因油管河蟹，及不慎手抽而痛失收藏视频，遂慌，借PowerShell bbenc工程代码而凑此物. （文言文太差，尽力了）

使用前，要在设置-->更新和安全-->开发者选项中解除PowerShell的运行限制，如图：

代码如下，拷下来用Unicode/UTF-8编码保存为yt-dlp-ops.ps1运行即可(⊙_◎)：

工作以及使用流程

1. 下载一个yt-dlp.exe工具
   • 最好创建一个文件夹用于放置
2. 打开一个记事本/空白文本文档进程
3. 将所有要下载的视频链接（取决于yt-dlp支持的视频网站）粘贴进去
   • 最好去掉如&list，&si之类的后缀，以防止油管未来在链接中用这种方式偷偷添加标记（可能想多了）
   • 可以用批量拷贝链接的浏览器插件，如Snap Links Plus
4. 创建一个文件夹用于下载所有视频
5. 运行yt-dlp-ops.ps1，可以在PowerShell ISE中打开并运行，也可以右键→用PowerShell运行
   • 将所有要下载的视频链接粘贴进去
   • 通过弹出的选择窗选择下载视频的路径
   • 通过弹出的选择窗定位yt-dlp.exe
   • 通过弹出的选择窗选择导出批处理的路径
   • 每天第一次使用时，选择y以添加一行用于导出当前浏览器cookie的命令
     • 用于以你的账号登录油管或其它视频网站，从而确保下载进程正常
   • 完成！双击运行导出的yt-dlp-download.bat以开始下载

其它特性

• 每个下载线程之间会随机生成一个1~7秒的间隔，从而让下载进程更像正常观看，且每次都不会重复
• 通过GUI窗口选择各种路径，极大地降低了操作难度
• 导出UTF-8 No BOM编码的批处理

那么就这样~

打赏信息

这玩意不一定适合打赏

• 更新2：添加了高DPI的Windows Form GUI选择窗渲染，添加了运行后暂停
• 更新3：添加了极为先进的分辨率自适应多行文本输入框Windows Form GUI，用于改进输入并编辑多链接的流程
• 更新4：添加了区分PowerShell ISE和Console窗口的区分，以正确统计分辨率
• 更新5：通过文本框Font属性搭配加载默认Windows Form并获取其中属性的方式实现了高DPI文本框字号过小的修复
• 更新6：通过属性设定的方式让说明直接出现在弹出的Windows Form窗口上，从而将操作流畅度增加了80%
