# `useVideo`
Creates `<video>` element, tracks its state and exposes playback controls.
## Usage
```jsx
import {useVideo} from 'react-use';
const Demo = () => {
const [video, state, controls, ref] = useVideo(
<video src="http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4" autoPlay />
);
return (
<div>
{video}
<pre>{JSON.stringify(state, null, 2)}</pre>
<button onClick={controls.pause}>Pause</button>
<button onClick={controls.play}>Play</button>
<br/>
<button onClick={controls.mute}>Mute</button>
<button onClick={controls.unmute}>Un-mute</button>
<br/>
<button onClick={() => controls.volume(.1)}>Volume: 10%</button>
<button onClick={() => controls.volume(.5)}>Volume: 50%</button>
<button onClick={() => controls.volume(1)}>Volume: 100%</button>
<br/>
<button onClick={() => controls.seek(state.time - 5)}>-5 sec</button>
<button onClick={() => controls.seek(state.time + 5)}>+5 sec</button>
</div>
);
};
```
## Reference
```jsx
const [video, state, controls, ref] = useVideo(props);
const [video, state, controls, ref] = useVideo(<video {...props}/>);
```
`video` is React's `<video>` element that you have to insert somewhere in your
render tree, for example:
```jsx
<div>{video}</div>
```
`state` tracks the state of the video and has the following shape:
```json
{
"buffered": [
{
"start": 0,
"end": 425.952625
}
],
"time": 5.244996,
"duration": 425.952625,
"isPlaying": false,
"muted": false,
"volume": 1
}
```
`controls` is a list collection of methods that allow you to control the
playback of the video, it has the following interface:
```ts
interface AudioControls {
play: () => Promise<void> | void;
pause: () => void;
mute: () => void;
unmute: () => void;
volume: (volume: number) => void;
seek: (time: number) => void;
}
```
`ref` is a React reference to HTML `<video>` element, you can access the element by
`ref.current`, note that it may be `null`.
And finally, `props` &mdash; all props that `<video>` accepts.
