  using System.Diagnostics;
  
  var inputArgs = "-framerate 20 -f rawvideo -pix_fmt rgb32 -video_size 1920x1080 -i -";
  var outputArgs = "-vcodec libx264 -crf 23 -pix_fmt yuv420p -preset ultrafast -r 20 out.mp4";
  
  var process = new Process
  {
      StartInfo =
      {
          FileName = "ffmpeg.exe",
          Arguments = $"{inputArgs} {outputArgs}",
          UseShellExecute = false,
          CreateNoWindow = true,
          RedirectStandardInput = true
      }
  };
  
  process.Start();
  
  var ffmpegIn = process.StandardInput.BaseStream;
  
  // Write Data
  ffmpegIn.Write(Data, Offset, Count);
  
  // After you are done
  ffmpegIn.Flush();
  ffmpegIn.Close();
  
  // Make sure ffmpeg has finished the work
  process.WaitForExit();
