Examples

Multiple Quality Sources

Provide multiple sources with resolution labels for quality switching.

<script>
  import { Video } from '@delightstack/components';
  import type { Source } from '@delightstack/components';

  const sources: Source[] = [
    { src: '/videos/demo-1080.mp4', type: 'video/mp4', size: 1080 },
    { src: '/videos/demo-720.mp4', type: 'video/mp4', size: 720 },
    { src: '/videos/demo-480.mp4', type: 'video/mp4', size: 480 },
  ];
</script>

<Video src={sources} poster="/videos/demo-poster.jpg" />

HLS Streaming

Point src at an .m3u8 playlist (or pass a source with type application/vnd.apple.mpegurl) and the player handles HLS automatically. Browsers with native HLS support (Safari, iOS) play it directly; everywhere else the player lazy-loads hls.js only when an HLS source is detected. The custom controls — including a manifest-driven quality menu with an Auto option — are used in both cases.

hls.js is an optional peer dependency. Install it for HLS support in non-Safari browsers:

pnpm add hls.js

<Video src="https://stream.example.com/playlist.m3u8" />

With Captions

Add subtitle or caption tracks.

<script>
  import { Video } from '@delightstack/components';
  import type { Track } from '@delightstack/components';

  const captions: Track[] = [
    { kind: 'subtitles', src: '/subs/en.vtt', srclang: 'en', label: 'English', default: true },
    { kind: 'subtitles', src: '/subs/es.vtt', srclang: 'es', label: 'Spanish' },
  ];
</script>

<Video src="/videos/lecture.mp4" {captions} />

Autoplay Muted

Auto-playing videos must be muted to comply with browser policies.

Autoplay requires muted ; browsers block autoplay-with-sound until the user interacts.

View code

<Video src="/videos/background.mp4" autoplay muted loop controls={false} />

Accessing the Player

Bind the native HTMLVideoElement for programmatic control.

<script>
  import { Video } from '@delightstack/components';

  let player = $state<HTMLVideoElement>();
</script>

<Video src="/videos/clip.mp4" bind:player onready={({ player: p }) => {
  console.log('Video ready, duration:', p.duration);
}} />

<button onclick={() => player?.play()}>Play</button>

Skeleton Loading

Use skeleton while the source is still being resolved (e.g. fetched async). It fills the player with a placeholder background, skeleton controls, and a shimmer sweep. Providing a src automatically disables the skeleton — so the shimmer never sits on top of a real poster or video.

View code

<script>
  import { Video } from '@delightstack/components';

  // no src yet → skeleton; set it once it resolves
  let src = $state('');
</script>

<Video {src} skeleton={!src} />
