• ffmpeg : Resource temporarily unavailable

  26 octobre 2015, par Cabbage soup

  I’m trying to run ffmpeg on a linux server (info from uname -a) :

  Linux comp32 2.6.32-279.14.1.el6.x86_64 #1 SMP Tue Nov 6 11:21:14 CST 2012 x86_64 x86_64 x86_64 GNU/Linux

  ffmpeg (together with the required encoders and decoders) compiles successfully on the system, but when I try to perform a basic operation like the following : ffmpeg -v debug -i example.m4v image%d.jpg, I get a slightly cryptic error message :

  I also tried using a static build off ffmpeg, downloaded from here, but got the same resource temporarily unavailable message. Any ideas on how I might be able to fix this ?

• Anomalie #3571 : nettoyage du dossier tmp/cache/wheels

  26 octobre 2015, par - Equipement

  Bonjour,

  J’ai constaté que le dossier tmp/cache/wheels d’un site (sans le plugin memoization) contient :
  - 5 fichiers tw-....txt
  - des dizaines de fichiers datasource-....txt

  J’ai ajouté une trace dans les logs dans la fonction cache_set de plugins-dist/*textwheel*/inc/memoization-mini.php

  function cache_set($key, $value) 
      $dir = sous_repertoire(_DIR_CACHE,"wheels/") ;
  spip_log("CI CACHE SET de textwheels :".$dir.$key.".txt",_LOG_ERREUR) ;
      return ecrire_fichier($dir.$key.".txt", serialize($value)) ;
  
  

  J’ai également ajouté une trace dans les logs dans la fonction cache_set de ecrire/*iterateur*/data.php :

      protected function cache_set($cle, $ttl, $valeur = null) 
          if (!$cle) return ;
          if (is_null($valeur)) 
              $valeur = $this->tableau ;
          
          # utiliser memoization si dispo
          include_spip(’inc/memoization’) ;
  spip_log("CI CACHE SET de iterateur : A",_LOG_ERREUR) ;
          if (!function_exists(’cache_set’)) return ;
  spip_log("CI CACHE SET de iterateur : B",_LOG_ERREUR) ;
          return cache_set($cle,
              array(
                  ’data’ => $valeur,
                  ’time’ => time(),
                  ’ttl’ => $ttl
              ),
              3600 + $ttl) ;
      
  

  Ensuite, dans l’espace privé du site, j’ai consulté les statistiques d’un article. Les logs montrent que 2 fichiers datasource....txt ont été créés dans /tmp/cache/wheels. Un examen du répertoire le confirme.

  2015-10-26 15:04:25 ... :Pri:ERREUR : CI CACHE SET de iterateur : A
  2015-10-26 15:04:25 ... :Pri:ERREUR : CI CACHE SET de iterateur : B
  2015-10-26 15:04:25 ... :Pri:ERREUR : CI CACHE SET de textwheels : ../tmp/cache/wheels/datasource_acc0b40712268d73bce5056d75e2d22b.txt
  2015-10-26 15:04:25 ... :Pri:ERREUR : CI CACHE SET de iterateur : A
  2015-10-26 15:04:25 ... :Pri:ERREUR : CI CACHE SET de iterateur : B
  2015-10-26 15:04:25 ... :Pri:ERREUR : CI CACHE SET de textwheels : ../tmp/cache/wheels/datasource_5d2bd35e83ad81cf50437400f60004db.txt
  

  Dans la fonction cache_set de ecrire/*iterateur*/data.php, le traitement continue après le test d’existence de la fonction ’cache_set’. Or le site n’a pas le plugin memoization, et un examen des sources montre que cette fonction (pas la méthode) existe uniquement dans plugins-dist/*textwheel*/inc/memoization-mini.php. C’est donc cette dernière fonction qui est utilisée par erreur par l’itérateur.

  Bueno como mis presentimientos eran ciertos. El problema es de la versión del spip 3.0.20. Me atrase a la versión 3.0.17 y anda bien el el GD2.
  

  
  GD filters don’t work :
