vue简单实现移动端视频

  • Post author:
  • Post category:vue


描述：

  • 视频详情页以及全屏展示
  • 视屏详情包括：①提示视频大小，主义流量消耗；②视频右侧下方展示播放量按钮，分享按钮，全屏按钮；③视频正下方展示标题；④图标切换：视频开始按钮、进度条、上一个及下一个视频、全屏按钮；⑤背景毛玻璃样式(暂时先不考虑)
  • 全屏同视频详情，区别：标题在视频上方

思路：

放弃使用插件，采用video标签形式，注掉原生样式。

视屏详情：

  • 页面静态模块（按钮文字等），通过绝对定位实现；
  • 观看次数：后端数据；视频大小提醒及标题等：定位和后端数据；
  • 上下视频切换：点击按钮调接口返回的src；
  • 全屏按钮：隐藏原生video自带的全屏按钮，实现思路有两种：①通过插件screenfull实现，操作简单；②通过动态更改video标签宽高的方式实现，以下分两种情况：i：手机设置竖屏锁定，则此时要实现全屏则须旋转video90°，同时设置视频宽高；ii：手机未设置竖屏锁定，需要监测手机是否横屏，竖屏时同上一条处理，横屏时则无需旋转，改变宽高即可

全屏：

设置video标签的默认样式 – Rachid – 博客园

全屏按钮（插件实现）：

1.安装依赖 

 npm install --save screenfull

2.在需要设置的页面导入 

import screenfull from "screenfull";

3.实现 

<template>
    <div class="video">
        <video
            :src="src"
            ref="video"
            :width="width" :height="height"
            controls="controls"
            controlslist="nodownload nofullscreen noremoteplayback"
            :disablePictureInPicture="true"
            :poster="poster"></video>
        <div class="btn">
            <div class="aaa"></div>
            <div class="bbb"></div>
            <img :src="img" alt="" class="img4" @click="screenfull">
        </div>
    </div>
</template>
<script>
import screenfull from 'screenfull'
export default{
    data(){
        return{
            src: 'https://cdn.theguardian.tv/webM/2015/07/20/150716YesMen_synd_768k_vp8.webm',
            poster:require("@/assets/img/logo.png"),
            width: '100%',
            height:'100%',
            img: require("@/assets/img/4.png")
        }
    },
    methods:{
        //  全屏事件
        screenfull() {
            screenfull.toggle();
            console.log(screenfull)
        }
    }
}
</script>
<style lang="less" scoped>
/*video默认aduio音量按钮*/
video::-webkit-media-controls-mute-button { display: none !important;}
/*video默认setting按钮*/
video::-internal-media-controls-overflow-button{ display: none !important;}
video::-webkit-media-controls-fullscreen-button {
    display: none;
}
.video{
    width: 100vw;
    height: 100vh;
}
.btn{
    .aaa{
        z-index: 9999;
        width: 50px;
        height: 50px;
        background: red;
        position: absolute;
        right: 0;
        top: 100px;
    }
    .bbb{
        // z-index: 9999;
        width: 50px;
        height: 50px;
        background: blue;
        position: absolute;
        right: 0;
        top: 300px;
    }
    .img4{
        z-index: 9999;
        width: 50px;
        height: 50px;
        position: absolute;
        border: 1px solid red;
        right: 0;
        bottom: 100px;
        background: blue;
    }
}
</style>

4.效果(原理实现，样式没改丑了点，小声bb)


毛玻璃

.video{
    width: 100vw;
    height: 100vh;
    // background: #000;
    background: url('../../assets/img/bg9.png') no-repeat;
    background-size:  100% 100%;
}

播放按钮

将播放按钮图片定位到合适位置，然后调用video的相关接口 

<div class="notice">
    <img src="@/assets/img/2.png" alt="" class="img2" @click="play">
     <div>
         <div>当前视频大小365M</div>
         <div>如您使用移动网络，请注意流量消耗~</div>
      </div>
 </div>


.notice{
    position: absolute;
    z-index: 9999;
    left: 30vw;
    top: 50vh;
    font-size: 16px;
    margin-left: -50px;
    margin-top: -20px;
    display: flex;
    flex-direction: column;
    align-items: center;
    color: #fff;
    .img2{
        width: 50px;
        height: 50px;
    }
}



play() {
            var video = document.getElementById('video');
            console.log(video.currentTime,video.paused)
            // 判断视频当前状态是 暂停/播放
            if(video.paused){
                video.play()
            }else{
                video.pause()
            }
        }
