Lockup with Game Control Plus by Quark
I am using the GC+ library to get Windows 7 joystick movements to processing. I then use the processing program to communicate with my Arduino microprocessor. Its a great library, awesome tutorials and documentation. My problem is it works for about 5 minutes flawlessly then my processing programs totally locks up. I cannot get the program to run again unless I reboot my computer. I am sorry I cannot follow the directions for posting code. Wow what I mess I am.
/**
Demonstration of using a joystick for Game Control Plus
When this sketch runs it will try and find
a game device that matches the configuration
file 'joystick' int the data file of the processing folder. if it can't match this device
then it will present you with a list of devices
you might try and use. Use the configurator in the Processing-->Files-->examples-->GC+ to write a data file that is included into the procesing
folder. You keymap and name various functions. These are then written down below in a code. (get matched
device and get slider).
The chosen device requires 2 sliders and 2 buttons.

Refreshing an image?
Okay, so I'm going to try and explain this the best I can and hopefully someone can help me. I have a program that basically takes a screen shot of the program window and saves it into the data folder. It then loads that image capture onto the screen where ever I tell it to. The problem that I'm having is that it doesn't load in a new image when I take a second screen shot. The new image is put into the data folder, but it doesn't replace the image that's up already.
import processing.video.*;
Capture cam;
PImage capture;
void setup() {

FFT Landscape generator
Hi there, I followed the Terrain Generator by Perlin Noise tutorial from youtube, and I tried to switch the perlin noise with an FFT of the mic audio input. X axis is fine, in the horizon I can clearly see my FFT effect, in the y axis I can't get the progressive generation, so to create a landscape from the sequences of FFT moments/frames. to get the Effect That the observer walks toward the horizon self-generated by FFT.

Very low frame rate using Spout + Processing 3.2.3
Hi there,
I've just started to try using Spout to send sketches into Resolume, but when I add in the Spout code to an existing Sketch, the frame rate drops from 60fps to around 10fps. If I comment out the spout.sendTexture() call the frame rate goes back to 60fps. I am struggling to find any documentation explaining how to use spout correctly, the example spoutSender in the processing library also only achieves a frame rate of 20fps (with the textured spinning box), so thinking it might be something else I am missing. If anyone can provide any assisstance it would be most appreciated. Thanks, regards Andrew

Libraries for text manipulation
Hello Processing members
I plan on doing an animation that pulls all the text from the screen to the middle and lets it pulse like a heart. For that I checked if I'm able to manipulate whole Strings and Chars the way I'm able to manipulate circles, for example. I found the libraries Nexttext and Fontastic, but those seem to be outdated, therefore I can't use them with Processing 3.0. Than there is the library Geomerative, which I manged to install through Processings library manager, but this one yields the error "duplicate libraries", which I can't find a , for me understandable, workaround for. I'm also using minim, since I combine the pulse with music input, minim works fine though.
Thus I'm asking if anyone here has an idea on how to fix this error, make the outdated libraries run or maybe someone has an alternative way/library to manipulate text.
Kindest regards.

Syncing video to audio
Hello everyone,
I recently started working on a project that creates visuals for music using the minim library. All is well until I export the video file using GSvideo and use windows movie maker to create my music video. The audio seems to be quite a bit behind and the visuals don't really make sense (I've tried different frames/s values and still the same issue). I'm using processing 2.0, tried using the GSvideo pipeline but I'm not sure how to export both audio and video at the same time this way (any examples you have would be very much appreciated). Does anyone have any experience with this subject? Any pointers would be great.
Thanks in advance
