C# 在asp.net应用程序中使用ffmpeg查找水印路径时出错

谁能帮我把watermark.png文件放在哪里，这样脚本就可以访问它。对于你的问题，我不知道你到底是如何执行ffmpeg的，因为你没有发布相应的代码，所以我会更笼统地回答 当您通过相对路径（
watermark.png- 或者让您的代码为子流程设置正确的工作目录
- 或者按绝对路径引用文件。但是请注意，您可能需要多次转义路径和命令行的其余部分（例如“\”或空格）

哦，还有，阿维当然有水印 我正在使用绝对路径作为输入、输出、预设等路径，但绝对路径也找不到水印图像的正确位置当前工作目录返回“c:\windows\system32\inetsrv”尝试执行水印命令并查看作为输出接收的内容。确定，我将尝试自己做一个SSCCE。@irfanmcsd完整示例已到达。请提供实际代码：@nmaier我发布了完整的代码。不，您只发布了部分代码。实际上运行这些东西的代码根本不存在（
