In p5js editor, I wanted to test the example called “capture” to turn on my webcam on my mac pro. The code must be correct since I used the example that already existed, but the camera is not turning on and I do not know why. It works in the web editor in p5.js, but not on the editor on my computer.

the console says,

{  
“constraintName”: “”,  
“message”: “”,  
“name”: “InvalidStateError”  
}

```auto

```

let capture;  
function setup() {  
createCanvas(390, 240);  
capture = createCapture(VIDEO);  
capture.size(320, 240);  
[//capture.hide](https://capture.hide)();  
}

function draw() {  
background(255);  
image(capture, 0, 0, 320, 240);  
filter(INVERT);  
}

```auto

```

Does your website allow the camera to be used?

Yes, the webcam works fine with the web editor!
