  • Récupération d’informations sur le site maître à l’installation d’une instance

    26 novembre 2010, par

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • FFMPEG - Green cast with Splash image in video

    30 mai 2020, par rossmcm

    I'm using FFMPEG to produce a video consisting of a single monchrome JPG image :

    



    ffmpeg -y -loop 1 -framerate 30 -t 5 -i SplashBW.jpg Splash.mp4


    



    There are two issues with the resulting video :

    



      

    • When viewed with VLC it has a green cast

      • 


    • When viewed with "Film and TV" (I suspect this is the Windows 10
viewer - the association for MP4 files seems to have been hijacked
on my PC) it has a green cast and a predominant flickering every
0.5 seconds or so.

      • 


    



    When viewed with Irfan View it looks fine. I don't know whether the issue is with the original JPG, the FFMPEG command, or the viewers. Naturally, I want it to render properly on all outputs.

    



    The first two links below look fine in my browser (Chrome) when I open them. The third link is a screen recording of what I see when I try to play the video with the Film and TVapp.

    



    B&W image
