# MuxAudio

Audio element for Mux-hosted HLS streams

Audio element for playing Mux-hosted HLS streams. Built on hls.js with Mux-specific optimizations.

## Import

```bash
pnpm add @videojs/mux-audio
```

```tsx
import { MuxAudio } from '@videojs/react/media/mux-audio';
```

## Analytics and casting

The Mux audio component plays Mux streams. It doesn’t monitor them or cast them — [Mux Data](https://videojs.org/docs/framework/react/guides/mux-data) and [Google Cast](https://videojs.org/docs/framework/react/guides/casting) are separate extensions you add to the player alongside it. Mux Data needs no environment key here, since Mux attributes the views to the environment that owns the playback ID:

Install both extensions before using the example below:

```bash
pnpm add @videojs/mux-data @videojs/google-cast
```

```tsx
import { GoogleCast } from '@videojs/react/extensions/google-cast';
import { MuxAudio } from '@videojs/react/media/mux-audio';
import { MuxData } from '@videojs/react/extensions/mux-data';

<MuxAudio source={{ playbackId: 'BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM' }} />
<MuxData playerSoftwareName="mux-audio" />
<GoogleCast />
```

## Examples

### Basic Usage

**App.tsx**

```tsx
import { MuxAudio } from '@videojs/react/media/mux-audio';

export default function BasicUsage() {
  return <MuxAudio className="mux-audio" src="https://stream.mux.com/BV3YZtogl89mg9VcNBhhnHm02Y34zI1nlMuMQfAbl3dM.m3u8" crossOrigin="anonymous" controls />;
}
```

**App.css**

```css
.mux-audio {
  width: 100%;
  height: 54px;
}
```

## API Reference

### Props

Accepts the standard React props for a native `<audio>`, plus these Video.js-specific props:

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `disableRemotePlayback` | `unknown` | `false` | Whether remote playback (AirPlay, Google Cast) is disabled for this media. |
| `preload` | `MediaPreloadType` | `'metadata'` | Preload type (`'none'` / `'metadata'` / `'auto'`). |
| `source` | `{ type?: 'application/vnd.apple.mpegurl' \| 'video/mp4'; preferPlayback?: 'mse' \| 'native'; maxAutoResolution?: '270p' \| '360p' \| '480p' \| '540p' \| '720p' \| '1080p' \| '1440p' \| '2160p'; capRenditionToPlayerSize?: boolean; minAutoResolution?: '270p' \| '360p' \| '480p' \| '540p' \| '720p' \| '1080p' \| '1440p' \| '2160p'; engine?: HlsEngineConfig; src?: string; playbackId?: string; customDomain?: string; playback?: MuxPlaybackParams; poster?: MuxPosterParams; storyboard?: MuxStoryboardParams; drm?: MuxDrmParams } \| null` | `null` | Structured Mux source. Setting it derives `src` from the playback ID, custom domain, and `playback` params (appended as `snake_case` query params). A `playback.token` replaces all other params — signed URLs bake them into the token. Engine options live under `engine`. A `drm.token` fills in `drm` itself: Mux's FairPlay, Widevine, and PlayReady license servers for this playback ID, so protected media plays whichever path the browser takes. License servers named alongside the token win, key by key, for content Mux does not license. `playback.maxResolution` and `playback.minResolution` are server-side: they decide which renditions Mux puts in the manifest at all. The inherited `maxAutoResolution` and `minAutoResolution` only look like their pair — those are client-side and bound which of the renditions that *do* arrive adaptive selection reaches for. The two halves are independent. |
| `src` | `string` | `''` | Media source URL. Setting a Mux stream URL (`https://stream.mux.com/<playback-id>.m3u8?...`) extracts the playback ID and query params into `source`; other URLs are kept as a plain `source.src`. Only playback options carry over. Mux identity comes from the URL, and the signed `poster`, `storyboard`, and `drm` tokens are scoped to a playback ID, so carrying them onto a different source would build rejected URLs. |
| `streamType` | `'on-demand' \| 'live' \| 'unknown'` | `'unknown'` | Current stream type (`'on-demand'` / `'live'` / `'unknown'`). |

### Engine options

#### `source.engine.nativeHls`

Options passed under `source.engine.nativeHls`.

| Option | Type | Description |
| --- | --- | --- |
| `drmSystems` | `Partial<Record<KeySystem, DrmSystemConfig>> \| undefined` | License servers for protected content, keyed by EME key system id. An escape hatch for licensing native playback differently from every other path: naming it replaces `source.drm` here, and nowhere else. |

### Ref

Forwards its ref to the rendered `<audio>`. The ref is an [HTMLAudioElement](https://developer.mozilla.org/en-US/docs/Web/API/HTMLAudioElement) and exposes its complete native property and method API.

### Events

Handle standard media events with React event props such as `onPlay` and `onTimeUpdate`. For native events without a React prop, attach a listener through the ref with `addEventListener`.
