• How can I reset the path of FFMPEG in the VideoExport library in Processing ?

  11 avril 2021, par bella

  Note : This question was originally titled "How can I reset the path of FFMPEG in Java ?" but, as it has been pointed out in the comments and the answer, the issue is not with Java, so I've changed the title to make it easier to find for others with the same issue.

  I accidentally set the path for FFMPEG to a different folder, and I can't change it back.

  


  I'm using Processing (the library and its IDE) and the user-created Video Export library to capture and write to an mp4 video file. The library required FFMPEG, so I downloaded and installed it. After I installed it, I ran the code, and the library called Java to request the path of FFMPEG. I wrongly set the path to a different folder (which I eventually deleted), and immediately realized my mistake. I ran the code again to see if I could trigger the prompt again to correct the path.

  The console response I received was : (I'm sure most of it doesn't have to do with the actual issue. However, I wanted to show all of it in case it somehow does.)

  I need to find a way to reset the path of FFMPEG that Java has. I have tried uninstalling and reinstalling the library, but I haven't tried Java (I don't want to mess with anything it has in its current state).

  


• Anomalie #4014 (Nouveau) : Différence entre critères {id_xx} et {id_xx ?} avec id_xx un tableau

  14 octobre 2017

  Soit un squelette de test appelé avec ?page=test&id_mot[]=1&id_mot[]=2&id_mot[]=3&id_mot[]=4&id_mot[]=5&id_mot[]=6
  et 2 boucles avec pour seule différence le ?
  

  #ID_MOT
  #ID_MOT
  

  Dans le premier cas la requête SQL crée un IN avec les différents identifiants.
  Dans le second cas la requête SQL générée est en erreur avec un where : (mots.id_mot = (2 1 (3) : 4))
  (notons que ça s’arrête au 4è élément du tableau)

  Quel comportement devrait-il y avoir ?
