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.
La documentation de l’utilisation du script d’installation (...) -

Vertical video subtitles burn font size
20 mai 2020, par fantomI have two videos, one of them is has display aspect ratio (DAR) 16:9 (horizontal) and another one has 9:16 (vertical). I need to burn in subtitles into them, and for horizontal video I need to set Fontsize=18. But if I try to use the same settings with vertical video, I get very big text size, so I need to set Fontsize=10 to get the same size of letters as in horizontal video.
The question is, why I get different displayed font sizes for different DAR and is there any way to have one settings for both (I don't know up front which orientation video will have when burning subtitles and want to not depend on it)

Issue with openh264enc gstreamer plugin and tcp connections
20 septembre 2016, par agaldosI am trying to stream over TCP encoded video into a EC2 Instance. Using "x264enc" encoder, all works correctly. I get the frames and generate the video correctly.
The issue comes when I try to use the "openh264enc" encoder.
If I put in the server "nc -l -p 5555" I can check that data is arriving into the port but when I put the pipeline goes to PREROLLING state and nothing more happens. If I cut the process in the sender, this message appears in the server :

How can I combine two audios into one, but using the length of the first audio ?
21 avril 2021, par vaginatorZalupiThere are two audios. I need to connect them to each other (two channels), but with the same length as the first. I found a command on Stack Overflow that partially solves my problem :
ffmpeg -i AgAD3RMAAvgr.ogg -i audio.mp3 -filter_complex amix=inputs=2:duration=longest output.mp3
