篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了uni-app 视频播放遇到的问题-video相关的知识，希望对你有一定的参考价值。
最近开发一个项目，一个视频列表，点击其中一个视频，全屏播放（像大屏预览似的全屏），图上覆盖截图，全屏和回放图标。
本文涉及到的知识点：
1。视频播放video组件使用；
2。图片下载uni.downloadFile；
3。上拉加载，下拉刷新
4。subNVue；
5。父子组件传值
弹出的全屏窗口：
videoTest.vue
<template>

this.src = params.path;
this.picPath = params.picPath;

if(this.playStatus == 1)
this.videoContext.requestFullScreen();

changeFull(params)
console.log('changeFull',params);
if(params.detail.fullScreen)
//不能动态设置进度条的显示
// this.videoContext.controls = true;
else
plus.screen.lockOrientation('portrait-primary');
//屏幕方向数值： 0 - 竖屏； 90 - 横屏，HOME键在右； 180 - 反向竖屏； -90 - 反向横屏，HOME'键在左
// let orit = plus.navigator.getOrientation();

]视频列表页：
列表中做了两种处理：
1。有视频时显示视频，并显示封面，但点击视频时，并不触发播放，是弹出全屏页面，在全屏页面进行全屏，截图等操作；这种处理需要用subNVue特殊处理一下弹出框，要不然弹出框会被视频遮挡。
2。另一种处理是不管有没有视频，都显示图片，有视频的图片给它显示播放按钮和截屏按钮，但点击图片时，仍然会弹出全屏页面。被注释掉的代码就是只显示图片的处理。

（1）subNVue弹窗的显示，只能使用js的show方法，无法携带参数。
（2）参数传递使用uni.$emit和uni.$on

参考技术A <video id="video_play" :src="videosrc" @play="playVedio()" ></video>playVedio()
// 获取 video 上下文 videoContext 对象
this.videoContext = uni.createVideoContext('video_play');
// 进入全屏状态
this.videoContext.requestFullScreen();
