Combine audio and video files with FFMPEG in C#

I'm currently trying to combine two files, one audio, and one video, in my C# program using FFMPEG with the following code:

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = false;
startInfo.FileName = "ffmpeg.exe";
startInfo.Arguments = "ffmpeg -i video.mp4 -i mic.wav -c:v copy -map 0:v:0 -map 1:a:0 -c:a aac -b:a 192k output.mp4";
using (Process exeProcess = Process.Start(startInfo))
{
    exeProcess.WaitForExit();
}

My debug folder is set up like this: enter image description here

So I don't get any runtime errors, however, it just doesn't create the final output.mp4 file that I need it to.

I ended up solving it by doing the following:

string args = "/c ffmpeg -i \"video.mp4\" -i \"mic.wav\" -shortest outPutFile.mp4";
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.CreateNoWindow = false;
startInfo.FileName = "cmd.exe";
startInfo.WorkingDirectory = @"" + outputPath;
startInfo.Arguments = args;
using Process exeProcess = Process.Start(startInfo)

exeProcess.WaitForExit();
