    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" (...)

  • x86 : hevc_mc : split differently calls

    x86 : hevc_mc : split differently calls

    In some cases, 2 or 3 calls are performed to functions for unusual
    
widths. Instead, perform 2 calls for different widths to split the
    
workload.
    

    The 8+16 and 4+8 widths for respectively 8 and more than 8 bits can’t
    
be processed that way without modifications : some calls use unaligned
    
buffers, and having branches to handle this was resulting in no
    
micro-benchmark benefit.

  • Revision fee045d13a : Disable adaptive pred filter for non-split mode If sf->disable_split_mask is DI

    24 février 2014, par Yunqing Wang

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_onyx_if.c



    Disable adaptive pred filter for non-split mode

    If sf->disable_split_mask is DISABLE_ALL_SPLIT, disable
    sf->adaptive_pred_interp_filter to avoid unnecessary operations.
