  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Trying to use FFMPEG for android. Compiling but still not working

    15 avril 2014, par Austin Mueller

    So to start off... Im trying to use ffmpeg to compile an array of images into a video on Android.

    I have followed a variety of tutorials online and have gotten as far as being able to compile the lib for Android and still have to project run.
    The repo im now using can be found here : https://github.com/Batterii/android-ffmpeg-x264

    I made a couple tweaks to the setttings.sh just to correct ndk location. Besides that, I followed the instructions and it seemed to work flawlessly.

    After that, I converted the "Project" project into an Android stdio library module.
    Screenshot of android studio module

    I am not getting any compile errors, nor am I getting any runtime errors, or any other errors that I can detect... Nothing on logcat... But I am definitely not getting any video called out.mp4.
    In an onCreate of a particular activity, I am running this code :

    Videokit vk = new Videokit();
    
vk.run(new String[]{"ffmpeg", "-r", "1/5", "-i", "%d.jpg", "-c:v", "libx264", "-r", "30", "-pix_fmt", "yuv420p", project.getProjectDirectory() + "/out.mp4"});

    This command is taken from the command line example found here :
    https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images

    Thank you in advance for anyone taking the time to look through this post... I am pretty baffled at this point, as there are no errors I can find and no video...
    Thanks

    ======================================================================

    Update

    Turns out it is not actually compiling correctly... but i have found a few things.
    here is the make file from the Eclipse version of the project

    LOCAL_PATH := $(call my-dir)
    

    
include $(CLEAR_VARS)
    
LOCAL_MODULE  := videokit

    I've been messing around with it for a couple hours now and pretty much every time, i get gradle yelling at me about the fact that it can't find some file. I'm beginning to think that maybe it is because my LOCAL_LDLIBS aren't in the same order as the original...? Im not entirely sure... Does anyone else have any ideas...?

    Remise a plat des listes d’objet :
    structure commune .liste[.long][.short] &gt ; .liste-items[.long][.short] &gt ; .item
    le contenu de chaque .item est fourni par inclure/resume/xxx.html (article, rubrique, breve... a completer) qui a une structure commune (héritée de hNews) dans un &lt ;article&gt ;
    Les classes modificatrices .long ou .short permettent d’avoir une liste plus detaillee ou plus courte, mais ce n’est qu’une option de presentation, le html etant identique.
    Le seul parametre pris en compte par resume/xxx est "coupe" qui permet de changer la longueur de coupe
    Un repertoire de demo (activé pour les seuls webmestres) avec une page de presentation des listes (toutes variantes)
    .secondary sur le contenu secondaire du layout (les colonnes)
