由于工作关系，需要不定时在阿里云上传视频文件，为了更加简化操作提升效率，结合WPF及阿里云SDK写了一个视频预览、截图、视频翻转以及本地视频上传并获取上传后视频的ImgUrl和videoUrl等关键播放参数的小工具
由于SDK中没有提供C#版的本地上传视频SDK，本人也不熟悉C++ ，只能从提供的JavaScriptDemo中，简单修改了个上传视频的页面，以下为正题：
js文档层级关系
lib
|---jquery.min.js
|---aliyun-upload-sdk
|-----aliyun-upload-sdk-1.5.0.min.js
|-----lib
|-----es6-promise.min.js

以下为页面运行截图：
其中：阿里云账号ID可在阿里云后台看到。其余视频ID、上传凭证、上传地址可从服务器端通过调用相关SDK，获取参数值
界面只是简单对必要参数做了微调，其余均为官网demo代码
