上的ProcessStartInfo ffmpeg的C＃asp.net帮助 [英] ffmpeg c# asp.net help on ProcessStartInfo

问题描述

我写了code使用的ffmpeg转换文件在c＃asp.net。虽然执行它会显示错误的文件名，目录名或卷标语法不正确，但我的路径是正确的。那么如何解决这个？

I wrote the code to convert the file in c#asp.net using ffmpeg. While executing it shows error as "The filename, directory name, or volume label syntax is incorrect" but my paths are correct. So what is the solution for this?

ProcessStartInfo info = new ProcessStartInfo("e:\ffmpeg\bin\ffmpeg.exe", "-i cars1.flv -same_quant intermediate1.mpg");

process.Start();

我尝试的另一种方法，如下所示。但是，这也不会工作。

ProcessStartInfo info = new ProcessStartInfo("ffmpeg.exe", "-i cars1.flv -same_quant intermediate1.mpg");

请帮我带样品code在C＃中asp.net一个视频文件格式转换为另一种使用的ffmpeg。先谢谢了。

推荐答案

反斜杠（ \\ ）被认为开始的转义序列的。以prevent这一点，无论是使用双反斜线（ \\\\ ）或preFIX字符串以 @ 。

The backslashes (\) in your path are considered to start escape sequences. To prevent this, either use double backslashes (\\), or prefix the string with @.

ProcessStartInfo info = new ProcessStartInfo("e:\\ffmpeg\\bin\\ffmpeg.exe", 
                         "-i cars1.flv -same_quant intermediate1.mpg");

或者

ProcessStartInfo info = new ProcessStartInfo(@"e:\ffmpeg\bin\ffmpeg.exe", 
                         "-i cars1.flv -same_quant intermediate1.mpg");
