Tracks the current stream delivery type so components can toggle live-specific UI (a live indicator, "jump to live edge" affordance, hiding the time display, etc.).

When the media exposes its own `streamType` (e.g. HLS sources derive it from the manifest), the feature syncs on `streamtypechange`. For plain media elements without that capability, it falls back to duration-based detection: an infinite `duration` reports `'live'`, a finite positive `duration` reports `'on-demand'`, and anything else reports `'unknown'`.

<FeatureReference feature="streamType" />

### Selector

<FrameworkCase frameworks={["react"]}>
Pass `selectStreamType` to <DocsLink slug="reference/use-player">`usePlayer`</DocsLink> to subscribe to stream type state. Returns `undefined` if the stream type feature is not configured.
</FrameworkCase>

<FrameworkCase frameworks={["html"]}>
Pass `selectStreamType` to <DocsLink slug="reference/player-controller">`PlayerController`</DocsLink> to subscribe to stream type state. Returns `undefined` if the stream type feature is not configured.
</FrameworkCase>

<FrameworkCase frameworks={["react"]}>
```tsx title="LiveIndicator.tsx"
import { selectStreamType, usePlayer } from '@videojs/react';

function LiveIndicator() {
  const stream = usePlayer(selectStreamType);
  if (stream?.streamType !== 'live') return null;

  return <span className="live-indicator">LIVE</span>;
}
```
</FrameworkCase>

<FrameworkCase frameworks={["html"]}>
```ts title="live-indicator.ts"
import { createPlayer, MediaElement, selectStreamType } from '@videojs/html';
import { videoFeatures } from '@videojs/html/video';

const { PlayerController, context } = createPlayer({ features: videoFeatures });

class LiveIndicator extends MediaElement {
  readonly #stream = new PlayerController(this, context, selectStreamType);
}
```
</FrameworkCase>
