  • 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 (...)

  • armv6 : Accelerate ff_imdct_half for general case (mdct_bits != 6)

    armv6 : Accelerate ff_imdct_half for general case (mdct_bits != 6)

    The previous implementation targeted DTS Coherent Acoustics, which only
    
requires mdct_bits == 6. This relatively small size lent itself to
    
unrolling the loops a small number of times, and encoding offsets
    
calculated at assembly time within the load/store instructions of each
    
iteration.
    

    In the more general case (codecs such as AAC and AC3) much larger arrays
    
are used - mdct_bits == [8, 9, 11]. The old method does not scale for
    
these cases, so more integer registers are used with non-unrolled versions
    
of the loops (and with some stack spillage). The postrotation filter loop
    
is still unrolled by a factor of 2 to permit the double-buffering of some
    
VFP registers to facilitate overlap of neighbouring iterations.
    

    I benchmarked the result by measuring the number of gperftools samples
    
that hit anywhere in the AAC decoder (starting from aac_decode_frame())
    
or specifically in ff_imdct_half_c / ff_imdct_half_vfp, for the same
    
example AAC stream :
    

                      Before          After
    
                  Mean   StdDev   Mean   StdDev  Confidence  Change
    
aac_decode_frame  2368.1 35.8     2117.2 35.3    100.0%      +11.8%
    
ff_imdct_half_*   457.5  22.4     251.2  16.2    100.0%      +82.1%
