如果uniapp打包成apk用于安卓的话 video标签不会跟随屏幕一起滑动，会固定在屏幕上并且层级过高会挡住其他元素所以需要一个iframe标签封装成组件

<template><iframe :onload="onloadCode" style="width:100%;height:100%;border:1px solid #fff;background: #000;"></iframe>
</template>
<script>javascript">
export default {props: {src: '',},data() {return {onloadCode: ''}},methods:{play(index) {let videoContext = uni.createVideoContext('videoId', this)videoContext.requestFullScreen()},//退出全屏时暂停fullscreenchange(e) {if (!e.detail.fullScreen) {uni.createVideoContext('videoId', this).pause();}},},created() {console.log(this.src)this.onloadCode =`this.contentWindow.document.body.innerHTML = '<video style="width: 100%;height: 100%"  controls :direction="90"  @play="play"  @fullscreenchange="fullscreenchange"  id="videoId"  src="${this.src}"></video>';`},
}
</script>
<style lang="scss">
</style>

外部引用的时候直接传入src

<nVideo v-if="tapIndex===2"  :src="imgUrl" class="nVideo"></nVideo>
