  • 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" (...)

  • vp3 : Change type of stride parameters to ptrdiff_t

    23 août 2016, par Diego Biurrun
    vp3 : Change type of stride parameters to ptrdiff_t

    This avoids SIMD-optimized functions having to sign-extend their
    
stride argument manually to be able to do pointer arithmetic.
    

    Also adjust parameter names to be "stride" everywhere.

  • vc1dsp : Change remaining stride parameters to ptrdiff_t

    29 mars 2022, par Martin Storsjö
    vc1dsp : Change remaining stride parameters to ptrdiff_t

    The existing x86 assembly for loop filters uses the stride as a
    
full register without clearing/sign extending the upper half
    
of the registers on x86_64.
    

    This avoids crashes if the caller would have passed nonzero bits
    
in the previously undefined upper 32 bits of the parameters.
