  • 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':

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.

  • 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
