  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • Revision 4f660cc018 : Modified mode skip functionality. A previous speed feature skipped modes not us

    5 septembre 2013, par Paul Wilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c

     Modify /vp9/encoder/vp9_rdopt.c



    Modified mode skip functionality.

    A previous speed feature skipped modes not used in earlier
    partitions but this not longer worked as intended following
    changes to the partition coding order and in conjunction
    with some other speed features (Especially speed 2 and above).

    This modified mode skip feature sets a mask after the first X
    modes have been tested in each partition depending on the
    reference frame of the current best case.

    This patch also makes some changes to the order modes are
    tested to fit better with this skip functionality.

    Initial testing suggests speed and rd hit count improvements
    of up to 20% at speed 1. Quality results. (derf -1.9%, std hd +0.23%).

  • Revision e02dc84c1a : Adds a speed feature for fast 1-loop forw updates Incorporates a speed feature

    28 août 2013, par Deb Mukherjee

    Changed Paths :
     Modify /vp9/encoder/vp9_bitstream.c


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_onyx_int.h



    Adds a speed feature for fast 1-loop forw updates

    Incorporates a speed feature for fast forward updates of
    coefficients. This feature takes 3 values :
    0 - use standard 2-loop version
    1 - use a 1-loop version
    2 - use a 1-loop version with reduced updates

    Results : derfraw300 +0.007% (on speed 0) at feature value = 1
    -0.160% (on speed 0) at feature value = 2

    There is substantial speed up at speeds 2 and above for low
    resolution sequences where the entropy updates are a big part
    of the overall computations.
