  • 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 (...)

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

    Refactor inter mode rate-distortion search

    This commit separates the rate-distortion optimization loop of
    superblocks from that of sub8x8 blocks. This allows better design
    rate-distortion optimization search loop for each setting. It also
    removes the use of SPLITMV and I4X4_PRED therein.

    No performance change in speed 0 settings. For bus@CIF at 2000kbps,
    the speed 1 runtime goes from 48009ms to 43894ms (about 10% faster).
    The overall compression performance on derf changed by -0.021%.

    Speed 2 runtime goes from 27114ms to 28700ms (6% slower), while the
    overall coding efficiency goes up by 1.629% for derf, 1.236% for yt.

    Enable mode search threshold update in non-RD coding mode

    Adaptively adjust the mode thresholds after each mode search round
    to skip checking less likely selected modes. Local tests indicate
    5% - 10% speed-up in speed -5 and -6. Average coding performance
    loss is -1.055%.
