C# 如何启用FFMPEG的不同组件？

我在FFMPEG附近发现了这个。我正在使用ASP.NET MVC3和C。在尝试使其工作时，我遇到以下错误：

我是FFMPEG的新手，所以我不知道从哪里开始解决上述问题

编辑

public ActionResult Convert()
    {
        Converter _converter = new Converter(@"C:\FfMpeg\ffmpeg.exe");
        OutputPackage oo = _converter.ConvertToFLV(@"C:\FfMpeg\Videos\Original\Video1.wmv");

        FileStream outStream = System.IO.File.OpenWrite(@"C:\FfMpeg\Videos\Converted\Video1.flv");
        oo.VideoStream.WriteTo(outStream);
        outStream.Flush();
        outStream.Close();

        oo.PreviewImage.Save(@"C:\FfMpeg\Videos\Thumbnail\Thumbnail1.jpg");

        return RedirectToAction("WatchMovie");
    }

感谢您的帮助

能否让ffmpeg输出更具可读性？用真正的换行符替换“\r\n”。@satuon，很抱歉，我暗示r/n/将被换行符替换。ffmpeg似乎无法打开输出文件进行写入。这可能是因为您没有写入目录的权限。在我看来，您尚未指定输出文件的完整路径，因此ffmpeg将尝试写入当前目录。尝试指定绝对文件路径。您还可以粘贴用于调用exe的命令行吗？@satuon:查看编辑。我试着用一种行动的方法。这样在转换之后，视频就会被观看。顺便说一下，问题的开头有一个链接指向示例代码的网页。
