  • 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.

  • ffmpeg cross compiles nicely for aarch64, but when linking with my project, gives Relocations in generic ELF (EM : 62)

    29 août 2019, par Lucas Zanella

    Here’s how I’m configuring ffmpeg :

            ./configure \
    
        --prefix=${BUILD_DIR}/desktop/aarch64 \
    
        --disable-doc \
    
        --enable-cross-compile \
    
        --cross-prefix=aarch64-linux-gnu-\
    
        --target-os=linux \
    
        --arch=aarch64 \
    
        --extra-cflags="-O3 -fPIC" \
    
        --enable-shared \
    
        --disable-static \
    
        --disable-debug \
    
        --disable-runtime-cpudetect \
    
        --disable-programs \
    
        --disable-muxers \
    
        --disable-encoders \
    
        --disable-decoders \
    
        ${DECODERS_TO_ENABLE} \
    
        --disable-bsfs \
    
        --disable-pthreads \
    
        --disable-avdevice \
    
        --disable-network \
    
        --disable-postproc 
    

    
        make clean
    
        make -j$(nproc)
    
        make install

    It compiles fine. Then, when I try to link my project with this compiled ffmpeg, it gives me

    In this answer : https://stackoverflow.com/a/23185739/10116440 he says that CC is missing. I’m also not using CC but shouldn’t CC be the same as --cross-prefix ?

    I also found http://lakm.us/logit/2012/11/cross-compiling-ubuntu-arm-ffmpeg/ in where he says that I should use --cross-prefix=arm-linux-gnueabi-, in my case arm should be aarch64. However, there’s no aarch64-linux-gnueabi- toolchain, only aarch64-linux-gnu-. Can it be the problem ? I think no because eabi looks like its for 32 bits, I guess

    It’s worth noticing that I’m bulding ffmpeg on a amd64 but using the static library to build my project on a aarch64.

  • lavu/tx : add support for double precision FFT and MDCT

    lavu/tx : add support for double precision FFT and MDCT

    Simply moves and templates the actual transforms to support an
    
additional data type.
    
Unlike the float version, which is equal or better than libfftw3f,
    
double precision output is bit identical with libfftw3.

  • Android NDK Cross Compile FFmpeg, dlopen failed : cannot locate symbol

    23 août 2019, par binglingziyu

    Android NDK-r20 cross compile FFmpeg4.2 success, but my app crash with

    UnsatisfiedLinkError : dlopen failed : cannot locate symbol
    __aeabi_idiv

    This is the ffmpeg4.2 source code with my "build_android.sh"

    ffmpeg-android-build

    config the NDK r20 root path in "build_android.sh"
    
$ cd ffmpeg-android-build
    
$ ./build_android.sh
    
$ make -j 4
    
$ make install

    This is my android project to test the ffmpeg

    ffmpeg-android-test

    Seemed the solution，don’t know how to do in my situation

    #cannot-locate-symbols

    Excepted

    1. NDK-r20 and FFmpeg-4.2 is needed (cant change the version)
    2. My android test project run
