• Playback Speed: Choose from multiple playback speeds (0.5x, 0.75x, 1x, 1.25x, 1.5x, 2x) via a settings menu.
• Captions Toggle: Enable/disable placeholder captions (extendable with WebVTT for real captions).
• Loading Spinner: Visual feedback during video buffering.
• Responsive Design: Adapts to different screen sizes, with adjustments for mobile devices.
• Modern Styling: Clean, minimalistic UI with hover effects, custom colors, and smooth transitions.

• Play/Pause: Click the play button (▶/❚❚) or the video itself to toggle playback.
• Seek: Click or drag the progress bar to jump to a specific time. Hover over the progress bar to see a time preview.
• Volume: Use the volume slider to adjust audio levels or click the mute button (🔊/🔇) to toggle mute.

• Playback Speed: Click the settings button (⚙️) to open the menu and select a playback speed.
• Captions: Click the captions button (CC) to toggle placeholder captions (extend with WebVTT for actual subtitles).
• Responsive Behavior: The player adjusts its layout and control sizes for smaller screens.

• Video Source: Update the <source> tag in the <video> element to use your own video file.
• Styling: Modify CSS variables in the :root section (e.g., --primary-color, --bg-color) to change the color scheme.
• Captions: To add real captions, include a WebVTT file and add a <track> element to the <video> tag, e.g.:

  <track src="captions.vtt" kind="subtitles" srclang="en" label="English">

• Poster Image: Replace the poster attribute in the <video> tag with your own image URL for the video thumbnail.
• Additional Features: Extend the JavaScript to add features like keyboard shortcuts, quality selection, or custom controls.

• Dependencies: No external dependencies are required, as all styling and functionality are implemented with vanilla HTML, CSS, and JavaScript.
• Limitations:
  • The captions feature is a placeholder and requires a WebVTT file for full functionality.
  • Some browsers may restrict autoplay or fullscreen when not hosted on a server due to security policies.
• Debugging: Open the browser's developer tools (F12) to check the console for errors if any functionality doesn't work as expected.
• Video Source: The sample video (BigBuckBunny.mp4) is hosted externally. Ensure your video source is accessible and in a supported format.

• Controls Not Working: Ensure the video file is accessible and the browser supports HTML5 video. Check the console for errors.
• Fullscreen Issues: Some browsers require the page to be served over HTTP/HTTPS for fullscreen to work.
• Duration Display Errors: If the duration shows incorrectly, verify the video file's metadata is valid and the loadedmetadata event is firing.
• Performance: For large videos, ensure your server supports range requests to enable smooth seeking.
