# useMediaControls

Reactive media controls for both `audio` and `video` elements

## Usage

### Basic Usage

```vue
<script setup lang="ts">
import { useMediaControls } from '@vueuse/core'
import { onMounted, useTemplateRef } from 'vue'

const video = useTemplateRef('video')
const { playing, currentTime, duration, volume } = useMediaControls(video, {
  src: 'video.mp4',
})

// Change initial media properties
onMounted(() => {
  volume.value = 0.5
  currentTime.value = 60
})
</script>

<template>
  <video ref="video" />
  <button @click="playing = !playing">
    Play / Pause
  </button>
  <span>{{ currentTime }} / {{ duration }}</span>
</template>
```

### 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
<script setup lang="ts">
import { useMediaControls } from '@vueuse/core'
import { useTemplateRef } from 'vue'

const video = useTemplateRef('video')
const {
  tracks,
  enableTrack
} = useMediaControls(video, {
  src: 'video.mp4',
  tracks: [
    {
      default: true,
      src: './subtitles.vtt',
      kind: 'subtitles',
      label: 'English',
      srcLang: 'en',
    },
  ]
})
</script>

<template>
  <video ref="video" />
  <button v-for="track in tracks" :key="track.id" @click="enableTrack(track)">
    {{ track.label }}
  </button>
</template>
```
