如何使用 cmd 或 PowerShell 脚本捕获/记录/下载多个流音频 URL？

Question 1

Windows 10 64 位。不需要管理员权限。

如何使用 streamripper v1.64.6 通过 cmd 或 PowerShell 脚本捕获/录制/下载多个流音频 URL，睡觉、PowerShell 5.1（System.Net.WebClient DownloadFileAsync)、curl v.7.55.1 和 ffmpeg v.3.4。音频流有多种提供方式，依赖一种方法来捕获并不是一个好主意。

我在使用 cmd 时取得了很大的成功，溪流撕裂者v.1.64.6和ffmpeg v.3.4。

Stop-process 用于终止 ffmpeg 和 curl 将下载内容写入文件。

您可以在使用 Windows Media Player 下载流媒体的同时收听流媒体。元数据长度并不总是能正确显示。

ffmpeg 可用于进行许多后期处理，例如写入元数据和修剪。将路径更改为 ffmpeg 和 curl。streamripper、System.Net.WebClient 和 curl 默认覆盖。我将 ffmpeg 设置为覆盖。

这些脚本下载需要 30 秒。

使用 cmd、streamripper 和 ffmpeg：当 streamripper 失去连接时，它会重命名原始文件并再次开始捕获。此批处理将文件连接起来。Streamripper 将至少捕获 iheart、tunein、streamguys、streamtheworld、radiojar、abacast 和 limelight 流。像往常一样编写命令以start "" streamripper.exe.lnk防止暂停。

流 URL 会发生变化。我写了一个页面，可帮助您查找流 URL。如何找到 iheart 流 url。
