Soumettre améliorations et plugins supplémentaires
10 avril 2011Si vous avez développé une nouvelle extension permettant d’ajouter une ou plusieurs fonctionnalités utiles à MediaSPIP, faites le nous savoir et son intégration dans la distribution officielle sera envisagée.
Vous pouvez utiliser la liste de discussion de développement afin de le faire savoir ou demander de l’aide quant à la réalisation de ce plugin. MediaSPIP étant basé sur SPIP, il est également possible d’utiliser le liste de discussion SPIP-zone de SPIP pour (...) -
Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.
Modification lors de l’ajout d’un média
Lors de l’ajout d’un média de type "image" un nouveau bouton apparait au dessus de la prévisualisation (...) -
Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

Using ffmpeg with Python 2.7
1er juillet 2015, par suffaI have been trying to install pyffmpeg in Python 2.7 unsuccessfully. I found a package for Python 2.6, but I can’t get it to work. So, I have been mulling around with 2.7. I’ve seen previous post from others on this site, but they have not helped. Does anyone have experience with this. Ultimately, I want to develop an wxPython app that converts video formats. Thanks
Code that I ultimately wrote that worked for me (very rudimentary, but it works ....) :

Anomalie #3180 (Nouveau) : Url propre et rubrique numérique
6 mars 2014, par Debondt DidierHello,
Lorsque l’on utilise les URL propres, et que l’on nome un objet de manière numérique (2012 par exemple), SPIP génère une URL de type domaine.tld/2012 qui est buggé.
J’ai testé avec URL propre, mais cela doit aussi se produire dans d’autre mode d’URL. L’idéal serait sans doute de ne jamais avoir des URL uniquement numériques.

How do I prevent Quality loss in the beginning of a video ?
25 mars 2012, par Adam IngmanssonMy company transcodes videos sent in by users (recorder by our own screenrecording software)
I use FFMpeg to do the work using this command :
/ffmpeg/ffmpeg -i in.mov -vcodec libx264 -fpre /ffmpeg/ffpresets/libx264-slower.ffpreset -y out.flvThe purpose is to prepare the video for viewing in browser.
The problem is that the first 10, or so, seconds the quality is really poor.
What can cause this ? and how can i fix it ?
