Getting Started

Setup

Install the camerakit package.

$ npm install camerakit

Usage

Import and use camerakit in your project.

import camerakit from "camerakit";

Or, alternatively, you can import via a script tag:

<script src="path/to/camerakit.min.js"></script>
<!-- You can now access `camerakit` from the global scope -->

For additional Safari requirements, see Safari support details.

Example usage:

async function () {
  const devices = await camerakit.getDevices();

  const preview = await camerakit.createCaptureStream({
    audio: devices.audio[0],
    video: devices.video[0]
  });

  preview.setResolution({width: 1920, height: 1080});
  const myPicture = preview.shutter.capture();

  preview.recorder.start();

  // Wait...

  // Pause the recording & resume
  await preview.recorder.pause();
  await preview.recorder.start();

  // Wait some more...

  const recordedVideo = await preview.recorder.stop(); // Use the video yourself

  preview.recorder.downloadLatestRecording(); // Download the video direct from browser

  // Stop using camera
  preview.destroy();

  // Play video via camerakit player
  const player = new camerakit.Player();
  player.src = window.URL.createObjectURL(recordedVideo);

  // Use the video player wherever you want!
  document.getElementById("your-player-container").appendChild(player);
  player.play();
}

Safari support details

Currently, the WebAssembly and JS worker files used for video recording and playback on Safari must be hosted seperately on a webserver. The compiled files can be found in dist/browser/, ensure they're accessible via a public URL (e.g https://myurl.com/myWorkerFile.js).

If you'd like to host the wasm/worker files in a custom path, you'll need to update the base param on camerakit.Loader and as well as to fallbackConfig when calling createCaptureStream:

import camerakit from "camerakit";

async function () {
  // Point fallback video player to correct directory
  camerakit.Loader.base = "/webm";

  const myStream = await camerakit.createCaptureStream({
    video: ...,
    audio: ...,
    fallbackConfig: {
      base: "/webm" // Point fallback recorder
    }
  });
}

Properties

Shutter

Instance methods

Recorder

Used for recording video of the the CaptureStream.

Instance methods

Player

A player following the HTMLVideoElement spec. Reccomended for playback as it can serve as a fallback for browsers that don't natively support webm.

Example:

const player = new camerakit.Player();

player.src = window.URL.createObjectURL(/* Your video Blob */);

player.play();
player.pause();
player.muted = true;
player.width = 1920;
player.height = 1080;

// Restart video playback
player.stop();
player.currentTime = 0;
player.play();

NOTE: If your browser supports the exported video, creating a Player instance will return a vanilla HTMLVideoElement.

Loader

Exposed OGVLoader.

FallbackConfig

NOTE: All fields are optional:

{
  base: string; // Base directory for wasm/worker files

  width: number;
  height: number;
  bitrate: number;
  framerate: number;
}
