Usage

Basic Usage

vue

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

const video = ref()
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 { ref } from 'vue'
const video = ref()
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>
