  • 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 (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • How to get animated webp file with transparent background padding after converting from mp4 file with ffmpeg ?

    2 mars 2024, par isharth rastogi

    I need to convert mp4 video(1280×720) to webp file(512x512) such that the resulting webp file maintains aspect ratio and also gets entirely contained in 512x512 and the uncovered areas at the top and bottom should be transparent.

    


    I tried the following ffmpeg command :

    


    ffmpeg -i sample.mp4 
-vcodec libwebp -filter:v fps=fps=20 -lossless 1 -loop 0 -preset default -an -vsync 0 -vf 
scale=512:512:force_original_aspect_ratio=decrease,pad=512:512:-1:-1:color=#00000000 sample.webp


    


    In the above command please note pad=512:512:-1:-1:color=#00000000
I have given the alpha values 00 but it outputs black color only.

    


    I also referred to this site https://ffmpeg.org/ffmpeg-utils.html#color-syntax It says

    


    


    It can be the name of a color as defined below (case insensitive match) or a 0xRRGGBB[AA] sequence, possibly followed by @ and a string representing the alpha component.
The alpha component may be a string composed of "0x" followed by a hexadecimal number or a decimal number between 0.0 and 1.0, which represents the opacity value (‘0x00’ or ‘0.0’ means completely transparent, ‘0xff’ or ‘1.0’ completely opaque). If the alpha component is not specified then ‘0xff’ is assumed.

    


    


    I tried both color=0x000000@0x00 and color=0x000000@0.0 but the result was opaque black.
