedback is applied on a [square 4] (where
there is also the [torus 2]).
Then, [gemframebuffer] 'snap' the whole 'inside' [square 4]. And your
torus is inside this snapshot (as texels and not vertices).
i use a torus , in perspective wich has a shader applied .
i tried the following workaround(archive is joined ) , but still no luck .
the file to open has a OPEN in name .
It seems there is no circle4.geom, [receive13] and [nshader0]
objects/abstractions in your .zip.
i would like the dots to have the feedback ,
or dots + geometry alltogether.
I can't see dot in your patch (or gem window), maybe they come from
geometry shader (which is missing) ?
i tried pix_snap2tex ( using gems.feedback from pdmtl abstractions) too
but no luck because we can't choose the mixing function .
and i would like only white to make trails .
and i don't know how to keep the supporting geometry from appearing .
the torus should be full black with a white trail only .
A simple possibility is to use 2 torus, a black 'on' a white. And use
the white for the trail ?
Attached is an example of that method.
Hope it will help you...

Jack
An other way :
white torus as texture
|__ in the feedback __ output feedback as texture
|__ convert white in black texel __ output black torus as texture
Then mix (multiply) black torus with white feedback to get a black
torus with white trails.

btw i'm on windows not my choice.
i have to share the screen with other programs wich are windows only

JackPy Fave pyf...@gmail.com a écrit :first thanks both for your help.
i was tired yesterday evening.
jack , i have a problem with your patch.
i had already similar problems before, that's why i wanted to use some
shader in the feedback chain .
it works ok BUT with very long feedback ( 0.999 alpha ) values i get a
ghost image,
the point never diseappears( because perhaps of a bad approximation in
opengl ) .
ie : color 1 1 1 0.995
leaves traces
is that a problem with my graphics card ? i don't think so .
i join a clumsy correction test , with makes things flicker a bit too much .
do you have a better workaround?

Hello Patrice,
I just added a line at the begining and an other one at the end of

I also change the texunit ID backbuffer to 0 in the patch.
You can change alpha feedback with the number box i added in the patch.

Re: [PD] [OT] get video stream with pdgst from XIMEA camera
Hello, The answer about v4l2 driver for xiQ camera from Ximea : Dear Mr.Jack, Based on information of our linux implementation specialist we are not planning implementation of v4l2 because it is quite complicated task and there are no big potential from current customers. Probably gstreamer interface would be simpler for implementation, but unfortunately also this interface is not in our plan pipeline. Best regards Hello, I have a xiQ camera and test it on my Ubuntu. It works well with streamViewer provided by your staff. But for a lot of people working under linux platform like me, it would be very nice to use v4l2 driver. This is free/open and a standard on linux. Are you working on this solution (to make v4l2 driver for your xiQ USB3.0 camera) ? Best! ++ Jack For peole interested in the xiQ cameras : Ximea API/Gstreamer have worked during more 24 hours without problem on my computer (Ubuntu 12.04, kernel 3.8, gstreamer 0.10).

[PD] [OT] get video stream with pdgst from XIMEA camera
Hello,
I would like to get the stream from a XIMEA camera using gstreamer.
There is an example (in the XIMEA Linux Software Package) that use
gstreamer to get the stream. This example works fine on Ubuntu 12.04
(with kernel 3.8) and Ubuntu 13.04.
But i would like to get the stream with v4l2sink/v4l2src from gstreamer
with pdgst (or better, from [pix_video] ??? :).
My skills in C++ are bad and if someone can help me to modify the source
code (attached, dependencies : GTK+-2 and GStreamer-0.10) to make it
work only with v4l2src, it would be very nice.
The XIMEA Linux Software Package can be downloaded from :
http://www.ximea.com/support/wiki/apis/XIMEA_Linux_Software_Package
Thanx.
++
Jack

But it's probably also much slower for that same reason. One drawback to [drawsprite] is if you wanted to abuse it to draw a large image sequence-- say a video clip-- you're going to use a ton of memory loading the images into wish's memory. And by default tcl/tk doesn't free that memory back to the OS. However it does free it up within tcl/tk when the corresponding [drawsprite] is deleted-- so if you delete it and undo a bunch of times it won't consume more memory than it did in the first place. But for small sprites this isn't really an issue, and once the images are loaded it is very cheap to copy/cut the scalar images on a canvas. -Jonathan Jack ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list Is it possible to add an argument to [drawsprite] to load the first X frame of the video ?

(through the (semitransparent) front side of the sphere) Short answer: no. Long answer: no, because transparency and OpenGL don't quite get along as nicely as you might expect. Rendering order (of every triangle that makes up every object) matters a great deal. Transparency involves blending the current triangle with whatever is behind it. OpenGL uses its depth buffer to keep track of what's been drawn and how far away it is at each pixel - keeping only the nearest value - whether it was rasterized before or after the previous triangle. You need to draw non-transparent stuff first, then sort every transparent triangle into depth order, possiby splitting up any transparent triangles that intersect each other into smaller triangles, then render them in order urthest from camera first, nearest to camera last. I'm pretty sure that Gem doesn't support depth sorting. You might be able to hack it and get something that looks mostly ok some of the time by rotating the sphere to change the depth order vs render order of the triangles making up the sphere, but it will be very fragile... Claude thanks, i was expecting something like this. i guess i will think about an alternative approach to that instead of hacking around with depth sorting and rendering order within a single geometric object. matthias ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list Hello, I think it should be doable using culling (GL_FRONT and GL_BACK). But, in this case, you need to render two times the sphere (one with culling GL_FRONT and the other with culling GL_BACK) and then adjust alpha between them. ++ Jack ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Here is where i scratch my head: It works fine until you render the output of the multiblob tracker to a rectangle. I'd like to understand why this is. Is it a bug or a feature? connect the tracker to the pix_texture (where the red line is) and it will mess up the result: Hello Max, This could be interesting for you : http://www.mail-archive.com/pd-list@iem.at/msg42343.html Thanks Jack, I know – I have posted on this thread too. We solved this problem differently. Because our application was microscopy and we had specimen who were stopping their movement for a while before moving on, the continuity approach wasn't working. Since we based the blob detection on frame differences [pix_movement] rather than background subtraction from a reference frame [pix_background] blobs who were resting for a few frames simply disappeared and got a new ID assigned. Our approach is to set a time-out after we declare a blob dead. If it starts moving in the same region (size is settable too) again before the time-out, we pick up the old ID. So rather than using movement vectors as reference we used proximity. All data is stored in tables. The patch works beautifully without any externals. Have you tried? So this problem is already solved - my question was rather a Gem thing: why does is stop working when I want to render the image behind it? Do you know this? Max Sorry, i didn't see your patch in your previous post. If I try to open it, i get : arraysize blob_ids ... couldn't create What is [arraysize] ? oh, darn - seems it isn't completely vanilla then. it is an external by Juha Vehviläinen http://puredata.info/downloads/arraysize Ah ok, maybe with [expr size(table_name)]. About the problem : you need to render the [rectangle] before draw_blobs. See the patch attached… thank you jack (but still scratching my head why exactly that is, will revisit tomorrow). updated here: https://github.com/mxa/Bewegungsmelder Hello Max, In your patch, you need to put the crosses on the rectangle showing movement. These crosses and rectangle are in the same plan. Therefore, you need to render, first, the rectangle and after the crosses. Inside the subpatch draw_blob, you have a [gemhead 90], which one is banged each time it has a cross to render. But, this [gemhead 90] is rendered many times (or not) during your main [gemhead] (in the main windows). If you open the subpatch draw_blob, you can see that i add a [loadbang] and a [0 ( to stop the render of [gemhead 90] each frame, because the render is forced (many times or not) by a bang from the main [gemhead] and because you needn't to render this [gemhead 90] during the 'normal' render cycle. You can easily replace [gemhead 90] with [gemhead 10] and get exactly the same result. If you want, it should be possible to replace this [gemhead 90] with a [gemlist]. Hope the explanations are clear. I give here a small example to understand. ++ Jack small_exemple.pd Description: application/puredata ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
