Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Issues with processing media on windows Azure
23 septembre 2015, par Ahmed MujtabaI have a website built on ASP.NET web forms that works as a media portal for users to upload videos. I’m using ffmpeg encoders to produce video contents to be streamed in the browser. I’m using the web deploy method to publish the site on the Azure server. The website get’s deployed properly however I get following issues in the live site.
-
Video never get’s encoded and published. I get some sort of error.
-
Video get’s published but the process of uploading and encoding the video is way too slow on the web server.
My project solution contains upload.ashx that handles the upload requests and makes the call to encode.ashx which is responsible for the encoding and publishing of the videos. I tried to remotely debug the site but the debugger never get’s to encode.ashx.
I was wondering if these issues can be resolved by having the website deployed with a VM ?
