    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Menus personnalisés

  • ffmpeg with frei0r libraries fails on os x 10.14.6

    13 novembre 2019, par Bernhard Wagner

    I’m on Mac OS X 10.14.6 (Mojave), used homebrew to install both ffmpeg and frei0r.
    If you check the output below, the option --enable-frei0r is there.

    I verified the path to the frei0r libaries and call ffmpeg like this :

    FREI0R_PATH=/usr/local/Cellar/frei0r/1.6.1/lib/frei0r-1/ ffmpeg -v debug -i running.mkv -filter:v frei0r=pixeliz0r=0.02:0.02 pixel.mkv

    however it fails the exact same way as if I hadn’t passed the env var FREI0R_PATH :

    FREI0R_PATH=/usr/local/Cellar/frei0r/1.6.1/lib/frei0r-1/ ffmpeg -y -v debug -i running.mkv -filter:v frei0r=pixeliz0r=0.02:0.02 pixel.mkv
