Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -
Le profil des utilisateurs
12 avril 2011, parChaque utilisateur dispose d’une page de profil lui permettant de modifier ses informations personnelle. Dans le menu de haut de page par défaut, un élément de menu est automatiquement créé à l’initialisation de MediaSPIP, visible uniquement si le visiteur est identifié sur le site.

Android FFmpeg Video Recording Delete Last Recorded Part
17 avril 2015, par user3587194I’m trying to do exactly what this picture shows.
Anyway, how can I delete part of a video ? The code I was testing is on github.
It uses a progress bar so that when you record the progress bar will move, and keep them in separate segments. What is confusing to me is trying to figure out where and how to grab each segment to see if I want to delete that segment or not.

How does the dataflow look like in case of using ffmpeg and ffserver ?
6 mai 2015, par randomuser1I can capture the camera image by ffmpeg and send it to ffserver, but what happens next with the data ? Can I collect it on the other site with some other client that uses ffmpeg (e.g. some c# wrapper for it) ? If so - how exactly does the data look like and how can I present it to the final user ? Can I just display the data on display port ? Or is there some other controller for that ?
Thanks !
