  • 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 (...)

  • Compiling ffmpeg for use in Android (ndk) for x86 architecture

    26 septembre 2012, par Ankur22

    I am trying to compile ffmpeg for Android but for the x86 architecture. I've successfully compiled an arm .so and it all works, and I though that by replacing arm with x86 in the relevant places within the build script would have done the trick. Unfortunately that's not the case and I get some strange things occurring.

    First I get this while it's compiling ffmpeg :

    /home/ankur/android-ndk-r8/platforms/android-8/arch-arm//usr/include/strings.h:49: warning: redundant redeclaration of 'index'

    Notice the arch-arm instead of arch-x86. Finally I get this :

    /home/ankur/android-ndk-r8/toolchains/x86-4.4.3/prebuilt/linux-x86/bin/i686-android-linux-ld: libavcodec/libavcodec.a(4xm.o): Relocations in generic ELF (EM: 40)

  • Compile FFMPEG for command line usage

    3 septembre 2014, par Lior Iluz

    I’ve been trying to compile FFMPEG so I can use it with my Android application with commands. The result should be 1 static file, "ffmpeg", that is not package dependent. No .so files.

    I managed to compile it with guardianProject and everything is working but the source was too old and lacks options I need.
    I’m using the latest Ubuntu on VirtualBox, all essentials are installed and updated (gawk, yasm, aptitude, etc...).

    There are multiple examples around the web. Here are the issues I’ve experienced with each of the options I tried. I’d appreciate help with either one of the following errors :

    1. Guardian project - I managed to compile it and get the ffmpeg file but it uses an old version of ffmpeg that doesn’t include the "-movFlags faststart" option. I tried throwing the new ffmpeg (2.3.3) in there but it just throws error. (I ran git submodule init and update)

    2. JayH5 - A more generic build file that basically should work with every ffmpeg. I updated the build script to work with the latest NDK and it seems to be working but than it fails on /home/dor/Desktop/ndk/android-ndk-r10/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/arm-linux-androideabi-pkg-config not found, library detection may fail.
      I read about this and it seems to require a hack, which I don’t understand how to implement.

    3. Trovao - this is a very nice project and the build script even downloads the latest ffmpeg and x264 sources, and I even succeeded in compiling it to FFMPEG and X264 files but when I use it, I get this error : could not load library "libx264.so.142 which is weird, as x264 is there and the whole idea of this project is to cancel the need of .so files.

    I’d appreciate help with figuring out how to solve any of the issues. I prefer using the JayH5 build script as it seems the most straight forward out there...

    JayH5 build file :

    #!/bin/bash
