HI Suthish
Happy New Year Firstly.
I tried your code and made some changes also. Now the code is executing ok but i;m not able to get the frame in my output file path. What may be the cause.

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");
        }
