  • Amélioration de la version de base

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • libFLAC/md5.c : Massive refactoring of format_input_ function.

    29 juin 2014, par Erik de Castro Lopo
    libFLAC/md5.c : Massive refactoring of format_input_ function.

    This refactoring is in preparation for fixing the cast-align warning when
    
compiling on ARM (and possibly others). Testing on stereo 16 bit files
    
suggests that the difference between the performance of this code and the
    
old code is negligible (tested only on amd64/linux).

  • ffmpeg : Considers AVPixelFormat as Int ?

    16 mars 2014, par jamie_y

    I would like to use a function ff_load_image.

    program.c

    #include "../ffmpeg/libavfilter/lavfutils.h"
    

    
int main ()
    
{
    
  uint8_t* data;
    

    
  int linesize, width, height, log_ctx;
    

    
  int i = ff_load_image(&data, &linesize, &width, &height, AV_PIX_FMT_RGB24, "blue.jpg", &log_ctx);
    
}

    This compiles, but gives a warning.

    program.c: In function 'main':
    
program.c:11: warning: passing argument 5 of 'ff_load_image' makes pointer from integer without a cast
    
../ffmpeg/libavfilter/lavfutils.h:39: note: expected 'enum AVPixelFormat *' but argument is of type 'int'

    When I run the program, it segment faults. I can't think of any other way to specify a pixel format. Why would ffmpeg think AV_PIX_FMT_RGB8 is an integer ? It's obviously an AVPixelFormat.

  • gcc : Undefined Reference Error

    16 mars 2014, par jamie_y

    I would like to use a function 'ff_load_image' defined in ffmpeg/libavfilter/lavfutils.h.

    program.c

    #include "../ffmpeg/libavfilter/lavfutils.h"
    

    
int main ()
    
{
    
  uint8_t* data;
    

    
  int linesize, width, height, log_ctx;
    

    
  int i = ff_load_image(&data, &linesize, &width, &height, AV_PIX_FMT_RGB24, "blue.jpg", &log_ctx);
    
}

    Running

    gcc -I$HOME/ffmpeg/include program.c -L$HOME/ffmpeg/lib -lavfilter -lavcodec -lavutil

    gives undefined reference errors.

collect2: ld returned 1 exit status

    However, I was successful in running functions in other library, such as the ones in "ffmpeg/libavcodec/avcodec.h". Why is this happening to "ffmpeg/libavfilter/lavfutils.h" ?
