  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

    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_ethread : the tile-based multi-threaded encoder

    Currently, VP9 supports column-tile encoding, which allows a frame
    to be encoded in multiple column tiles independently. The number of
    column tiles are set by encoder option "—tile-columns". This
    provides a way to encode a frame in parallel.

    Based on previous set of patches, this patch implemented the tile-
    based multi-threaded encoder. Each thread processes one or more
    tiles.

    Usage :
    For HD clips :
    — tile-columns=2 —threads=1/2/3/4

    While using 4 threads, tests showed that the encoder achieved
    2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at
    realtime speed 5.

    Preliminary code for variance based paritioning

    Brings back most of Jim's previous patch for choosing
    partitioning based on variance while making it compatible
    with the current state of the code. Also adds a
    nonrd_use_partition() function to recursively encode for any
    arbitrary sb_type decisions within a 64x64 block ; and
    includes some refactoring.

    Currently, when the VAR_BASED_PARTITIONING mode is turned on
    for speed 7, there is a 10+% speed-up observed.

    Experiments/improvements with this new partitioning method
    will be conducted subsequently.
