  • 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 (...)

  • x86inc : AVX-512 support

    x86inc : AVX-512 support

    AVX-512 consists of a plethora of different extensions, but in order to keep
    
things a bit more manageable we group together the following extensions
    
under a single baseline cpu flag which should cover SKL-X and future CPUs :
    
 * AVX-512 Foundation (F)
    
 * AVX-512 Conflict Detection Instructions (CD)
    
 * AVX-512 Byte and Word Instructions (BW)
    
 * AVX-512 Doubleword and Quadword Instructions (DQ)
    
 * AVX-512 Vector Length Extensions (VL)
    

    On x86-64 AVX-512 provides 16 additional vector registers, prefer using
    
those over existing ones since it allows us to avoid using `vzeroupper`
    
unless more than 16 vector registers are required. They also happen to
    
be volatile on Windows which means that we don't need to save and restore
    
existing xmm register contents unless more than 22 vector registers are
    
required.
    

    Big thanks to Intel for their support.

    avcodec/mips : Improve hevc uni weighted vert mc msa functions

    Pack the data to half word before clipping.
    
Use immediate unsigned saturation for clip to max saving one vector register.

    avcodec/dca_parser : improve frame end search

    Parse core frame size directly when searching for frame end instead of
    
using value extracted from previous frame.
    

    Account for unused bits when calculating sync word distance for 14-bit
    
streams to avoid alias sync detection.
    

    Parse EXSS frame size and skip over EXSS frame to avoid alias sync
    
detection.
