  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang 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.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

    Use non-zero mode threshold for NEARESTMV modes

    This commit makes the encoder to use non-zero mode threshold for
    NEARESTMV modes. The runtime for test clips of speed 3 is reduced
    by about 1%.

    Skip certain ALTREF inter modes in ARF coding

    This commit enables the encoder to skip checking ALTREF inter modes
    in ARF coding, if the predicted motion vectors suggest that the
    GOLDEN_FRAME provides higher prediction accuracy than ALTREF_FRAME.

    It improves the speed 3 encoding speed by about 5%, at the expense
    of compression performance loss -0.041% and -0.225% for derf and
    stdhd, respectively.
