  • 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" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Revision 1092140379 : No longer use use_lastframe_partitioning speed feature The speedup in rd_pick_p

    6 septembre 2014, par Yunqing Wang

    Changed Paths :
     Modify /vp9/encoder/vp9_speed_features.c



    No longer use use_lastframe_partitioning speed feature

    The speedup in rd_pick_partition() function makes it possible
    to drop use_lastframe_partitioning feature. By doing that, we
    achieve good PSNR gain with small speed loss. Also, this makes
    encoding loop less complicated. The code cleanup patch will
    follow.

    Borg tests showed :
    1. At speed 2,
    stdhd set : 0.201% PSNR gain, 0.133% SSIM gain ;
    derf set : 0.262% PSNR gain, 0.276% SSIM gain.
    2. At speed 3,
    stdhd set : 0.139% PSNR gain, 0.109% SSIM gain ;
    derf set : 0.447% PSNR gain, 0.442% SSIM gain.

    The average speed loss over selected test clips is within 1%
    with the worst case of 4%.

  • Artifacts in WMP after speed-up and fps change

    11 septembre 2014, par Snow

    Trying to convert a 1 hour video with 0.02 fps, to a very short one (100 times speed-up) with somethinglike 10 fps to include in a powerpoint presentation.

    I did this :

    ffmpeg - input.mp4 -filter:v "setpts=0.01*PTS" -r 10 output.mp4

    Works great, play nicely with VLC or SMPlayer (which I believe use ffmpeg libraries for decoding). But if played with Windows Media Player, or inserted in a powerpoint presentation, this gives a lot of artifacts...the video is almost not watchable.

    Is there a way to make this watchable in powerpoint (i’m guessing the problem lies down with the video renderer used in powerpoint...)
