  • Gestion des droits de création et d’édition des objets

    8 février 2011, par

    Par défaut, beaucoup de fonctionnalités sont limitées aux administrateurs mais restent configurables indépendamment pour modifier leur statut minimal d’utilisation notamment : la rédaction de contenus sur le site modifiables dans la gestion des templates de formulaires ; l’ajout de notes aux articles ; l’ajout de légendes et d’annotations sur les images ;

  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.
    Modification lors de l’ajout d’un média
    Lors de l’ajout d’un média de type "image" un nouveau bouton apparait au dessus de la prévisualisation (...)

  • Le plugin : Gestion de la mutualisation

    2 mars 2010, par

    Le plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
    Installation basique
    On installe les fichiers de SPIP sur le serveur.
    On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
    On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

  • Java execute command doesn't work in code

    27 août 2017, par Ariana

    I am calling java.lang.Runtime.exec(...) in my Java program to run a command (some FFMPEG commands) simply passed to my function :

        private static void RunCommand(String command) throws InterruptedException {
    
        try {
    
            // Execute command
    
            Process proc = Runtime.getRuntime().exec(command);
    
}
    
}

    It runs OK for simple FFMPEG cases such as ffmpeg -i input.avi -c copy output.avi.

    But for one of the commands, apparently it doesn’t run. When I copy/paste the exact String in command line, I am able to run it and see the output file.

    ffmpeg -i "concat:/home/temp10.avi|/home/p2.avi|/home/temp15.avi" -c copy -y /home/output.avi

    Which is the following in code :

    String c4="ffmpeg -i \"concat:"+dir+temp1+"|"+dir+ad+"|"+dir+temp3+"\" -c copy -y "+dir+output;

    What is going on ? Any guesses why it doesn’t run in code ? If the " is causing the problem, why the corresponding string looks good ?!

  • "no archive symbol table (run ranlib)" issue with static linking FFmpeg for android

    9 octobre 2017, par Programist

build_ffmpeg_android

    The output of above script is placed inside ffmpeg-3.3.4/android/arm.

    Problem :
    When trying to link to these .a libraries from my app using -lavformat -lavcodec -lswscale -lavutil -lavfilter -lswresample -lavdevice,
    I get the following linker error for each of them

    :-1: error: error: avformat: no archive symbol table (run ranlib)
    
:-1: error: error: avcodec: no archive symbol table (run ranlib)
    
:-1: error: error: swscale: no archive symbol table (run ranlib)
    
:-1: error: error: avutil: no archive symbol table (run ranlib)
    
:-1: error: error: avfilter: no archive symbol table (run ranlib)
    
:-1: error: error: swresample: no archive symbol table (run ranlib)
    
:-1: error: error: avdevice: no archive symbol table (run ranlib)

    Looking at this discussion here, I am doing it correct by selecting arm-linux-androideabi-ar in CPREFIX.

    Trying to solve the error, I’ve also added the following configure flag for ranlib to be picked up specifically for android but doesn’t seem to help.

    RANLIB=$TOOLCHAIN/bin/arm-linux-androideabi-ranlib

    Question :
    What else am I missing here ?
    What is needed in my buildscript.sh to pick the correct ranlib & stop complaining about archive symbol table when linking from my app ?

  • Error : failed to run custom build command for `ffmpeg-sys-next v6.0.1`

    5 décembre 2023, par mox

    I am trying to make a program that converts a MP4 into a gif and vice versa by decoding its packets and encoding them into a MP4 (or gif), I am using ffmpeg-next package (which uses ffmpeg rust behind it) to do this, my operating system is Linux 22.04 Ubuntu LTS (ARM64). When i try to build the program using cargo build i am met with a very long error message.

    &#xA;

    I am aware of the problem, it cannot find the libavdevice in the PKG_CONFIG.

    &#xA;

    I have tried installing the libavdevice package using sudo apt install libavdevice but Ubuntu cannot find it, i also tried installing the ffmpeg package directly, i had also searched the same error message, someone else had the same error issue but after running the solution provided by someone it still does not build/work.
