  • 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" (...)

    vp9 decoder : row-based multi-threaded loopfilter

    Implemented parallel loopfiltering, which uses existing tile-
    decoding threads. Each thread works on one row, and when that row
    is loopfiltered, it moves to next unattended row. To ensure the
    correct filtering order, threads are synchronized and one
    superblock is filtered only if the superblocks it depends on are
    filtered already.

    To reduce synchronization overhead and speed up the decoder, we use
    nsync > 1 for high resolution.

    Performance tests :
    1. on desktop :
    8-tile 4k video using 8 threads, speedup : 70% - 80%
    4-tile HD video using 4 threads, speedup : 35%
    2. on mobile device(Nexus 7) :
    4-tile 1080p video using 4 threads, speedup : 18% - 25%
    4-tile 1080p video using 2 threads, speedup : 10% - 15%

    ffv1 : add a Vulkan-based decoder

    This patch adds a fully-featured level 3 and 4 decoder for FFv1,
    
supporting Golomb and all Range coding variants, all pixel formats,
    
and all features, except for the newly added floating-point formats.
    

    On a 6000 Ada, for 3840x2160 bgr0 content at 50Mbps (standard desktop
    
recording), it is able to do 400fps.
    
An Alder Lake with 24 threads can barely do 100fps.
