  • 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 (...)

  • 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.

  • Ffmpeg - Convert Wav to OGG on Android (wrong metadata on some devices)

    13 décembre 2016, par Pepa Zapletal

    I have in the app Wav file and I want to convert it to the OGG format.

    I’m using ffmpeg library for it and this command :

    ffmpeg -i /storage/emulated/0/Test.wav -c:a libvorbis -q:a 5 /storage/emulated/0/Test.ogg

    But I have problem play correctly the generated OGG file on some Android devices. If I open this file in standard MediaPlayer then I get the wrong file duration, seeking is also not working very well BUT the file is played whole and correctly. This happens for example on Huawei M2 with Android 5.1 but on Samsung Galaxy S5 (with Android 5.1) the generated file is OK and playing is also OK.

    Do you have some idea where can be a problem ?

  • Error FFmpeg in Android

    19 novembre 2013, par Mark

    I'm using FrameGrabber to load a video from sdcard and perform some image processing operation. I followed the tutorial at JavaCV site to load javacc and ffmpeg.
    Currently, to run the application, I'm using my tablet (Asus TF 101G with Android version 4.0.3) connected to my pc and it works fine. But if I try to run the same application in another device (e.g. Nexus with Android 4.1.2) I get these errors :

    Any suggestion please ?

    I want to attach also my Android.mk file

include $(BUILD_SHARED_LIBRARY)

    and my Apllication.mk file

APP_ABI := armeabi armeabi-v7a 
    
#APP_ABI := all

    Any suggestion ?
    Thanks

    Also I tried to change the application.mk file in this way but with no results :

    APP_STL := gnustl_static
    
APP_CPPFLAGS := -frtti -fexceptions
    
APP_ABI := armeabi
    
LOCAL_CFLAGS += -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -mfpu=neon
    
LOCAL_LDLIBS += -Wl,--fix-cortex-a8
    
APP_PLATFORM := android-8

  • Errors while Cross compiling of ffmpeg for MIPS Openwrit

    6 octobre 2015, par goldenmean

    I am in process of cross-compiling ffmpeg for MIPS openwrt. I have built this cross-compilation toolchain myself from openwrt build-root.

    Now I am using that toolchain to cross compile ffmpeg. But the final step of build, linking is failing. Details below.

    The steps taken so far -

    1. ./configure of ffmpeg is done with correct cross-compilation options is successful

    2. There were some errors but after manually editing config.h , those were fixed.

    3. The compilation of libraries (libavformat, libavcodec,...) is successful

    4. Linking fails with error
      mips-openwrt-linux-uclibc-ld : cmdutils.o : undefined reference to symbol ’putchar’

    mips-openwrt-linux-uclibc-ld : note : ’putchar’ is defined in DSO /libc.so.0 so try adding it to the linker command line

    libc.so.0 : could not read symbols : Invalid operation

    make : *** [ffmpeg_g] Error 1

    I see that libc.so.0 is a sym link to libuClibc-0.9.33.2.so
    So then when I added this directory which has to LD_LIBRARY_PATH it gave all kinds of endianness mismatch errors like :

    pr : error while loading shared libraries : libpthread.so.0 : ELF file data encoding not little-endian

    Below is my ffmpeg configure command while cross-compiling ffmpeg -
