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 (...) -
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.

Automated installation script of MediaSPIP

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.

When using ffplay, how to eliminate milliseconds from timestamp display in the video-filter
13 mai 2021, par DaveSo when specifying a video-filter to display current video-time in 'hms' layout, the filter appends a millisecond value after the seconds-field.
I want to eliminate the milliseconds portion.


So far, my invoked cmd looks like :


ffplay myfile.mp4 -vf "drawtext=text='%{pts \: hms}':fontsize=20:fontcolor=white: box=1: boxcolor=black"


i.e. instead of : 00:00:01.001 I want just 00:00:01 to display.


[One might have thought that there would exist an 'hmsm' for the former,
and that 'hms' would be the latter, but it just doesn't work that way.] (sigh)

-i C:\VID\test3.mp4
-i C:\VID\test4.mp4
-i C:\VID\test5.mp4
-i C:\VID\background.jpg
-filter_complex
" nullsrc=size=1280x720 [base];
[0] setpts=PTS-STARTPTS, scale=560x360 [video0];
[1] setpts=PTS-STARTPTS, scale=280x180 [video1];
[2] setpts=PTS-STARTPTS, scale=280x180 [video2];
