# useMediaControls
Reactive media controls for both `audio` and `video` elements
## Usage
### Basic Usage
```vue
{{ currentTime }} / {{ duration }}
```
### Providing Captions, Subtitles, etc...
You can provide captions, subtitles, etc in the `tracks` options of the
`useMediaControls` function. The function will return an array of tracks
along with two functions for controlling them, `enableTrack`, `disableTrack`, and `selectedTrack`.
Using these you can manage the currently selected track. `selectedTrack` will
be `-1` if there is no selected track.
```vue
```
