Video library problem with version 0148
Aug 31st, 2008, 9:32am  
Hello everybody!

I'm at the first attempt with processing...I have been using since a few month Arduino and its developpement enviroment.

On Tom Igoe's book i found this interesting code to make Processing able to recongnize colors from a Web-Cam...The problem is that the new version ( i think ) don't load the VIDEO library well...here is the initial part of the code, where compiling get stuck:

import processing.video.*
//instance of the capture class
Capture myCamera;

void setup()
{
//window size
size(320, 240);
//list all available cameras
println(Capture.list());
//capture second device available
String myCam= Capture.list()[1];
myCamera = new Capture(this, myCam, width, height, 30);
}

void draw(){
image(myCamera, 0,0);
}

void captureEvent(Capture myCamera) {
myCamera.read();
}

When i compile i get ----> expecting EOF, found 'void
On the forum i found topic about the same problem and it seemed like it is a bug problem...on the bug page i am getting no replies, so maybe you can help!

Do you know an older version available that doesn't give such problems?

You forgot to put a semicolon after you import the video library Wink

Also you are passing too many arguments into Capture. Try this:

Quote:


import processing.video.*;  // I added a semicolon here
//instance of the capture class
Capture myCamera;

void setup()
{
//window size
size(320, 240);
//list all available cameras
println(Capture.list());
//capture second device available
String myCam= Capture.list()[1];
myCamera = new Capture(this, width, height, 30); // I removed "myCam" from here
}

void draw(){
image(myCamera, 0,0);
}

void captureEvent(Capture myCamera) {
myCamera.read();
}  



Hope this helps:)

Thank you!

I also found another tutorial on the internet, and i joined the two codes toghether and...I works!

By the way if you want to see it you will find it in another topic i've began:

Hope you will help me as you did with this Topic

THanks again!!
