    Le site central/maître de la ferme a besoin d’utiliser plusieurs plugins supplémentaires vis à vis des canaux pour son bon fonctionnement. le plugin Gestion de la mutualisation ; le plugin inscription3 pour gérer les inscriptions et les demandes de création d’instance de mutualisation dès l’inscription des utilisateurs ; le plugin verifier qui fournit une API de vérification des champs (utilisé par inscription3) ; le plugin champs extras v2 nécessité par inscription3 (...)

  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • Native function in Vitamio

    1er août 2014, par hclee

    I am now looking the code beind the Vitamio (media framework) cause I want to know what API does it use to retrieve the buffer percentage/download rate and how it interect with the android OS to retrieve other information about the streaming video.

    But I realized that it does use some native functions which enable it use some code written in C/C++ language.

    I try to investigate on the C++ code but I don’t know where are they.
    I guessed they are stored inside the res/raw/librarm.so.
    I unzipped the file but all I can find is some machine code but what I want is the implementation of the native function.

    For example, I want to know the implementation of the following function :

    public native int getVideoTrack() ; // What is this function for ? What does it mean by the track
    // number of a straming video ?

    or

    private static native boolean loadFFmpeg_native(String ffmpegPath) ;

    and when will this function be called :

    private static void postEventFromNative(Object mediaplayer_ref, int what, int arg1, int arg2, Object obj)

    Do anyone know where can I investigate the implementation of such native function.
    It should be some C++ code but I don’t want machine code...

    I went to
    https://www.vitamio.org/en/2013/Tutorial_0509/13.html

    but they didn’t have the thing that I want

    Thanks in advance !!!

  • FFplay show time when cursor is active

    7 janvier 2018, par Slump 64

    So recently I’ve found solution to make my ffplay display time at the bottom of the video playing

    ffplay -vf "drawtext=text='%{pts\:hms}':box=1:x=(w-tw)/2:y=h-(2*lh)"

    Can I make it show time only if I use cursor and then show nothing when cursor is fading or when I press SPACE ?

    Edit : OR show how much time out of total is played, or even a percentage.

  • AFTER PHP-FFMpeg not converting (error with ffmpeg)

    15 juin 2018, par Magurean Dan Sergiu

    I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

Unknown encoder 'libx264'

    My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

    After a few modifications

    I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.
