Get Started#

Start fresh with a standalone Video Player project. This creates a complete, ready-to-run application.

Step 1: Clone the Repository#

Terminal
git clone https://github.com/imgly/starterkit-video-player-ts-web.git
git clone https://github.com/imgly/starterkit-video-player-ts-web.git

The src/ folder contains the player code:

src/
├── index.ts                      # Application entry point
└── imgly/
    ├── index.ts                  # Player initialization function
    └── config/
        ├── plugin.ts             # Main configuration plugin
        ├── features.ts           # Feature toggles
        ├── i18n.ts               # Translations
        ├── settings.ts           # Engine settings
        └── ui/                   # UI customization
            ├── index.ts          # Combines UI customization exports
            ├── canvas.ts         # Canvas configuration
            └── navigationBar.ts  # Navigation bar layout

Step 2: Install Dependencies#

Terminal
cd starterkit-video-player-ts-web
npm install
cd starterkit-video-player-ts-web
npm install

Step 3: Download Assets#

CE.SDK requires engine assets (fonts, icons, UI elements) to function. These must be served as static files from your project’s public/ directory.

Terminal
curl -O https://cdn.img.ly/packages/imgly/cesdk-js/1.69.0/imgly-assets.zip
unzip imgly-assets.zip -d public/
rm imgly-assets.zip
curl -O https://cdn.img.ly/packages/imgly/cesdk-js/1.69.0/imgly-assets.zip
unzip imgly-assets.zip -d public/
rm imgly-assets.zip

The baseURL in your configuration should point to this location:

src/index.ts
const config = {
  // ...
  baseURL: '/assets'
};

Step 4: Run the Development Server#

Terminal
npm run dev
npm run dev

Open http://localhost:5173 in your browser.

Set Up a Scene#

CE.SDK offers multiple ways to load content into the player. Choose the method that matches your use case:

src/index.ts
// Load from a template archive - loads a previously saved project
await cesdk.loadFromArchiveURL('https://example.com/video.zip');


// Load from a scene file - restores a scene from JSON
await cesdk.loadFromURL('https://example.com/scene.json');


// Zoom to fit the content
await cesdk.actions.run('zoom.toPage', {
  page: 'first',
  autoFit: true,
  padding: 24
});

Customize (Optional)#

Theming#

CE.SDK supports light and dark themes out of the box, plus automatic system preference detection. Switch between themes programmatically:

src/imgly/config/settings.ts
// 'light' | 'dark' | 'system' | (() => 'light' | 'dark')
cesdk.ui.setTheme('dark');

See Theming for custom color schemes, CSS variables, and advanced styling options.

Localization#

Customize UI labels and add support for multiple languages. The i18n system supports translation keys for all UI elements:

src/imgly/config/i18n.ts
// Override specific labels
cesdk.i18n.setTranslations({
  en: {
    'common.play': 'Play Video',
    'common.pause': 'Pause'
  }
});


// Add a new language
cesdk.i18n.setTranslations({
  de: {
    'common.play': 'Video abspielen'
  }
});


// Set the active locale
cesdk.i18n.setLocale('de');

See Localization for supported languages, translation key reference, and right-to-left language support.

Troubleshooting#

Player doesn’t load#

  • Check the container element exists: Ensure your container element is in the DOM before calling create()
  • Verify the baseURL: Assets must be accessible from the CDN or your self-hosted location
  • Check console errors: Look for CORS or network errors in browser developer tools

Content doesn’t appear#

  • Check network requests: Open DevTools Network tab and look for failed requests to cdn.img.ly
  • Self-host assets for production: See Serve Assets to host assets on your infrastructure

Video doesn’t play#

  • Check browser autoplay policies: Browsers require user interaction before playing video
  • Verify video format: Ensure video files are in a supported format (MP4, WebM)

Watermark appears in production#

  • Add your license key: Set the license property in your configuration
  • Sign up for a trial: Get a free trial license at img.ly/forms/free-trial
