  • Evolution #4712 : Mettre à jour la lib Yaml qui est dans le plug, ou faire ça en JSon

    23 avril 2021, par Eric Lupinacci

    Je viens de faire une branche nommée json qui implémente une version JSON des wheels.
    C’est en cours de tests mais l’article qui regroupe la type de tinytypo par exemple renvoie exactement le même résultat qu’en YAML.
    Pour l’instant il faut choisir json ou yaml mais je vais essayer de faire en sorte que le json soit choisi par défaut et si pas de wheel en json qu’on se rabatte sur le YAML si le plugin YAML est activé.

    Je sais que c’est pas forcément un must pour la 4.0 mais au moins ça permet d’avoir ça en magasin.

  • why it is taking a lot of time to convert image via HTTP to video in ffmpeg ?

    20 avril 2021, par al pacino

    Below is the ffmpeg i am using to convert images into videos but It is taking around 3 minutes to convert image to 5 second video.
If I run the command on Image present on a directory then it converts images to videos very swiftly.

    


    can anyone tell what I am doing wrong ?
