Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...) -

How to make fast video editor on android ? [closed]
7 mai 2022, par Mr MisterI make photo/video editor like an instagram stories editor. I use ffmpeg to encode video on the phone. But it takes too much time. When I encode 30 second full-hd video it takes 1 minute. I use filters like : scale, crop, padding and drawtext.


I tried to divide videos into several parts. But my phone crashes when I try to process more than 2 videos at once.


Instagram encodes video extremely fast. Are there any alternatives to ffmpeg ? I'm currently interested in making video editor for android but I'll need it for IOS too.
