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.

Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

avconv stops streaming after some time
4 juin 2014, par Dhrumil DoshiI am using raspberry-pi board and a usb camera attached with it. i use avconv tool to capture live video from camera and streaming it on network using rtp protocol.
My command on server(raspberry-pi board) is as below :
avconv -f video4linux2 -s 160x120 -i /dev/video0 -vcodec mpeg2video -r 25 -pix_fmt yuv420p -me_method epzs -b 2600k -bt 256k -f rtp rtp ://192.168.1.141:8554
streaming works successfully using this command. Here IP address 192.168.1.141 is the ip address of my client pc. i can play live streaming on client side using vlc successfully.
But Issue is after some time encoding and streaming on server stop automatically. And command hangs there.
Output on server is as below :
$ avconv -f video4linux2 -s 160x120 -v debug -i /dev/video0 -vcodec mpeg2video -r 25 -pix_fmt yuv420p -me_method epzs -b 2600k -bt 256k -f rtp rtp://192.168.1.141:8554
