  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • MediaSPIP v0.2

    21 juin 2013, par

    MediaSPIP 0.2 est la première version de MediaSPIP stable.
    Sa date de sortie officielle est le 21 juin 2013 et est annoncée ici.
    Le fichier zip ici présent contient uniquement les sources de MediaSPIP en version standalone.
    Comme pour la version précédente, il est nécessaire d’installer manuellement l’ensemble des dépendances logicielles sur le serveur.
    Si vous souhaitez utiliser cette archive pour une installation en mode ferme, il vous faudra également procéder à d’autres modifications (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • make error in OpenCV installation on ubuntu (ffmpeg CODEC_ID_XXXX was not declared in scope)

    22 avril 2015, par Anurag Priyadarshi

    I am trying to install OpenCV following this tutorial. I am through cmake.(The configuration is given at the end.) However make shows error :make[2]: ***[modules/highgui/CMakeFiles/opencv_highgui.dir/src/cap_ffmpeg.cpp.o] Error 1
    One link pointed out reason as different version of opencv and ffmpeg, but I found a piece of code in cap_ffmpeg_impl.hpp that appears to be handling it.

    #if LIBAVCODEC_BUILD >= CALC_FFMPEG_VERSION(54,25,0)
    #  define CV_CODEC_ID AVCodecID
    #  define CV_CODEC(name) AV_##name
    #else
    #  define CV_CODEC_ID CodecID
    #  define CV_CODEC(name) name
    #endif

    Not sure if it is ok for this to be commented.

    Also, I could try installing ffmpeg seperately, but I am not sure how dependencies are handled in this installation around libav.

    Would be thankful for any help in solving this problem, as well as tips/links for OpenCV installation in general.

  • Installing full multimedia stack on server (ffmpeg,mp4box,sox,mplayer)

    29 avril 2015, par hdezela

    I’ve had a trusty text file with all(?) the steps I need to set up a full multimedia stack on a RHEL compatible server (CentOS, AWS Linux, etc.) for a few years now. However, sometimes some things are missing and I need to revise it. I know it is not complete so I’m asking for suggestions/modifications in order to get a good - and public - list of how to install all this stuff easily.

    Ideally, I want to be able to run through the file and end up with a system that’ll take any media file and be able to convert/encode/decode/whatever with it.

    This is what I have :

    yum install mesa-libGL-devel mesa-libGLU-devel libXi-devel libXmu-devel freeglut-devel freeglut ncurses-devel
    cd /usr/local/src
    mkdir /usr/local/src/tmp
    chmod 777 /usr/local/src/tmp

  • Undefined symbols _init_xrpow_core_init in libmp3lame.a

    10 septembre 2015, par mbelsky

    I’m using ffmpeg tool with x264 in my android project for encoding video. Now I wanna add audio convert feature, from 3gpp to mp3. As I understand I should add libmp3lame to ffmpeg bin.

    I’ve downloaded last lame version and updated few files :

    android_build.sh

    #!/bin/bash

    . settings.sh

    BASEDIR=$(pwd)
    TOOLCHAIN_PREFIX=${BASEDIR}/toolchain-android

    for i in "${SUPPORTED_ARCHITECTURES[@]}"
    do
     rm -rf ${TOOLCHAIN_PREFIX}
     ./x264_build.sh $i $BASEDIR 0 || exit 1
     ./lame_build.sh $i $BASEDIR 0 || exit 1
     ./ffmpeg_build.sh $i $BASEDIR 0 || exit 1
    done

    rm -rf ${TOOLCHAIN_PREFIX}

    lame_build.sh

    #!/bin/bash

    . abi_settings.sh $1 $2 $3

    pushd lame

    make clean

    case $1 in
     armeabi-v7a | armeabi-v7a-neon)
       HOST=arm-linux
     ;;
     x86)
       HOST=i686-linux
     ;;
    esac

    echo $CFLAGS

    ./configure \
     --with-pic \
     --host="$HOST" \
     --enable-static \
     --disable-shared \
     --prefix="${TOOLCHAIN_PREFIX}" || exit 1

    make -j${NUMBER_OF_CORES} install || exit 1

    popd

    ffmpeg_build.sh

    #!/bin/bash
    . abi_settings.sh $1 $2 $3

    pushd ffmpeg

    case $1 in
     armeabi-v7a | armeabi-v7a-neon)
       CPU='cortex-a8'
     ;;
     x86)
       CPU='i686'
     ;;
    esac

    make clean

    ./configure \
    --target-os="$TARGET_OS" \
    --cross-prefix="$CROSS_PREFIX" \
    --arch="$NDK_ABI" \
    --cpu="$CPU" \
    --enable-runtime-cpudetect \
    --sysroot="$NDK_SYSROOT" \
    --enable-pic \
    --enable-libx264 \
    --enable-libmp3lame \

    --disable-ffplay \
    --disable-ffprobe \
    --enable-gpl \
    --enable-yasm \
    --disable-doc \
    --disable-shared \
    --enable-static \
    --pkg-config="${2}/ffmpeg-pkg-config" \
    --prefix="${2}/build/${1}" \
    --extra-cflags="-I${TOOLCHAIN_PREFIX} -I${MP3LAME}/include $CFLAGS" \
    --extra-ldflags="-L${TOOLCHAIN_PREFIX} -L${MP3LAME}/lib $LDFLAGS" \
    --extra-libs="-lm" \
    --extra-cxxflags="$CXX_FLAGS" || exit 1

    make -j${NUMBER_OF_CORES} && make install || exit 1

    popd

    Result of ./android_build.sh :
