  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • avcodec/ppc/vp8dsp_altivec : Fix out-of-bounds access

    13 mars 2024, par Andreas Rheinhardt
    avcodec/ppc/vp8dsp_altivec : Fix out-of-bounds access

    h_subpel_filters_inner[i] and h_subpel_filters_outer[i / 2]
    
belong together and the former allows the range 0..6,
    
so the latter needs to support 0..3. But it has only three
    
elements. Add another one.
    
The value for the last element has been guesstimated
    
from subpel_filters in libavcodec/vp8dsp.c.
    

    This is also intended to fix FATE-failures with UBSan here :

    avcodec/lossless_videoencdsp : Fix unaligned access

    HAVE_FAST_UNALIGNED being true does not imply that
    
one can simply read from any pointer via *(long*).
    
It is undefined behaviour in case the pointer is not
    
sufficiently aligned ; and even if it is, it is (likely)
    
a violation of the effective-type rules. Fix both
    
of these by using the appropriate AV_[RW]N macros.
    

    Also, the current code used sizeof(long) as if this
    
were the CPU's native arithmetic size, but this is
    
not true on 64bit Windows. This has been fixed, too.
    

    This affected huffyuv FATE-tests.

  • lavu/opt : distinguish between native and foreign access for AVOption fields

    3 mars 2024, par Anton Khirnov
    lavu/opt : distinguish between native and foreign access for AVOption fields

    Native access is from the code that declared the options, foreign access
    
is from code that is using the options. Forbid foreign access to
    
AVOption.offset/default_val, for which there is no good reason, and
    
which should allow us more freedom in extending their semantics in a
    
compatible way.
