Cloudflare Stream Player -- Customization and API

In this tutorial, you'll learn about Cloudflare Stream Player. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.

This tutorial covers how to customize the Cloudflare Stream player using skin properties, JavaScript API methods, and event listeners to build a tailored video playback experience for your application.

Why the Stream Player Matters

The default Cloudflare Stream player works out of the box, but most applications require custom branding, specific controls, and integration with analytics or advertising systems. The Stream player exposes a rich JavaScript API that lets you control playback programmatically, listen for events, change styles, and integrate with third-party services. This flexibility makes it suitable for everything from simple video pages to complex video platforms.

Real-world use: DodaZIP uses the Stream player API to track user engagement with tutorial videos. Custom events send play, pause, and completion data to an analytics pipeline, helping the team identify which tutorials retain viewers and which need improvement.

Basic Player Embed with Custom Skin

The Stream player accepts skin properties that control colors, fonts, and control bar visibility. These properties are passed as query parameters when embedding the player.

<!-- Customized Stream player with branded colors -->
<iframe
  src="https://customer-ABCDE.cloudflarestream.com/abc123/iframe?skinColor=%23ff6600&
         primaryColor=%23ff6600&textColor=%23ffffff&controls=%5B%22play%22%2C%22fullscreen%22%5D"
  style="border:none;width:640px;height:360px"
  allow="accelerometer; gyroscope; autoplay; encrypted-media; picture-in-picture"
  allowfullscreen>
</iframe>

The skin parameters above set the accent color to orange (#ff6600) and limit controls to play and fullscreen buttons. You can customize virtually every visual aspect of the player.

JavaScript Player API

For deeper integration, use the Stream player JavaScript SDK. It gives you programmatic control over playback, events, and state.

// Initialize the Stream player with JavaScript
const player = Stream(document.getElementById('my-player'), {
  src: 'abc123',
  autoplay: true,
  controls: true,
  muted: false,
});

// Control playback via API methods
player.play();
player.pause();
player.setCurrentTime(30); // Seek to 30 seconds
player.setVolume(0.8);     // Set volume to 80%

// Expected: player starts at 30 seconds with 80% volume

The SDK exposes methods for play, pause, seek, volume control, quality selection, and fullscreen toggling. Every method returns the player instance for chaining.

Listening to Player Events

The player fires events throughout the playback lifecycle. You can listen to these events to trigger custom behavior like analytics tracking or UI updates.

// Track viewer engagement with Stream player events
const player = Stream(document.getElementById('my-player'), { src: 'abc123' });

player.addEventListener('play', () => {
  console.log('Video started at', player.getCurrentTime());
  // Expected: "Video started at 0"
});

player.addEventListener('timeupdate', () => {
  const progress = (player.getCurrentTime() / player.getDuration()) * 100;
  if (progress > 25 && !tracked25) {
    sendAnalytics('watched_25_percent');
    tracked25 = true;
  }
  // Expected: analytics event sent once at 25% progress
});

player.addEventListener('ended', () => {
  sendAnalytics('video_completed');
  showNextVideoSuggestion();
  // Expected: analytics event sent on completion, next video shown
});

Common events include play, pause, timeupdate, ended, error, seeking, seeked, and fullscreenchange. Use these to build engagement tracking, advertising triggers, and custom overlays.
