• Open DivX/XVID videos in OpenCV Python

  16 avril 2014, par b_m

  I started working on a new computer a tried to set everything as it used to be on my old one. Unfortunately switching to 64bit Windows made everything quite difficult.

  With the current setup I can only open raw I420 videos converted with memcoder, but I can't open DivX/XVID videos, that I used to on my old PC. I tried ffdshow and K-Lite codec pack. Opening the videos in gspot shows that the codecs are indeed installed.

  I've searched for solution all over the Internet, but I couldn't find the solution. I've tried copying the ffmpeg dll into the Python27 folder.

  The environment is 64bits Windows 7 Pro

  EDIT :

  I tried saving a video using OpenCV :

  I passed -1 to the cv2.VideoWriter function to get the codec selection dialog. The dialog dosn't show the ffdshow codecs.

• cannot execute cmd.exe in server

  30 novembre 2012, par Lynx

  I use ffmpeg to grab a thumbnail from video file. To run the, the code need to call the cmd.exe from process.Start(). But when the code deployed in server, there is no thumbnail created and of course the thumbnail destination folder is set to read/write permission.
  So i assume it not authorized to access/execute the cmd.exe in server(shared server), after googled the problem.
  But i still cannot find a solution on this.
  Or maybe can i just copy the cmd.exe from my local machine and and include it web app so i can run it from the cmd.exe that i copied not from server cmd.exe. If this would work, how to do it ?

  string thumbargs = "-i \"" + videofile + "\" -s 60*25 -ss 00:00:00 -vframes 1 -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.RedirectStandardError = true;
  
  process.StartInfo.CreateNoWindow = true;
  
  process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
  
  
  
  try
  
  {
  
       process.Start();
  
       //string output2 = process.StandardError.ReadToEnd();
  
       //process.WaitForExit();
  
       if (process != null)
  
       {
  
            process.Close();
  
       }
  
  }
  
  
  
  catch(Exception ex)
  
  {
  
      this.lblMessage.Text = ex.Message.ToString();
  
  }

• Anomalie #3221 (Nouveau) : Sélecteur de rubrique Ajax

  2 juin 2014, par Eric Camus

  Bonjour,

  SPIP 3.0.16 de base sans aucun plugin.

  Contrairement à ce qui est écrit en commentaire avant la fonction "selecteur_rubrique_ajax" :
  " * la verification est faite a l’arrivee des donnees (Fil)", le déplacement d’un article par un administrateur restreint de sa rubrique vers une rubrique ou il n’a pas les droits est parfaitement fonctionnel, seul le déplacement d’une rubrique n’aboutit pas.

  Conclusion : un administrateur restreint peut écrire des articles publiés partout !!!

  On en parle aussi ici : http://core.spip.org/issues/2523

  Seule solution pour éviter ce "bug de sécurité" : mettre "define(’_SPIP_SELECT_RUBRIQUES’,100000) ; /* mettre 100000 pour desactiver ajax */" dans "mes_options.php".
