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.

Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

Converting AC3 to AAC with minimal loss [on hold]
20 juin 2016, par forthriniPad does not seem to support the ac3 audio codec.
Therefore, I am converting an
mkv/h264/ac3
movie intom4v/m264/aac
usingffmpeg
to view it on the iPad.The video part is simply copied as it is ; my question is how I preserve the audio as best possible.
-
Is there any way to do the audio conversion losslessly ?
-
If no to question 1, what is the best way to preserve the audio quality ? If the source audio is 192 kb/s and 48000 Hz, should I simply use 192/48000 for the target too ? Or will I preserve the audio better if I increase the the bit rate somewhat ?
-
Side question : I noticed that a lot of mkv files have rather poor audio to begin with. Will the loss of ac3/aac re-encoding be negligable compared to the initial quality loss from the source material ? And why isn’t high audio quality more of a priority for movie files ? It’s not like file sizes matter much anymore with today’s storage and bandwidth.
