La sauvegarde automatique de canaux SPIP
1 April 2010, byDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -
Script d’installation automatique de MediaSPIP
25 April 2011, byAfin 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.

Automated installation script of MediaSPIP
25 April 2011, byTo 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.

split/select/overlay Buffer queue overflow, dropping
18 August 2015, by basinThis command is a simplified version of the real command. It’s supposed to write 4 seconds of first input into
out0.mkv
and overlay the same first input on top of second input and write the result intoout1.mkv
ffmpeg -y \
-f lavfi -i testsrc=s=640x480:d=10:r=25 \
-f lavfi -i testsrc=s=640x480:d=10:r=25 \
-filter_complex "
[0:v]split=2[in0-0][in0-1];
[in0-0]select='lt(t,4)'[out0];
[1:v][in0-1]overlay[out1]
" \
-map '[out0]' out0.mkv \
-map '[out1]' out1.mkvDuring processing it prints
Buffer queue overflow
and in the end there’s a still image inout1.mkv
.My guess is that one of the nodes in filter graph cannot consume new frames from one input, because it’s waiting for another input, but I don’t understand why.
It looks like
out1
is waiting forout0
, although they should be independent -
