Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
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 ;

do not match the corresponding output link in0:v0 parameters (1280x720, SAR 1:1)From what I’ve researched I need to use setsar to force all the videos to be 1:1 before I concat, but I’m not sure how to do that in my filter.

Word-by-word display of subtitles in FFMPEG ?
10 mars 2020, par ThaDonI am trying to burn subtitles into a video such that they appear in a word-by-word fashion instead of all at once.
