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 ;
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 - Merge mp4 files and audio file
4 octobre 2016, par Jon StevensI have an ffmpeg that merges 3 mp4 videos and then another command that adds audio to the output file from the first command. The commands are as follows :
ffmpeg -i vid-1.mp4 -i vid-2.mp4 -i vid-3.mp4 -filter_complex "[0:v][1:v][2:v]concat=n=3:v=1" -preset ultrafast -crf 1 output.mp4
ffmpeg -i output.mp4 -i audio.mp3 -preset ultrafast -crf 1 final.mp4- vid-1.mp4 (does NOT have audio stream)
- vid-2.mp4 (does NOT have audio stream)
Is there anyway to do this in one command ? I would like to also add the audio to the video that is getting created in the first command. Is this possible ?
Console output of "ffmpeg -i vid-1.mp4 -i vid-2.mp4 -i vid-3.mp4 -i audio.mp3"
[jstevens@jr testing]$ ffmpeg -i vid-1.mp4 -i vid-2.mp4 -i vid-3.mp4 -i audio.mp3

Anomalie #3535 : liste des rédacteurs connectés
13 octobre 2016, par guytarr °Pierre KUHN a écrit :
Frank, c’est aussi le cas en 3.0.29 ou la valeur par défaut est vide.
Je viens de tomber sur ce cas lors d’une montée de version 2.1 à 3.0.
En 2.1, avec imessage vide, on apparaît dans la liste des connectés. Du coup, pour conserver le comportement sans rien touché, que pensez-vous de peupler à "oui" lorsque la valeur n’est pas "non" pour les 1comite et 0minirezo, afin de suivre la même logique ? c’est ce que j’ai fait pour ma part.
en 3.0 et 3.1 la résultat de la boucle(#VAL’Y-m-d H:i:s’|date(#VAL’-15 minutes’) !par en_lignepagination 10’, ’>(#ID_AUTEUR">#NOM[  ;... (#GRAND_TOTAL|>10|oui) ([(#GRAND_TOTAL|objet_afficher_nbauteur)]) ]

Chrome, ffmpeg, and ogg
13 novembre 2016, par portonWe need to convert mp4 into ogg by ffmpeg (or maybe some other converter) in such a way that the ogg file to be compatible with Chrome browser.
The command like
ffmpeg -i x.mp4 x.oggproduces an ogg file which does not work in Chrome.
ffmpeg -i video_mp4_01_vlublennaya_mama.mp4 x.ogg 2>&1 | tee log.txtproduces
