Thx a lot,

Unfortunately there's another problem.The only Video I can load into pix_film seems to be with the following Codec:

All the other formats I tried didn't work. But I need to play Videos from different smartphones.

In the manuals I read it seems like it should be possible to play most formats which I can play back with VLC player.

How can I fix this problem?

Thx a lot!!!

Please help! Sooooo many hours trying to figure this out, should be simple I think but I'm not a sophisticated user of Linux.

The Gem objects appear properly when I open the windows, but whenever I try to open/create a gemwindow, it immediately crashes (however, it seems to respond when I change the data - for instance, I can see color changes when i make those changes, but again, the gem window crashes immediately...)

A possible solution lies here but haven't been able to get a response when I attempt to implement this

Why does Gem crash when creating the Gem-window? !

When I try to create a Gem-window, my X-server crashes (or worse)? btw, I am using Ubuntu/hoary with fglrx drivers.
quick

try setting the environment variable GEM_SINGLE_CONTEXT to 1
explanation

Gem establishes an (invisible) openGL-context at startup, even if no Gem-window is created yet. When you create the Gem-window, a 2nd openGL-context is used (which shares some properties with the invisible context).

For some reasons this seems to be not possible with some gfx-drivers (e.g. ATI's proprietary fglrx drivers) and some window-managers (i suspect compiz/beryll), leading to crashes of the X-server and/or system freezes.

The current workaround is to set the environment variable GEM_SINGLE_CONTEXT=1, which prevents this dual-context magic.
how?

if you are starting Pd from the bash, you can start Pd/Gem with GEM_SINGLE_CONTEXT=1 pd -lib Gem
on bash, you can also set this permanently by adding a the line export GEM_SINGLE_CONTEXT=1 to either ~/.bashrc (the bash-configuration file in your home-directory) or to /etc/bash.bashrc (to set it for all users)

• newer linux user but though I followed compiling instructions for installing Gem, it seems never to create a conf file.. when I open pd-extended in terminal, I get this message:

open: ./gem.conf: No such file or directory

any thoughts or input would be VERY APPRECIATED, thanks!

Could anyone give me some tips for how to compile the GEM library for Vanilla? Maybe just a short list of instructions to get me started? I am a total noob at this stuff and there are so many files

PS I'm sure i have to compile because just moving the GEM library into one of pd's paths gives me this at the console:

/Applications/Pd-extended.app/Contents/Resources/extra/Gem/Gem.pd_darwin: dlopen(/Applications/Pd-extended.app/Contents/Resources/extra/Gem/Gem.pd_darwin, 10): no suitable image found.  Did find:
/Applications/Pd-extended.app/Contents/Resources/extra/Gem/Gem.pd_darwin: mach-o, but wrong architecture Gem: can't load library

Hi, thought I'd post here even thought the thread is old before starting a new topic because my problem is exactly that as described here, though none of the suggestions have help and no one seems to have my exact error console output, which is as follows:

So I've added the word "gem" (with no quotes) to the Startup list, and the external library locations (whose paths can be seen in the above output) yet it doesn't work.

Any ideas? I've verified that both pd and gem are installed and at the lastest version. I'm using Ubuntu 11.10

Hi guys,

i'm trying to implement a system to track robots by a webcam. My problem is, it is difficult to track more than one robot with the PIX basic objects.

My system comport three robots identified by plates of different vivid colors, red, green and blue, and a platform with amoeba form that probably will be white or black in the final.

I've already tried to implement the track with pix_movement and it worked very well with just one robot. To work with two robots i thought it would be better to separate the RGBA matrix, to focus in each color, and have a functional track of each robot separately. BUUUT, it did not work very well, because the separated matrix did not present a good contrast of the predominant color, as a nice and big red mark over the red robot, for example, Instead of it, i had a very messy image caused by the interference of the background colors.

to filter and track the image i used:
pix_separator - to use 3 different images
pix_threshold - to keep just the wanted color, if it is high enough
pix_gain - to intensify the required color
pix_movement - to track the movement of the robot
pix_blob - to track the center of mass

One solution i thought its to use a filter that can recognize the image in another format, not RGBA, a format that differ colors, saturation and highness in different values and scales. Does it exists?

Thanks very much for reading it, i would be very glad if you could help me! =)

hey,

I don't know but I wonder if maybe there isn't a more general problem going on right now (though it seems simple and wierd so I dont get it)
I am also having trouble loading abstractions even though I have done it quite a lot before, in particular (I posted this problem a few days ago but am posting in response to your problem in hopes that it might be a more global problem - though my abstractions, other than the ones mentioned below, load so I dont understand)

specifically, was the problem with the path not being recognised?

anyway -
Hello everyone,

This is a strange problem because I have loaded libraries and things with the 'Paths' dialog under the file menu before and had no problems.

I am trying to get Chris McCormick's s-abstractions to load. The folder is in the same folder as my other libraries and it is listed in both the "paths" and "startup" areas. It wasn't before but I added it.

I am running windows 7 64 bit. Another oddity that I noticed is that in my Program Files (x86) which is where the 64 bit programs live, I have pd installed and the folder is simply called pd. However in the Program Files folder (missing the x86, where the non-64 bit programs live) I have a folder called "Pd-0.42.5-extended"

I wonder if that couldn't be the problem. The s-abstractions folder is included in both though...

Hopefully somebody has some idea about this...

((anyway sorry to post twice but I hoped maybe there was some common problem there))

GEM interactive GUI, evaluation so far

I tried to translate one of my setups, SliceJockey, to a GEM GUI. But by now, when the work is almost done, the setup is full of not-so-ideal workarounds and I must conclude that it worked just more straightforward with Tk.

I won't completely give up on GEM, because it is fairly well possible that audio and control procedures in SliceJockey are somehow 'tuned' to the Tk GUI because they were developed there, and a setup developed with GEM right from the start may work smooth.

Anyway, I've noticed some characteristics of GEM which are sort of incompatible with the notion of a general GUI framework. GEM is optimally suited for motion graphics and video manipulation. It is efficient where Tk is slow, when it comes to updating the screen. But the other way round is also true. Rendering of static information is in some cases much easier with Pd Tk than GEM. Some GEM bottlenecks:

• good quality text rendering (crossplatform, with [text2d]): way too expensive

• plotting of static arrays like sample waveform: cumbersome and expensive

• separate Pd instances required for GEM and audio patches

GEM aspects which I find *very* attractive for GUI purpose:

• GEM window with all it's content can be created at any size, and thus accommodated to screen size

• fairly easy to set up an x-y pad with multiple objects of any shape or size

• fairly easy to animate objects in response to audio data

• option to create pictogrammed control objects

Katja

Since a while I design Pd patches in such a way that they can be operated from a touch screen. Bangs and toggles with ample size (50x50 pix), and in some cases a large x-y field where standard Tk GUIs can be moved around in runtime when they receive [pos x y( messages. Like a Kaoss pad, but now with dozens of effects and parameters available simultaneously.

Though I'm happy to see that Pd can be operated from a touch screen, layout options with the Tk GUIs are very limited of course. Therefore I now consider using GEM for interactive GUI purposes. Pictograms could be used to indicate controller types, and audio settings could be reflected not only with numbers, colors, or position, but also with motion. For example, a cogwheel represents a sample or loop, and it's rotation speed indicates playback speed. GEM could give more information on controller state than Tk objects, making the interface more intuitive. And certainly more inspiring!

But now comes my question. Where Tk GUIs are made for interaction and visualisation, GEM seems to be made for visualisation mainly. So far, I found no simple method to make clickable objects in a GEM window, replacing toggles and bangs for example. How can you prompt a graphical object in the GEM window to identify itself on click? Does anyone know of patches where GEM is employed for such purposes?

An example of a Tk-based touch interface which I'd like to translate to GEM is described here:

Thanks in advance for your suggestions,

Hey

Once again I'm back on vista. My brief journey to puredyne goes something like this.

from puredyne
partitioned new hard drive with 4 partitions 1-swap , 2 ext4 200Gib, 1 NTFS 200GB . Copied Vista to NTFS partition with gparted(started to do this with dd but with new Gibabits stuff I was skeered but hey a platter is a platter and a cluster is a cluster right). Actually there was a 5th partition in there which was the vista restoration partition but I eventually deleted it for obvious reasons.

Removed old drive ,
took machine to ethernet connection with internet,
booted to vista ,
installed Norton virus scanner - only 1 virus, 2 tracking cookies, and one gain trickler after over a year with no virus scanner, Thats pretty good and shows you can be selective about what you download and where you visit on the web and not get any viruses.

Was trying to get windows movie maker to work with mov codec which it doesnt.
Installed auto updates for the first and only time. this took about 3 hours and still needed to install service pack 1, 2. Aborted trying to update win movie maker

****Problem 1***** MS movie maker does not work with GEM mov video output codec.

Installed latest Nvidia drivers for vista.
Woohooo OpenGl hardware acceleration GEM works so much better in vista now.

*****Problem 2********ASIO for all does not allow 2 applications to run with audio and midi at the same time. If I wanted to run Widi and play my guitar so puredata can receive midi input from guitar ASIO will not allow it but ASIO for all is the only way I can get latency down so this would be feasible.

Got frustrated.

Installed fresh copy of puredyne onto 2nd ext4 partition.
ran puredata audio latency good with fresh install. gem video bad.

used synaptics to install nvidia drivers. v185 I think.
ran GEm error no opengl config.

downloaded gdeb , flash player, google chrome, nvidia drivers from nvidia site.
installed gdeb from terminal, flash and chrome from gdeb.
rebooted to log in as root and iunstalled nvidia drivers.

woohoo hardware acceleration for opengl

******problem 3************
gem works great but audio glitches with puredata window visible.
when only gem window is visible i can unaudioglitchily move the mouse around to control same parameters that would normaly be controled with sliders in pd window.

Seems like before i upgraded nvidia video drivers hw:do o whatever it is, was listed in JackD as realtek HD Audio, now it is listed as NVIDIA HD Audio.

So Gem works great but not when Pd window is open and I think my audio drivers were replaced with Nvidia.

I would really like to get back to my patch and stop wasting time on these operating systems and hardware configurations I thought in the last 15 years all this hardware acelleration and autodetection would be figured out but no all we got is rc.0, rc.01, rc.02, rc, etc...... instead of just rc.d.

Ok I'm getting an error when I exit puredyne that says pid file not found is jackd running. anyone know what that means?

Also does anyone have a keymap for gem keyboard for linux, windows and mac so I don't have to record them.

Any suggestions about what to do about my ASIO problems in windows?
Any suggestions about my audio driver in Linux?
Any suggestions about my GEM mov video / windows incompatibilities?

I can import the mov video and audio to SF Acid 3.0 and output a 2Gb avi then import it into windows movie maker but this is crazy to do for a 7 minute 12fps 320x240 video.

Ahhhhhhhhh!
Any suggestions are welcome!

PS I believe someone could rewrite puredata's audio and video interface in assembly language to control their hardware before figuring out how to get these operating systems to do it.

yup!

It's super weird.

but yeah, so far, I can only get 1200 1600 and higher. Maybe if I worked in YUV?

edit: I forgot to mention that I'm running a macbook pro with snow leopard.
