[prasad deshpand]

Hi,

I am trying to upload video on website for that the thumbnail should be created automatically. But when i upload the video the error occurs "No process is associated with this object."

The code is as follows:

Guid id = Guid.NewGuid();
 
#region Upload the Video                           
 
Upload.SaveAs(Server.MapPath(VideoDir + id.ToString() + ".wmv"));
 
#endregion
 
#region Create the thumbnail
 
   string thumbpath, thumbname, inputfile;
   string thumbargs;
   Process thumbproc = new Process();
   try
   {      
      thumbpath = Server.MapPath(PictureDir);
      thumbname = thumbpath + id + ".jpg";
      inputfile = Server.MapPath(VideoDir + id.ToString() + ".wmv");
      thumbargs = "-i " + inputfile + " -f mjpeg -t 0.01 -y " + thumbname;
      thumbproc = new Process();
      thumbproc.StartInfo.FileName = Server.MapPath(".") + "\\ffmpeg\\ffplay.exe";
      thumbproc.StartInfo.Arguments = thumbargs;
      thumbproc.StartInfo.UseShellExecute = false;
      thumbproc.StartInfo.CreateNoWindow = true;
      thumbproc.StartInfo.RedirectStandardOutput = true;
      thumbproc.Start();
   }
   catch (Exception ex)
   {
       lblMessage.Text = ex.Message;
       lblMessage.ForeColor = System.Drawing.Color.Red;
       lblMessage.Visible = true;
   }
   if (thumbproc != null)
   {
       thumbproc.WaitForExit();
       thumbproc.Close();
    }
