  11 septembre 2012, par Lynx

  i want to pass the thumbnail generated by ffmpeg to save_FTPUpload where the save_FTPUpload function is to upload the image file to ftp server. how can i do that ?
  here is my example code for thumbnail generation using ffmpeg and "fileupload" function for uploading files to ftp server :

  public partial class testtttt : System.Web.UI.Page
  
  {
  
      protected void Page_Load(object sender, EventArgs e)
  
      {
  
          generateThumbnail();
  
          string fi_attachment = @"C:\2.jpg";//source image file
  
          save_FTPUpload(fi_attachment);
  
      }
  
  
  
      private void generateThumbnail()
  
      {
  
          string thumbpath, thumbname, videofile;
  
  
  
          videofile = "http://www.xxxx.com/video.Avi";
  
          thumbpath = @"C:\";
  
          thumbname = thumbpath + Path.GetFileNameWithoutExtension(videofile) + ".jpg";
  
  
  
          string thumbargs = "-i \"" + videofile + "\" -vframes 1 -s 60*30 -ss 00:00:00 -f image2 \"" + thumbname + "\"";
  
  
  
          Process process = new Process();
  
  
  
          process.StartInfo.FileName = Server.MapPath("~\\ffmpeg\\bin\\ffmpeg.exe");
  
          process.StartInfo.Arguments = thumbargs;
  
  
  
          process.StartInfo.UseShellExecute = false;
  
          process.StartInfo.RedirectStandardOutput = true;
  
          process.StartInfo.RedirectStandardInput = false;
  
          process.StartInfo.RedirectStandardError = true;
  
          process.StartInfo.CreateNoWindow = false;
  
          process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  
  
  
          try
  
          {
  
              process.Start();
  
              string output2 = process.StandardError.ReadToEnd();
  
              string output3 = process.StandardOutput.ReadToEnd();
  
  
  
              if (process != null)
  
              {
  
                  process.Close();
  
              }

          }

      public bool save_FTPUpload(string fi_attachment)
  
      {
  
          bool fileSaved = false;
  
          //string fi_attachment = @"C:\1.jpg";
  
          string filename = "3.jpg";//image name to be saved in ftp
  
          string ftp_user = "*****"; //username
  
          string ftp_pass = "*****"; //password
  
          string ftpURI = "ftp://www.xxxx.com/thumb/"; //ftp path where the image will be saved
  
  
  
          while (!fileSaved)
  
          {
