Martin? Is something wrong? It's never done  Let's try to implement some gif export stuff.

i just tried using code snippet on my MAC (os10.2.8 / p5.0066) and it wouldn't work.
it said that imageio is either misplaced or nonexsistent
... it works fine on my PC.
any clues?
- - - - sample code - - - -
Code:
void setup(){
size(320, 240);
background(0);
}
void draw(){
line(0, 0, 100, 100);
save("img.jpg");
}
// save IMAGE hacked by Martin and Koenie
public void save(String filename) {
BufferedImage img = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
img.setRGB(0, 0, width, height, pixels, 0, height);
if(filename.toLowerCase().endsWith(".jpg")) {try {File file = new File(filename); javax.imageio.ImageIO.write(img, "jpg", file);} catch(Exception e) {}}
else if(filename.toLowerCase().endsWith(".png")) {try {File file = new File(filename); javax.imageio.ImageIO.write(img, "png", file);} catch(Exception e) {}}
else {g.save(filename);}
}

perhaps imageio is 1.4 only the mac version of processing defaults to 1.3, details for changing to 1.4 are in the readme.
also for the code, here's another method that might be more usable, though i'm doing this off the top of my head and haven't debugged it, so it may need a tweak or two:
Code:
// save IMAGE hacked by Martin and Koenie
public void save(String filename) {
BufferedImage img = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
img.setRGB(0, 0, width, height, pixels, 0, height);
String extn = filename.substring(filename.lastIndexOf('.') + 1).toLowerCase();
if (ext.equals("jpg") || extn.equals("png")) { // add here as needed
try {
javax.imageio.ImageIO.write(img, extn, new File(filename));
} catch (Exception e) {
System.err.println("error while saving as " + extn);
e.printStackTrace();
}
} else {
super.save(filename);
}
}

koenie: nothing's wrong.  hehe... ok, an updated version with gif capability will be posted soon (not using javax.imageio). hehe.
mrb: erm... hi, what do you mean?
mkoser: thanks. what version of java are you using on your mac? javax.imageio is part of jre1.4. it should work if you have it. then again, in my previous posting before koenie's, i inserted code to detect what version of java you're using. i've updated it to use setrgb as well as to do java version checking. (the link is right above. --- update: not posted right now, just hack the previous code and use setrgb. i'll post something loooong a little later that does barebones gif encoding). i don't have a mac right now to test this but i really appreciate feedback. 
note: ugh. fry beat me in posting abt 1.3 vs 1.4 hehe... at any rate, you can still use the other jpeg encoding method if you want to default to 1.3 ... uh yah, i was coding the gif encoder while typing this reply. hehe. got stuck with object references. BImage ...  hehe....

Yesterday I got interrested trying to save a sequence of images to (raw)avi/quicktime. Anyway my jaws dropped as well seeing the (different) specs. 
a good source on different file-formats;

koenie: there is of course... the thing is, it uses javax.imagio (using fry's code snip). this leaves out people who don't have 1.4.
elout: a little patience and you'll get it. here's a suggestion... why not look into an animated gif first?

some tips for the future video track creator:
Java Media Framework (jmf) is a nice piece of software and it is supposed produce both avi & qt, but the number of codecs it can handle is ridiculously low... (a good point: the documentation is very helpfull and it gives a very good overview the concept of time-based-media)
concerning qt for java: it rocks, but the api reference with all the java classes is not going to help you, what you need is to download the sdk, and you'll find a lot of working examples with source code (at least one of them is directly dealing with track creation).
final note: i think it's better to stick to qt for java prior to version 6.4 since it seems that all the working examples are using the "old way" (qt for java 6.4 is introducing a lot of api changes)
hands-on!..
