    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 (...)

  • 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" (...)

  • How to calculate avrage PSNR when it contains inf values ?

    15 février 2019, par Talia

    I got PSNR via VQMT, then I found some ’inf’ values in the calculated csv file which I understood it means the frame in the decoded sequence is identical to the original video frame. There are also some values like 111.29. My question here is that what is the max value for PSNR before inf ? because it seems 111.29 is a very high value but they are not the same ! why do I have these big values ?

    At the end of CSV file (contains PSNR for all frames) the average PSNR is written ’inf’. My question is that how should I get the average PSNR ? should I ignore the inf frames and getting the average for the rest ? it is not very accure in my mind ! or I should, for example, replace inf with something like 111.229 and then getting average with it ?

    My question here is I understand 111.229 could be the max threshold when the two frames are identical, but I can’t find any reference for it, if this is right do you know any reference for it ?
