  • 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 (...)

  • Revision 24856b6abc : Speed feature to skip split partition based on var Adds a speed feature to disa

    3 août 2013, par Deb Mukherjee

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


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_onyx_int.h



    Speed feature to skip split partition based on var

    Adds a speed feature to disable split partition search based on a
    given threshold on the source variance. A tighter threshold derived
    from the threshold provided is used to also disable horizontal and
    vertical partitions.

    Results on derfraw300 :
    threshold = 16, psnr = -0.057%, speedup 1% (football)
    threshold = 32, psnr = -0.150%, speedup 4-5% (football)
    threshold = 64, psnr = -0.570%, speedup 10-12% (football)

    Results on stdhdraw250 :
    threshold = 32, psnr = -0.18%, speedup is somewhat more than derf
    because of a larger number of smoother blocks at higher resolution.

    Based on these results, a threshold of 32 is chosen for speed 1,
    and a threshold of 64 is chosen for speeds 2 and above.

  • Revision 44e039b4f5 : Further clean up of speed 4 Speed 4 still does not give a big gain over speed 3

     Modify /vp9/encoder/vp9_onyx_if.c



    Further clean up of speed 4

    Speed 4 still does not give a big gain over speed 3.
    This just cleans it up a little from the last patch and comments
    out features that do not seem to be giving much benefit.

  • 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.
