  • 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" (...)

  • 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
    the output :

  • 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.

  • qsv : add requirement for the mininal version of libmfx

    qsv : add requirement for the mininal version of libmfx

    libmfx 1.28 was released 3 years ago, it is easy to get a greater
    
version than 1.28. We may remove lots of compile-time checks if adding
    
the requirement for the minimal version in the configure script.
