Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.
Version mono serveur
La version mono serveur consiste à n’utiliser qu’une (...) -
Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -
Soumettre améliorations et plugins supplémentaires
10 avril 2011Si vous avez développé une nouvelle extension permettant d’ajouter une ou plusieurs fonctionnalités utiles à MediaSPIP, faites le nous savoir et son intégration dans la distribution officielle sera envisagée.
Vous pouvez utiliser la liste de discussion de développement afin de le faire savoir ou demander de l’aide quant à la réalisation de ce plugin. MediaSPIP étant basé sur SPIP, il est également possible d’utiliser le liste de discussion SPIP-zone de SPIP pour (...)

best approach for extract / extracting images / image sequence from videos / video file in Java
20 février 2017, par Daniel RufWell, there is FFMPEG and some Java bindings and wrappers for it but I need to distribute for each specific platform the right binary file of FFMPEG.
Isnt there any plain Java solution or library without any dependencies like FFMPEG for converting a video fle to an image sequence ?
Solutions like FFMPEG, XUGGLER or JMF (abandoned) are not suitable. Is there really no pure Java solution for this ?
Maybe for specific video codecs / files at least ?
I just want to extract the images from the video file to jpeg / png files and save them to the disk

Static Compilation of FFmpeg with x264 support
17 février 2014, par b1izzardBased on the Tutorial, I tried to build the latest FFmpeg binary with x264 support for Command line execution using Android-ndk-r9c.
I had built the x264 using the below script :

building ZVBI for arm7
14 janvier 2014, par DineshI am trying to build zvbi lib for ios arm7 architecture. If any body has done this earlier can give me some pointers. I have managed to build the same for simulator using
./configure prefix="" CC="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/us r/bin/gcc" CFLAGS="-arch i386" LDFLAGS="-arch i386 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk"But i am not sure how to build the same with arm Architecture.
