进程抛出System.InvalidOperationException [英] Process throws System.InvalidOperationException

问题描述

我正在将视频转换为.swf格式，并从该视频创建一个帧以用作缩略图。我面临的问题是该进程抛出了system.InvalidOperationException异常。我到处搜索，仍然无法解决这个问题......有人可以帮我解决一下如何解决这个问题....



这个就是我所做的：

I''m converting video''s to .swf format and creating a single frame from that video to use as a thumbnail. The problem that I am facing is that the process is throwing an exception of system.InvalidOperationException. I''ve searched everywhere and still can''t solve this... can somebody please help me out on how to fix this please....

this is what I have done:

filargs = "C:\\Program Files\\ffmpeg\\ffmpeg.exe -i " + inputfile + " -ar 22050 " + outputfile;

string spath;
spath = Server.MapPath(".");
ProcessStartInfo procStartIfo = new ProcessStartInfo();
procStartIfo.FileName = "C:\\Program Files\\ffmpeg\\ffmpeg.exe";
procStartIfo.Arguments = filargs;
procStartIfo.UseShellExecute = false;
procStartIfo.CreateNoWindow = false;
procStartIfo.RedirectStandardOutput = true;

try
{
    var process = new Process();

        process.StartInfo = procStartIfo;
        process.Start();
        process.WaitForExit();

}

推荐答案

您需要将路径放入双引号，因为有一个空间。另外，从文件标记中删除路径。

You need to put the path into double quotes because there is a space in it. Also, remove the path from your fileargs.
