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.

La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans 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 (...)

classes.jar not getting generated in .aar file
20 septembre 2016, par vasanthI am using Android Studio AI-141.216xxx.
I generated a .aar file from FFMPEG module/library from this project :
https://github.com/WritingMinds/ffmpeg-android-javaI then tried to import a .aar locally into a module in some other application.
imports were failing.
But, when I checked in the ’generated’ folder,
I see that classes.jar is empty.Would you know why this is happening ? Any pointer is highly appreciated.
Thanks in advance. -
RecordRTC only recording stop after 1min
2 novembre 2015, par Mick JackI am using RecordRTC to record a webcam stream and using ffmpeg to convert the output into .mp4 recording of 1min video is fine and the browser merge both the audio and video into a single .mp4 however recording that is longer than 1min will encounter this error.

Compile OpenCV3 with Cuda7.5 ffmpeg (latest) issue OpenSUSE 13.2
23 janvier 2016, par IngeborgI am using an OpenSUSE 13.2-X86-64 and a Geforce 940M GPU. I want to work with it on the Qt5 IDE.
For this purpose, i have installed my GPU Driver with the Cuda7.5 toolkit rpm from the cudazone. Everything is nearly fine.
It detects everything I have made and executed a couple of the cuda samples.As next step, i have installed the current FFmpeg version with nvenc and other libraries like Xvid and many of
the other usefull stuff which would be to much to list it here. After that i have downloaded the current
OpenCV-3.0.0 source code and ran cmake-gui where i have added cuda, ffmpeg, Qt5 etc and maked it.On different points of the make session (make -j4) i get this kind of mistake from my console (The list of the Multiple definition
error is much longer). This is the first one..
