# An image sequence follows the pattern, defaultCanvas0-000000000.png (9 zeros)
# video codec is libx264
# pixel format yuv420p
# output file is named out.mp4
ffmpeg -i 'defaultCanvas0-%9d.png' -c:v libx264 -pix_fmt yuv420p out.mp4

#if you want your image sequence to start on a different number than index 0, use the -start_number parameter

#General rules for working with shaders in OpenFrameworks

1. in main.cpp, set the GL version to 3,2:

  ofGLWindowSettings settings;
	settings.setGLVersion(3,2);
	ofCreateWindow(settings);

2. in ofApp.h, declare your shader member variable:

  ofShader shader;

indefinit

#include "ofApp.h" //include ofApp so you can use OF defined functions and vars
class Ball {

  public:
    Ball();//constructor
    ~Ball();//destructor
    //current ball position, you'll need to initialize 
    //this somewhere in your constructor or another method
    ofVec2f mBallPos;
    bool checkIntersects(const ofVec2f &positionToCheck);

Learnings from working with Open Lighting Architecture for Mac OSX 10.9.5:

On compiling the OLA library from source

Getting the OLA c++ source, compiling it, and running the OLA daemon with Max/MSP to send pixel control data over E131.

• I had a lot of initial trouble getting OLA to compile and run on my system. My goal was to eventually control LEDs with DMX/E131 protocol using Max or another client application (built in Openframeworks, Cinder, or Processing).
• I found that my library compile problems were coming from Macports. The Official OLA documentation recommends installing with Macports but in practice Homebrew was a better option for me. Here is some info on Homebrew. http://brew.sh/ Once you have homebrew installed, you should be able to run the command brew install ola --universal in your terminal, which will install OLA to /usr/local/Cellar and symlink to /usr/local/lib directory. Sometimes homebrew installs the package but does not link it. You may have to run

So you want to bundle your openframeworks app and not have to worry about that pesky "data/" directory... follow this stack overflow article:
http://stackoverflow.com/questions/4882572/how-to-bundle-an-openframeworks-application-in-xcode-relative-resource-linking

TLDR: First you need to tell xCode to copy your /bin/data directory into your application bundle by adding a build phase:

1. Click on your project in the Project Navigator
2. Select "Build Phases"
3. Toggle open the "Run Script" section and paste in the following:

}
