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. -

Android RTSP to v4l2 device
16 mars 2016, par user2060733I have created an application that takes an RTSP stream and displays it SurfaceView. This is straightforward enough. However I was wondering if it was possible to take an RTSP stream in Android and use it to create a v4l2-device in the same way connecting a webcam does at a location such as /dev/video0.
Can this be done using a compiled version of FFMPEG for Android or perhaps a simpler method ?
Any direction on this would be greatly appreciated !

If you have an idea to solve this, let me know.
