You can find information about releases here

• Operating system
  • macOS: 10.12 Sierra or newer (required to build Safari extension)
  • Windows: Vista or newer using Cygwin
  • Linux: 64-bit Ubuntu 14.04+, Debian 8+, openSUSE 13.3+, or Fedora Linux 24+
• Software
  • Node.js
  • Java (Windows only)

The following build tools are used to build the extension:

• csso for compressing CSS
• svgo for compressing SVG images
• xarjs for packaging Safari legacy extension
• google-closure-compiler for compiling JavaScript

These can be installed by executing the following command:

npm install -g csso-cli svgo xar-js google-closure-compiler

1. Clone the repository
2. Run make.sh
   1. By default this builds the unoptimized and unpackaged development version for all targets into the ./out/ directory
   2. Alternatively:
      • ./make.sh -p release to build the optimized release versions for all targets
      • ./make.sh -p release -t chrome to build the optimized release version for the Chrome browser
      • ./make.sh -h to see the full list of options

If we wanted to support example.com with the source:

<div class="video-container">
  <video src="blob:http://example.com/342b3a13-c892-54ec-84f6-281579de03ab"></video>
  <div class="video-captions">
    Example caption
  </div>
  <div class="video-controls">
    <button class="control button-play">Play</button>
    <button class="control button-fullscreen">Fullscreen</button>
  </div>
</div>

We would start by adding a new file example.js in the resources directory:

export const domain = 'example';

export const resource = {
  buttonParent: function() {
    // Returns the element that will contain the button
    return document.querySelector('.video-controls');
  },
  videoElement: function() {
    // Returns the video element
    return document.querySelector('.video-container video');
  },
  
  // Optional
  captionElement: function() {
    // Returns the element that contains the video captions
    return document.querySelector('.video-captions');
  },
};

We might want to style the button so that it integrates with the page better:

export const resource = {
  ...
  // Assign a CSS class
  buttonClassName: 'control',
  // Scale the button
  buttonScale: 0.5,
  // Apply custom CSS styles
  buttonStyle: /** CSS */ (`
    /* Declaring CSS this way ensures it gets optimized when the extension is built */
    cursor: pointer;
    opacity: 0.5;
  `),
  // Apply a custom CSS hover style
  buttonHoverStyle: /** CSS */ (`opacity: 1 !important`),
};
