Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

Samsung S3 : 'Cannot play Video' on stock Video player
18 mars 2013, par d33pikaI am unable to play a mp4 video(H.264 Baseline, AAC) on Samsung S3, Android Version : 4.1.1, stock video player but plays on VLC. The same video plays on Galaxy Beam, Android Version : 2.3.6, stock Video Player. I want to figure out why it does not play on S3. I ran ffprobe and mediainfo on the fie :
