uniapp 上传视频到阿里云之后回显视频获取视频封面
官网的解决方案
1.initial-time Number 指定视频初始播放位置，单位为秒（s）。 没什么卵用
2.使用 uni.createVideoContext(“myVideo”, this).seek(number)。 没什么卵用
<video :id="myVideo"></video>
this.videoContext = uni.createVideoContext("myVideo", this)
this.videoContext.seek(1)
正确的解决方法
t_1000 等于截取视频第 1秒作为封面文章来源：https://www.toymoban.com/news/detail-847400.html
<video class="preview-file" :src="item1" :poster="item1 +'?x-oss-process=video/snapshot,t_1000,f_jpg'"></video>
