Using p5.js on a jetson nano

p5.js Libraries
1

P5js is a javascript library that enables media presentation, interactive drawing as well as user input in an area of a web page defined as the CANVAS.

https://p5js.org/

I’ve gotten it to work with the jetson nano since it is javascript , but only as long as only primitive drawing functions are used. However, I cannot use the predefined constant, VIDEO, to access the camera.

The p5.js code I use works fine on a raspberry pi
Here is my html:

<!doctype html>
<html>
<head>
<script src=“p5/p5.js”> </script>
<script src=“p5/addons/p5.dom.js”> </script>
<script src=“sketch.js” ></script>
</head>
<body style=“margin: 0; overflow: hidden;”>
</body>
</html>

(I had to leave off the ’ > ’ inf each line of html because the text would not render properly in this forum)

and here is my sketch.js

let capture;

function setup() {
  createCanvas(390, 240);
  capture = createCapture(VIDEO);
  capture.size(320, 240);
  capture.hide();
}

function draw() {
  background(20);
  image(capture, 0, 0, 320, 240);
  filter(INVERT);
}

This puts up a grayscale video of what the camera is seeing.
However, it does not work on the jetson nano. All i see is a blank.

My camera on the nano is working fine.
This puts up a huge viewer that shows a live stream of what the camera sees

gst-launch-1.0 nvarguscamerasrc ! nvoverlaysink

When I run the code and look in the console , it shows this comment
p5.js says: createCapture() was expecting Function for parameter #1 (zero-based index), received an empty variable instead.

So clearly, the constant, VIDEO, is not pointing to the the video stream.
I tried replacing VIDEO with nvarguscamerasrc but the console says this is an undefined variable.

I looked in the file, p5.js, and found many classes of objects that use the constant, VIDEO.
The constant is defined in a separate file that is part of p5.js and is named p5.dom.js.
p5.prototype.VIDEO = 'video';
However, I cannot determine how VIDEO finds the proper hardware. nor do I know how to tell p5.js to look for the camera on the nano.

Can anyone shed light on this?
