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.

mute audio if the volume *exceeds* a threshold
15 February 2023, by a1s2d3f4So, I have spent quite a bit of time looking for the answer but I get the exact opposite (something I already know how to do), namely, the audio below a certain threshold can get muted (can be done either with ffmpeg or sox).


What I need is for the command to search my audio for anything that exceeds -18dB and mute all such segments. (The reason for this is because I have a recording where I am playing an electric piano with the audio output being recorded directly through the cable, but I am also recording from two microphones what I am speaking - between my playing. When I am playing the keyboard, the mics pick up a lot of action noise which I want to mute, and that's easy to do because the channel that records my piano input has piano sounds at that point and that corresponds exactly with when I want the audio from my mics to be muted, or at least attenuated.)


Does anyone know if such a feat is possible?
If it cannot be done with just one command, that's fine I'll try anything.

ffmpeg select filter starting time?
8 March 2021, by Sergey YermakI am stuck with ffmpeg select filter.


I am trying to generate 10 thumbnails from the video and it works fine.


However, I want to skip some starting time (around 30 seconds), since there are usually video intros, etc.


So I can't figure out a way to do that - not using ffmpeg too often.
The command I'm currently using:


ffmpeg -loglevel panic -y -i "test.mp4" -frames 1 -q:v 1 -vf "select=not(mod(n\,7877)),scale=-1:227,tile=10x1" video_preview.jpg
