Le plugin : Gestion de la mutualisation
2 mars 2010, parLe plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
Installation basique
On installe les fichiers de SPIP sur le serveur.
On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

1er mars 2024, par Tushar GuptaI using the Xabe.FFmpeg package to generate clips from a video. The code is basically converting a video to multiple clips and it's working fine in my local but whenever I am uploading the code to app service the code is not working.

I tried deploying the app service using different OS but still facing the same issue, I also tried using different packages but the result is same.

Rsync a video stream continously and watch it
13 juin 2017, par UralI am recording a cam on a remote machine in my office. I use ffmpeg for that, and writing to mpegts file.
I want to copy that stream locally, to have a fresh copy, and watch it simultaneously.
I don’t know options for rsync to grab a changing (appending) file, so I am using loop for it, and it is very slow.while true; do rsync -avz --progress --partial --append remote:~/myvideo.mp4 ~/; done
For watching, I tried :
mkfifo /tmp/fifo
tail -f ~/myvideo.mp4 > /tmp/fifo
mplayer /tmp/fifoBut because rsync is stopping every 5 sec, it is working unstable.
How to record and stream a remote cam continuously, and use only one network stream for that ?
