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 :

La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -
Mise à disposition des fichiers
14 avril 2011, parPar défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.
Cependant, il est possible et facile d’autoriser les visiteurs à avoir accès à ces documents et ce sous différentes formes.
Tout cela se passe dans la page de configuration du squelette. Il vous faut aller dans l’espace d’administration du canal, et choisir dans la navigation (...)

How to stream live video from DJI Professional 3 camera ?
29 avril 2017, par raullalvesI have to get the live stream video from DJI Phantom 3 camera in my C++ application, in order to do a Computer Vision processing in OpenCV.
First I tried sending the H264 raw data through an UDP socket, inside this callback :
mReceivedVideoDataCallBack = new CameraReceivedVideoDataCallback() {
@Override
public void onResult(byte[] videoBuffer, int size) {
//Here, I call a method from a class I created, that sends the buffer through UDP
if (gravar_trigger) controleVideo.enviarFrame(videoBuffer, size);
if (mCodecManager != null) mCodecManager.sendDataToDecoder(videoBuffer, size);
}
};That communication above works well. However, I haven’t been able to decode that UDP H264 data in my C++ desktop application. I have tested with FFmpeg lib, but couldn’t get to alocate an
AVPacket
with my UDP data, in order to decode usingavcodec_send_packet
andavcodec_receive_frame
. I also had problems withAVCodecContext
, since my UDP communication wasn’t a stream like RTSP, where it could get information about its source. Therefore, I had to change how I was trying to solve the problem.Then, I found libstreaming, in which can be associate to stream the android video camera to a Wowza Server, creating something like a RTSP stream connection, where the data could be obtained in my final C++ application easily using OpenCV
videoCapture
. However, libstreaming uses its ownsurfaceView
. In other words, I would have to link the libstreamingsurfaceView
with the DJI Drone’svideoSurface
. I’m really new to Android, so don’t have any clue of how to do that.To sum up, is that the correct approach ? Someone has a better idea ? Thanks in advance
