Capture/ Record The Desktop To Video File

Small command line using ffmpeg.exe to capture/recorde the desktop into a video file. In a command prompt window just type,

ffmpeg -f gdigrab -framerate 24 -i desktop -preset ultrafast -pix_fmt yuv420p out.mp4

Simple as that. The directory where the ffmpeg.exe is sitting this is where the mp4 video file will be created. This was a sample using it with the ffmpeg.exe in a command prompt window.

This is how to use it in c# in this case in visual studio 2013 express.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Diagnostics;

namespace Ffmpeg_App
{
    class Ffmpeg
    {
        Process process;

        public void Start(string FileName, int Framerate)
        {
            process = new System.Diagnostics.Process();
            process.StartInfo.FileName = @"D:\ffmpegx86\ffmpeg.exe"; // Change the directory where ffmpeg.exe is.
            process.EnableRaisingEvents = false;
            process.StartInfo.WorkingDirectory = @"D:\ffmpegx86"; // The output directory
            process.StartInfo.Arguments = @"-f gdigrab -framerate " + Framerate + " -i desktop -preset ultrafast -                                                                     pix_fmt yuv420p " + FileName;
            process.Start();
            process.StartInfo.UseShellExecute = false;
            process.StartInfo.CreateNoWindow = false;
            Close();
        }

        public void Close()
        {
            process.Close();
        }
    }
}

And this is how to use it in Form1,

In top of form1,

Ffmpeg fpeg = new Ffmpeg();

Button click event to start,

private void Start_Click(object sender, EventArgs e)
        {
            fpeg.Start("test.mp4", 24);
        }

Button click event to stop,

private void Stop_Click(object sender, EventArgs e)
        {
            fpeg.Close();
        }
