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 (...) -
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.

Script d’installation automatique de MediaSPIP

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.

FFMPEG - latest build doesn't work, earlier build does
21 juin 2020, par rossmcmI have been using FFMPEG to overlay coloured rectangles on a video. I updated FFMPEG and it no longer works. No error is issued, it just doesn't do the job - the resulting video is the same as the input video. Here's the script :


FFMpeg -y -i Input.mp4 -filter_complex \
 "nullsrc=size=1920x1080, \
 drawbox=x=200:y=100:w=300:h=150:t=20:c=yellow, fade=in:st=10:d=1:alpha=1, fade=out:st=20:d=2:alpha=1 [tmp1]; \ 
 nullsrc=size=1920x1080, \
 drawbox=x=240:y=140:w=300:h=150:t=20:c=red, fade=in:st=15:d=1:alpha=1, fade=out:st=25:d=2:alpha=1 [tmp2]; \
 [tmp1][tmp2] overlay=0:0:shortest=1[tmp3]; \
 [0:v][tmp3] overlay=0:0:shortest=1" \
 Output.mp4


The output video should be the input video with a yellow rectangle added from T=10 to T=20 and a red rectangle from T=15 to T=25, fading them in and out.


The version that was working (3.4) was one that came with an ImageMagick installation. The version I updated it to was 4.2.3. I tried it on various other builds I had lying around and it only works with 3.4.


It seems unlikely that this is a regression so I haven't submitted a bug report. I figure it's more likely that I'm not doing something correctly and 3.4 is more lenient on its interpretation of my command.


Whatever, I prefer to be working with a current build, so I invite comments on what the reasons might be.

FFMPEG does not add images to audio
20 février 2018, par GooglebotI want to create a slideshow with a background music by
ffmpeg, and use the commandffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4and map.txt is like
file '1.jpg'
duration 15
file '2.jpg'
duration 60The result is a video with the audio and blank background. If I run the above command without audio as
ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4a perfect video of the images (the intended slideshow) is generated (but obviously without audio).
I reckon the problem is related to synchronising the audio and images.
This is the terminal output for the first command
ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4
