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 ;

FFMPEG output duration using "-t" is too long by 10 ms
9 octobre 2018, par Ze'evI’m using this command to take video from a 35 second QuickTime file and replace audio with a WAV :
ffmpeg -i 'video.mov' -i 'audio.wav' -c:v copy -c:a copy -map 0:v:0 -map 1:a:0 -t 35.0000 'output.mov'But the audio is slightly longer than the video, and I’m trying to make ffmpeg trim the output to exactly 35 seconds with
-t 35but the output is 35.01 seconds.I also tried
-t 35.000and-to 35and several other options, but it’s alway 10ms too long.ffmpegoutput :ffmpeg version N-91789-g11cec34829 Copyright (c) 2000-2018 the FFmpeg developers
