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.

Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)

Why does Google Chrome not play one of my mp4 files with H.264 codec, while Firefox does ?
23 mai 2023, par Paul LevyI have two mp4, both with H.264 codecs. One plays in Chrome (I didn't create it) and the other downloads and plays in my computer's video player rather than in-browser. Both play completely fine in Firefox. I've searched and cannot understand how to make it work in Chrome (Version 113.0.5672.126 on Mac). I'm writing the videos with ffmpeg version 4.3.6-0.


Here are the selected ffprobe outputs for the two videos (the first doesn't play in Chrome, the second does) :




Video : h264 (Main) (avc1 / 0x31637661), yuv420p(progressive), 2880x960, 1684 kb/s, 100 fps, 100 tbr, 12800 tbn (default)






Video : h264 (Main) (avc1 / 0x31637661), yuv420p(tv, bt709, progressive), 240x426 [SAR 1:1 DAR 40:71], 20 kb/s, 29.97 fps, 29.97 tbr, 30k tbn (default)




I'm creating the first video with the following flags (merging the audio has no impact) :


ffmpeg -i VIDEO -i AUDIO -c:v copy -af aresample=async=1:first_pts=0 -loglevel error -vcodec libx264 -profile:v main -preset medium -movflags +faststart -pix_fmt yuv420p -y OUTPUT



where I create VIDEO by merging 3 videos horizontally with :


ffmpeg -i VIDEO_1 -i VIDEO_2 -i VIDEO_3 -filter_complex hstack=inputs=3 -loglevel error -vcodec libx264 -profile:v main -preset medium -movflags +faststart -pix_fmt yuv420p -y VIDEO
