## Installation

<CodeGroup>
  ```bash npm theme={null}
  npx @beyondwords/cli components add playback-rate-button
  ```

  ```bash pnpm theme={null}
  pnpm dlx @beyondwords/cli components add playback-rate-button
  ```

  ```bash yarn theme={null}
  yarn dlx @beyondwords/cli components add playback-rate-button
  ```

  ```bash bun theme={null}
  bunx --bun @beyondwords/cli components add playback-rate-button
  ```
</CodeGroup>

## Usage

```tsx theme={null}
import { PlayerProvider } from '@/registry/react/PlayerProvider';
import { PlaybackRateButton } from '@/registry/react/PlaybackRateButton';

export function Player() {
  return (
    <PlayerProvider args={{ projectId: 9504, contentId: "ba00ef51-03ac-4a85-8b98-e45c957e8ef8", showUserInterface: false }}>
      <PlaybackRateButton />
    </PlayerProvider>
  );
}
```

The button reads `playbackRate` from the surrounding
[`PlayerProvider`](/player-ui/react/player-provider). On click, it sets
`player.playbackRate` directly on the instance, toggling between `1` and
`1.5`. The current rate renders as the label (e.g. `1x`). Adjust the toggle
logic to expose whatever speeds you want.
