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 (...) -
Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

avformat/mov : Add option to ignore chapters during parsing
10 novembre 2015, par Bryan Huhavformat/mov : Add option to ignore chapters during parsing
Chapter-indexing can be expensive since chapters may be interspersed

costly when consuming a video over a remote protocol like http.
Furthermore it is often unnecessary, especially when only trying to get
video info (e.g. via ffprobe).Signed-off-by : Michael Niedermayer <michael@niedermayer.cc>

ffmpeg creating mp4 vs mp4
23 octobre 2015, par user1207446I have two mp4 files. One of them was given to me and plays well under mediawiki (using the MediawikiPlayer extension). The other I created from a WMV file and it does not play. When I look at the two files through the eyes of ffprobe, they appear to be very different. The working file returns this :
