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 :

MediaSPIP : Modification des droits de création d’objets et de publication définitive
11 novembre 2010, parPar défaut, MediaSPIP permet de créer 5 types d’objets.
Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...)

Why won’t this mp4 play in a video-js tag any longer
18 octobre 2019, par VelocedgeI’m using ffmpeg to convert files to MP4. I’ve made some modifications to the ffmpeg string but now it seems no matter what I use, the video won’t play in an HTML5 tag (Chrome browser). Normally, I just used "-vcodec libx264 -s 1280x720 -ar 22050". When I try to load it in the video tag, I get the following error on http://family.gotsport.net/lmw/GotSport/videoPlayer.asp?WS=1&URL=/VideoFiles/2/4_70_highlight :
The media could not be loaded, either because the server or network failed or because the format is not supported.No matter what parameters I use (or don’t use), it still won’t play. However, if you just call the url directly, it will play in Chrome (http://family.gotsport.net/videofiles/2/2_70_highlight.mp4). I’m using the 7.0.0 version of video-js from their CDN (although older versions give the same result).
Video tag looks like :
<video class="video-js vjs-default-skin" autoplay="autoplay" controls="controls" preload="auto">
<source src="/VideoFiles/2/4_70_highlight.mp4" type="video/mp4"></source>
</video>Here is the MediaInfo output from the file that won’t play :
