Hello all!

I'm new into Processing and I'm having some problems acquiring video from my webcam.

I'm using windows Vista 32 bits and my webcam is a Chicony USB 2.0. I already installed quick time (version later than 7) and I'm able to use the examples to play videos (loop and pixelate examples) but I can't use the ones for video capture.

I get one error message, saying: "No capture could be found, or the VDIG is not installed correctly"

I already tried to access the VDIG website (vdig.com) and install it but the site is down...

Any help on this?

Thanks in advance!

Best regards,

Hello again!

Thank you for your advice. I've installed version 101 and 105 but the video I capture is not correctly displayed.

It seems deinterlaced and I cannot change the video format from SECAM to NTSC or PAL. Below my camera (Chicony USB 2.0 WDM) listing it also says composite ("composto" in portuguese)...

You have a screenshot of all this here:
http://www.fe.up.pt/~dee08007/bad_video.jpg

If I run the example for capture video (ginven in the website), as follows:

import processing.video.*;
Capture myCapture;

void setup()
{
 size(100, 100);

 myCapture = new Capture(this, width, height, 30);

 // 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);
}

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

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

(Using the previous code)... I'm able to see a capture good pictures, but exhibiting a very small field of view (100x100). If I increase further the capture window, to 300x300, for instance, the video I capture is again deinterlaced... :(

Any hints?

Thanks in advance!
