    On ne revendique pas d’être les seuls à faire ce que l’on fait ... et on ne revendique surtout pas d’être les meilleurs non plus ... Ce que l’on fait, on essaie juste de le faire bien, et de mieux en mieux...
    La liste suivante correspond à des logiciels qui tendent peu ou prou à faire comme MediaSPIP ou que MediaSPIP tente peu ou prou à faire pareil, peu importe ...
    On ne les connais pas, on ne les a pas essayé, mais vous pouvez peut être y jeter un coup d’oeil.

  • Anomalie #3371 : faille sécurité ? balise meta+refresh dans un champ d’article

    5 janvier 2015, par Fabien Abbadie

    Fil Up a écrit :

    Pour moi le problème de sécu vient du piratage qui a eu lieu, pas de ce que le pirate a fait une fois dans la place... Essentiellement il est passé admin, et les admins gardent le droit de faire des choses intéressantes dans leur site.

    Oui mais non : j’ai testé sur une 3.0.17 à jour, pas piraté, et a priori, n’importe quel rédacteur peut faire ça.
    J’ai même testé sur forum.spip.net et ça a l’air de le faire aussi fait : mettez en titre, et voyons si les utilisateurs sont contents quand ils sont renvoyés vers une page piégé à chaque fois que l’article est listé.

    Si vous pouvez, essayez de voir cet article, proof of concept : http://forum.spip.net/ecrire/?exec=article&id_article=3140

  • Anomalie #4052 (Nouveau) : Visualiser ses messages dans le privé

    28 novembre 2017, par tcharlss (*´_ゝ｀)

    Dans la page infos_perso du privé (ou sur sa page d’auteur), il y a un lien dans la boîte d’infos qui mène vers controler_forum, avec le nombre de contributions : « N messages de forum ».

    Intuitivement on s’attendrait à ce que le lien nous mène vers une page qui montre nos messages, mais ce n’est pas le cas, on les voit tous.
    Je propose de rajouter id_auteur=N au lien.

    Ensuite sur cette page, la gestion des auteurs est un inconsistente avec le reste.
    À la base les liens pour filtrer les messages et les boutons d’actions sont situés dans la boîte de raccourcis à gauche.
    En revanche il n’y a pas moyen de filtrer ses propres messages (à part manuellement en ajoutant id_auteur dans l’URL), et une fois qu’un auteur est sélectionné, l’info apparaît dans une boîte au dessus de la liste, au lieu d’utiliser la boîte de raccourcis à gauche. Donc l’interface permet de « défiltrer » par auteur mais pas de filtrer.

    Je propose donc d’ajouter un filtre « mes messages » dans la boîte de raccourcis.

  • How to calculate vmaf score of multi-resolution webm using ffmpeg ?

    13 juillet 2022, par will

    I’m trying to calculate the vmaf of two videos, one is avi(rawvideo(I420), yuv420p), the other is webm(vp8, yuv420p). I uploaded test video and vmaf log here.

    


    But I found that if it’s a multi-resolution webm, the scores obtained with and without fps filter are quite different. Without fps filter the vmaf score is 34.670390, with fps filter the vmaf score is 56.339923.

    


    If it‘s a single resolution webm, there is no significant difference between the scores obtained with and without fps filter. Without fps filter the vmaf score is 65.527304, with fps filter the vmaf score is 65.480217.

    


    I use these commands.

    


    without fps filter
