  • 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" (...)

    Make the intra rd search support 8x4/4x8

    This commit allows the rate-distortion optimization of intra coding
    capable of supporting 8x4 and 4x8 partition settings.

    It enables the entropy coding of intra modes in key frame using a
    unified contextual probability model conditioned on its above/left
    prediction modes.

    Coding performance :
    derf 0.464%

    Make sb intra rd search consistent with encoding

    This commit makes operations of the superblock intra coding rate
    distortion optimization consistent with those used in the encoding
    process. Given the test prediction mode and transform size, the rd
    optimizer encodes and reconstructs each transformed block of the
    superblock consecutively, then computes the total rate-distortion
    costs accosicated with the current superblock to select the coding
    decisions.

    It achieves coding performance gains :
    derf 0.353%
    yt 1.111%

  • Revision 74ded4863e : Enable conditional skip path in rd_pick_intra_sby_mode These speed-up features

    Enable conditional skip path in rd_pick_intra_sby_mode

    These speed-up features for key frame coding are only turned on
    in the settings of hybrid non-RD and RD mode decision. It provides
    about 20% speed-up to the hybrid key frame coding at the expense
    of certain compression performance loss. For vidyo1, the key frame
    coding statistics are changed
    9838F, 35.020 dB, 61677 us -> 9920F, 34.834 dB, 47556 us

    Overall rtc set compression performance is down by -0.257%.
