Question

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();

I tried another way as shown below. But that is also won’t works.

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

Please help me with sample code for converting one video file format to another using ffmpeg in c# asp.net. Thanks in advance.

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");

Or:

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