  • MediaSPIP v0.2

    21 juin 2013, par

    MediaSPIP 0.2 est la première version de MediaSPIP stable.
    Sa date de sortie officielle est le 21 juin 2013 et est annoncée ici.
    Le fichier zip ici présent contient uniquement les sources de MediaSPIP en version standalone.
    Comme pour la version précédente, il est nécessaire d’installer manuellement l’ensemble des dépendances logicielles sur le serveur.
    Si vous souhaitez utiliser cette archive pour une installation en mode ferme, il vous faudra également procéder à d’autres modifications (...)

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Synchronization between camera video and inertial sensor data

    14 janvier 2013, par Dima Bobby

    I need to :

    write an Android real-time data logging application employing camera video and polling other sensor (accelerometer, gyro, compass) data at high rates e.g. 50 Hz and writing this information into file. As these data will later be used for navigation, precise synchronization between different data is extremely important.

    What I have done :

    implemented sensor polling in native code, so that less Java execution overhead is employed. Nonetheless, camera encoding is still in Java, for this I tried MediaRecorder and MediaCodec. In both cases data from inertial sensors and camera are not synchronized between each other, there is a varying delay of about 400ms and this is inacceptible. Moreover, I am pretty sure that encoding is HW accelerated. Now, to reach my goal I am considering about going for native implementation of video encoding using either OpenCV or FFMPEG (native code is expected to be more efficient).

    EDIT : I have even tried saving the image uncompressed as pgm file, but this way the image data get really huge in size and the FPS is really low, so we are losing data. I suspect that file writing process is the bottleneck in this case. Is there an efficient way to save raw data to file achieving high FPS ?

    Any hints what I should go for to achieve my goal ? I am using Android Jelly Bean with Asus Transformer TF700 Infinity.

    Dmitriy
