  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).

  • SWF to PNG.. but merge all pngs inside into 1

    14 novembre 2014, par Jayden

    The title says it all,

    I’ve tried swftools and ffmepg but I don’t ’think’ they achieve what I need to do.

    Basically there is a SWF file that is made up of up to 60 images, them 60 images inside the SWF all are parts of an image that make up 1 final image or animation on an online game.

    I need to be able to download the swf as a png image with the same output it will look like on the virtual game - so not 60 images if seperate graphics, just one image with them all (merged ?) together.

    I am not even sure if this is possible to do in the commandline so if you understand any of this, please point me in the right direction.

    I am using Ubuntu 14.04

  • Compile FFMPEG + x264 - undefined references

    18 juin 2013, par Tishu

    I have been trying to find a solution online for a couple of days with no luck. I am using Ubuntu and trying to compile the latest FFMPEG stable version (1.0.1) with x264 support. I made sure I uninstalled any existing x264 then I downloaded the latest x264 source and compiled it with the following config :

    ./configure --prefix=$PREFIX \
    
    --enable-shared \
    
    --enable-static \
    
    --disable-gpac \
    
    --extra-cflags=" -I$ARM_INC -fPIC -DANDROID -fpic -mthumb-interwork -ffunction-sections -funwind-tables -fno-short-enums -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -Wno-psabi -march=armv5te -msoft-float -mthumb -Os -fomit-frame-pointer -fno-strict-aliasing -finline-limit=64 -DANDROID -Wa,--noexecstack -MMD -MP " \
    
    --extra-ldflags=" -nostdlib -Bdynamic -Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,nocopyreloc -Wl,-soname,/usr/lib/libz.so -Wl,-rpath-link=$ARM_LIB,-dynamic-linker=/system/bin/linker -L$ARM_LIB -lc -lm -ldl -lgcc" \
    
    --cross-prefix=${ARM_PRE}- \
    
    --disable-asm \
    
    --host=arm-linux \
    

    
    make clean
    
    make install

    All goes well, and I checked the installed version :

    x264 -V
    
    x264 0.129.x
    
    built on Dec 27 2012, gcc: 4.6.1
    
    configuration: --bit-depth=8 --chroma-format=all
    
    x264 license: GPL version 2 or later

    I then try to compile FFMPEG with the following options :

    ./configure --target-os=linux \
    
    --enable-libx264 \
    
    --enable-gpl \
    
    --prefix=$PREFIX \
    
    --extra-cflags="-I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/ffmpeg-1.0.1/android/armv7-a/include -I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/x264 -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -Dipv6mr_interface=ipv6mr_ifindex -fasm -Wno-psabi -fno-short-enums  -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " \
    
    --extra-ldflags="-Wl,-rpath-link=$PLATFORM/usr/lib -L/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/ffmpeg-1.0.1/android/armv7-a/lib -L$PLATFORM/usr/lib -nostdlib -lc -lm -ldl -llog" \
    
    --enable-cross-compile \
    
    --extra-libs="-lgcc" \
    
    --arch=arm \
    
    --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
    
    --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
    
    --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
    
    --sysroot=$PLATFORM \

    The configure and make clean/make install work well, but when I try to create the .so file the following command fails :

    /home/tishu/Apps/android-ndk-r8d/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ld

    This fails with the following output :

    The x264 version it is looking for (129) is the one installed and compiled succesfully with —eanable-shared. Obviously all compiles fine when I do not include libx64.

    Question : How can I specify the include path for the last command ? I tried adding the path to $PATH and also adding this as an argument with no luck : -I/home/tishu/Workspaces/ffmpeg/ffmpeg/jni/x264

    Thanks
