bonjour,

j'ai installe piwigo 2.5.3, et ai quelques video encodées en mp4.
j'utilise le plugin videojs.
en version 5.2.2, sauf erreur de ma part, mes videos fonctionnaient correctement.

en 5.2.3, quand j'essaie de synchroniser mon repertoire de video ( sync sur l'onglet du plugin), j'ai cette erreur :

que lui-je faire svp ?
j'ai tente quelques options dans le menu maintenance, sans succès.
je décoche la case Simulation, quand je synchronise.

merci
Olivier
