  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • How we use FFMPEG Library in android for play more then one audio file ?

  • How to add a customized library (built from C++ OpenCV) to Ffmpeg ? [duplicate]

    3 septembre 2016, par Codecodeup

    This question already has an answer here :

    I have written and built a library as a standalone one with C API and C++ core code (based on OpenCV). I want to add it to FFmpeg as an external library. I have added it to the DEPENDENCIES list of FFmpeg, together with other external libraries, like openjpeg. I have also added "’—extra-libs=-lstdc++ -lmylibrary’ together with other args for compilation, like ’—enable-libopenjpeg’.

    However, I got the following error when compiling FFmpeg :
    .../binutils/2.25/centos6-native/da39a3e/bin/ld : .../mylibrary/0.1/gcc-4.9-glibc-2.20/80414d5/lib/libmylibrary.a(mylibrary_file.cpp.o) : undefined reference to symbol ’_ZdlPv@@GLIBCXX_3.4’
    .../libgcc/4.9.x/gcc-4.9-glibc-2.20/024dbc3/lib/libstdc++.so : error adding symbols : DSO missing from command line

    If I use ’—extra-libs=-lmylibrary -L/usr/lib64 -lstdc++’, I got :
    .../binutils/2.25/centos6-native/da39a3e/bin/ld : .../mylibrary/0.1/gcc-4.9-glibc-2.20-fb/80414d5/lib/libmylibrary.a(mylibrary_file.cpp.o) : relocation R_X86_64_32 against `.bss’ can not be used when making a shared object ; recompile with -fPIC
    .../mylibrary/0.1/gcc-4.9-glibc-2.20/80414d5/lib/libmylibrary.a : error adding symbols : Bad value

    Here, I tried gcc-4.9-glibc-2.20 and other versions but got the same results.

    I wonder if I missed anything.

    By the way, this question is not about mixing C and C++ (like this post : Using C++ library in C code). It is mainly about how to add an external library to FFmpeg.

    Thanks a lot for your help !

  • Compile error when using FFMPEG library

    9 novembre 2014, par Fjotten

    I have tried to compile a C program using FFMPEG but every time I compile it fails at the include statement :

    #include <libavcodec></libavcodec>avcodec.h>
    
#include <libavformat></libavformat>avformat.h>

    Gcc provides this error message :

    libavcodec/avcodec.h: No such file or directory

    I have installed FFMPEG and created the shared libraries, but when I try to link those libraries when I compile I get the same error.

    gcc main.c -L ffmpeg_build/lib -l ffmpeg_build/include/libavcodec/avcodec.h

    Do I get this error because I am linking the library incorrectly, or is there some other issue ?

    This is the first time I am using someone else’s library, so please excuse me if I am asking a silly question.
