Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs
12 avril 2011, parLa manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras. -
Que fait exactement ce script ?
18 janvier 2011, parCe script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
Installation de dépendances de MediaSPIP
Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :
Les outils de base pour pouvoir installer le reste des dépendances Les outils de développements : build-essential (via APT depuis les dépôts officiels) ; (...)

Make a video in sequential order from frames
11 septembre 2021, par shailzaI have saved images in the sequential format- 0.jpg, 1.jpg, ---,99.jpg, 100.jpg. I am making video from these frames by using ffmpeg for conversion :


cmd1 = 'ffmpeg -framerate 25 -pattern_type glob -i "/home/ubuntu/17/1_1/*.jpg" /home/ubuntu/17_a.avi'


But ffmpeg is not reading the images in sequential manner. How to make a video that take frames in a sequential order.

Thanks for you help very much !!!


I tried to run the command alone, then for a long time the program did not return, and after using ctrl+c it reported the following error：

compile ffmpeg report "libprotokit.a : No such file or directory"
5 juillet 2022, par razvanOn kubuntu 21.04 I successfully compiled ffmpeg from latest snapshot.


Now I try to add "—enable-libzmq" to configure command :

 --prefix="$HOME/.ffmpeg/build" \
 --pkg-config-flags="--static" \

I have this libprotokit.a in

Why configure does not find this library ?
