I am using Processing 1.2.1 and try to create a gif-animation using the webcam as the input source. When using the gifAnimation-Library, I always get a NullPointerException.
Since I get an Exception even when I try to run the Example-Code, I guess the library (or Processing 1.2.1) contains a bug. Here is the sourcecode I am trying to run (I just used the examples):
import processing.video.*;
import gifAnimation.*;
Capture myCapture;
GifMaker gifExport;
void setup()
{
size(200, 200);
// The name of the capture device is dependent those
// plugged into the computer. To get a list of the
// choices, uncomment the following line
println(Capture.list());
// And to specify the camera, replace "Camera Name"
// in the next line with one from Capture.list()
// myCapture = new Capture(this, width, height, "Camera Name", 30);
// This code will try to use the last device used
// by a QuickTime program
myCapture = new Capture(this, width, height, "USB Video Class Video", 10);
GifMaker gifExport = new GifMaker(this, "foo.gif");
gifExport.setRepeat(0);
}
void captureEvent(Capture myCapture) {
myCapture.read();
}
void draw() {
image(myCapture, 0, 0);
if (keyPressed == true) {
gifExport.finish();
myCapture.stop();
}
else {
gifExport.addFrame();
}
}
Do you have any hints for a workaround? Maybe a better Gif-Lib?
