  • 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" (...)

    avio : Add an internal function for reading without copying

    As long as there is enough contiguous data in the avio buffer,
    
just return a pointer to it instead of copying it to the caller
    
provided buffer.

  • Overriding internal C functions in ffmpeg

    2 août 2013, par ronag

    I have a C++ application which uses ffmpeg.

    What I want to do is to replace the thread based filter execution with my own task-scheduler based execution.

    However, as soon as I try to call a function pointer in my "custom" function I get an access violation, even if the "custom" function is exactly the same as what is in ffmpeg.

    What could cause this ? Some kind of calling convention thing ?

    e.g.

    struct AVFilterInternal {
    
    int (*execute)(AVFilterContext *ctx, int (*func)(AVFilterContext *ctx, void *arg, int jobnr, int nb_jobs), void *arg,
    
                   int *ret, int nb_jobs);
    
};
    

    
static int custom_execute(AVFilterContext *ctx, int (*func)(AVFilterContext *ctx, void *arg, int jobnr, int nb_jobs), void *arg,
    
                           int *ret, int nb_jobs)
    
{
    
    int i;
    

    
    for (i = 0; i &lt; nb_jobs; i++) { // MY goal is to have this as tbb::parallel_for
    
        int r = func(ctx, arg, i, nb_jobs); // Access Violation. If I replace "func" with an inline implementation everything works fine.
    
        if (ret)
    
            ret[i] = r;
    
    }
    
    return 0;
    
}
    

    
void init()
    
{
    
     /* Create filter graph */
    

    
     // For each filter in filtergraph
    
     reinterpret_cast(filter->internal)->execute = custom_execute;
    
}
