move ffmpeg.exe to bin\debug folder and try this code... using System.Diagnostics; using System.IO; public void exec(string input string output string parametri) { try { Process ffmpeg = new Process(); ffmpeg.StartInfo.FileName = Path.GetDirectoryName(Application.ExecutablePath) + @\utils\ffmpeg.exe; ffmpeg.StartInfo.Arguments =  -i  + input + (parametri != null ?   + parametri : ) +   + output; ffmpeg.StartInfo.UseShellExecute = false; ffmpeg.StartInfo.RedirectStandardOutput = false; ffmpeg.StartInfo.RedirectStandardError = true; ffmpeg.StartInfo.CreateNoWindow = false; ffmpeg.Start(); ffmpeg.WaitForExit(); ffmpeg.Close(); } catch (Exception ex) { throw; } } private void Form1_Load(object sender EventArgs e) { exec(G://1.mp4 G://1.flv -b 64k); }
