  • 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 (...)

  • 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 (...)

  • 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 (...)

  • Improve encoding speed on older Intel CPUs.

    4 décembre 2014, par Erik de Castro Lopo
    Improve encoding speed on older Intel CPUs.

    The commit http://git.xiph.org/?p=flac.git;a=commit;h=e9d805dd4374
    
changed the that calculate autocorrelation. However, the new code
    
worked slightly (about 4%) slower on Core 2, but with the new
    
presets the speed decrease can reach 25%.
    

    This patch enables both old and new functions and chooses between
    
them at runtime.

  • Revision 8fd3f9a2fb : Enable non-rd mode coding on key frame, for speed 6. For key frame at speed 6 :

    12 novembre 2014, par Marco

    Changed Paths :
     Modify /test/vp9_avg_test.cc


     Modify /vp9/common/vp9_rtcd_defs.pl


     Modify /vp9/encoder/vp9_avg.c


     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_speed_features.c


     Modify /vp9/encoder/x86/vp9_avg_intrin_sse2.c



    Enable non-rd mode coding on key frame, for speed 6.

    For key frame at speed 6 : enable the non-rd mode selection in speed setting
    and use the (non-rd) variance_based partition.

    Adjust some logic/thresholds in variance partition selection for key frame only
    (no change to delta frames),
    mainly to bias to selecting smaller prediction blocks, and also set max tx size
    of 16x16.

    Loss in key frame quality ( 0.6-0.7dB) compared to rd coding,
    but speeds up key frame encoding by at least 6x.
    Average PNSR/SSIM metrics over RTC clips go down by 1-2% for speed 6.

  • Revision 9d88b30854 : Remove redundant vp9_zero in choose_partitioning It makes the overall speed -6

    5 décembre 2014, par Jingning Han

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



    Remove redundant vp9_zero in choose_partitioning

    It makes the overall speed -6 about 2% faster with no compression
    performance change.
