# p5.videorecorder

p5.videorecorder is a small [p5js](https://p5js.org) add-on for recording video from sketches using the [MediaRecorder api](https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder). The library adds a p5.VideoRecorder class.

## Getting Started

Download the latest release from the [releases page](https://github.com/calebfoss/p5.videorecorder/releases).

Put p5.videorecorder.js in the same directory as your sketch. If using the [web editor](https://editor.p5js.org), you will need to [upload the file](https://thecodingtrain.com/beginners/p5js/6.4-files-web-editor.html).

Add p5.videorecorder.js to your sketch's index.html file in a script tag:

```
<!doctype html>
<html>
<head>
  <script src="p5.js"></script>
  <script src="p5.sound.js"></script>
  <script src="p5.videorecorder.js></script>
  <script src="sketch.js"></script>
</head>
<body>
</body>
</html>

```

Create a new instance of the the p5.VideoRecorder class in your sketch.js file.

```
let videoRecorder;

function setup() {
  createCanvas(400, 400);
  videoRecorder = new p5.VideoRecorder();
}
```

See [Examples](https://github.com/calebfoss/p5.videorecorder#examples) and [Reference](https://github.com/calebfoss/p5.videorecorder#reference) for usage.

## Examples

- [simple canvas](https://editor.p5js.org/cfoss/sketches/t6H_m8AeR)
- [canvas with sound](https://editor.p5js.org/cfoss/sketches/yYxZHMcI1)
- [webcam](https://editor.p5js.org/cfoss/sketches/5SSZyFsEN)

## Reference

### p5.VideoRecorder

#### Description

Class for recording video from the sketch. If no arguments are passed into the constructor, the VideoRecorder instance will default to record the canvas as well as all [p5.sound](https://p5js.org/reference/#/libraries/p5.sound) audio output (if [p5.sound](https://p5js.org/reference/#/libraries/p5.sound) library has been loaded).

The recorded video file may not be available immediately after the stop() method is called. Set the onFileReady callback to call a function when the recorder has finished creating the video file.

Ability to record inputs may vary based on the browser. Recording the canvas is supported by most contemporary browsers (see [browser compatibility](https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/captureStream#browser_compatibility)), but recording media elements currently has limited support (see [browser compatibility](https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/captureStream#browser_compatibility)). You can check whether an object can be recorded by passing it into the canRecord() method (see [Reference](https://github.com/calebfoss/p5.videorecorder#methods)).
