  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
    Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

  • Error in ffmpeg conversion

    9 avril 2015, par Adam Mo.

    I have a VPS 1G RAM with CentOS 6 i386 minimal installed and installed ffmpeg by ffmpeginstaller.com to setup clipbucket 2.7 in the VPS.
    when I test the ffmpeg by this command :

    wget "http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_720p_surround.avi"
    
ffmpeg -i big_buck_bunny_720p_surround.avi -vcodec libx264 big_buck_bunny_720p_surround-H264.avi

    by following this tutorial I get error

  • Raspberry crosscompilation in Eclipse

    27 juin 2018, par gogoer

    I want to compile an application for Raspberry in Eclipse (in windows). I installed SysGCC, configured Eclipse for crosscompiling. And if I create something like "Hello world" - everything is ok. Eclipse creates binaries which wonderfully works on Raspberry.
    But i need use FFMPEG libraries in my application . Here the minimal code of application :

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

    
int main(void) {
    
    av_register_all();
    
    return EXIT_SUCCESS;
    
}

    I added libraries in project config. Project compiles good, but linker gives a lot of errors :

    C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\usr\local\lib\libavcodec.a(aaccoder.o): In function `quantize_and_encode_band_cost_template':

collect2.exe: error: ld returned 1 exit status
    
make: *** [ffmpeg] Error 1
    

    
02:21:24 Build Finished (took 8s.394ms)

    SOLVED :

    i used next command :

    arm-linux-gnueabihf-gcc -L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\sysroot\usr\local\lib" -L"C:\SysGCC\Raspberry\arm-linux-gnueabihf\lib" -o "ffmpeg"  ./src/ffmpeg.o   -lc -lm -lpthread -lavformat -lavcodec -lswscale -lavutil -lavfilter -lavdevice -lswresample -lpostproc -ldl -lx264 -lgcc -lz

    where -lc -lm -lpthread -lavformat -lavcodec -lswscale -lavutil -lavfilter -lavdevice -lswresample -lpostproc -ldl -lx264 -lgcc -lz are libraries linker needs (maybe not all of them).
    please note that order is important.
