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.

Need someone to write a batch shell script to watermark videos via ffmpeg [closed]
21 janvier 2021, par Shiv NandanI am using a batch shell script on windows server to watermark videos


for %%a in ("X:\input older\*.mp4") do ffmpeg -i "%%a" -vf "movie=watermark.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]" "X:\output folder\%%~na.mp4"
pause


It converts all videos from input folder to output folder. I want to...


- 

- Change watermark location after every 10 seconds in video for all videos.
- Water mark size is perfect when video resolution is 19201080 but its different for low resolution video for example : 1280720 its large, and for 640*360 extra large. So I want to keep the water mark size fixed.

The command I am running is
