Hi, I’ve been looking for a reason why my code is not working. It does not matter what arguments I put in between parenthesis. The error message is always similar. Please help ☹

import processing.video.\*;

Capture video;

void setup() {  
size(600, 400);  
//Capture(parent, width, height, fps)  
video = new Capture(this, 640, 480, 30);  
}

void draw() {  
}

Hi @Danii,

you need to install the video library for processing through contribution manager. In your case, as you are using processing 3, the version for video library for processing 3.

From top level Menu choose

Hii, thanks for replying.

I already had installed the library. I tried to download the library to add it locally, but found the github repository is not available anymore ☹

Hmmm! Suspicious!?

Can’t test currently as I’m not at my box.

GitHub is still available from here…

Hello @Danii,

![image](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/7/5/756fa3485a5dd96589e5dedb099a2ca1b96d391f.png)

Rename your sketch to something other than Capture (name of the class) and it will work!
