  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Revision 8d3d2b76f3 : Tx size selection enhancements (1) Refines the modeling function and uses that

    22 juin 2013, par Deb Mukherjee

    Changed Paths :
     Modify /vp9/common/vp9_blockd.h


     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_onyx_int.h


     Modify /vp9/encoder/vp9_rdopt.c



    Tx size selection enhancements

    (1) Refines the modeling function and uses that to add some speed
    features. Specifically, intead of using a flag use_largest_txfm as
    a speed feature, an enum tx_size_search_method is used, of which
    two of the types are USE_FULL_RD and USE_LARGESTALL. Two other
    new types are added :
    USE_LARGESTINTRA (use largest only for intra)
    USE_LARGESTINTRA_MODELINTER (use largest for intra, and model for
    inter)

    (2) Another change is that the framework for deciding transform type
    is simplified to use a heuristic count based method rather than
    an rd based method using txfm_cache. In practice the new method
    is found to work just as well - with derf only -0.01 down.
    The new method is more compatible with the new framework where
    certain rd costs are based on full rd and certain others are
    based on modeled rd or are not computed. In this patch the existing
    rd based method is still kept for use in the USE_FULL_RD mode.
    In the other modes, the count based method is used.
    However the recommendation is to remove it eventually since the
    benefit is limited, and will remove a lot of complications in
    the code

    (3) Finally a bug is fixed with the existing use_largest_txfm speed feature
    that causes mismatches when the lossless mode and 4x4 WH transform is
    forced.

    Results on derf :
    USE_FULL_RD : +0.03% (due to change in the tables), 0% encode time reduction
    USE_LARGESTINTRA : -0.21%, 15% encode time reduction (this one is a
    pretty good compromise)
    USE_LARGESTINTRA_MODELINTER : -0.98%, 22% encode time reduction
    (currently the benefit of modeling is limited for txfm size selection,
    but keeping this enum as a placeholder) .
    USE_LARGESTALL : -1.05%, 27% encode-time reduction (same as existing
    use_largest_txfm speed feature).

  • Images to video in PHP ? [duplicate]

    24 juin 2013, par jesper

    This question already has an answer here :

    I have tried to make a images to video converter, and this works.

    ffmpeg  -i /home/psafari/public_html/common/images/icon3.png -vcodec mpeg4 /home/psafari/public_html/" . time().".avi

    But how can i set the duration of the movie ? So it's maybe 7 minutes long ?

    Another question :

    I have 2 pictures, now the command only make the video from image "icon3.png", but i need it to run maybe picture2.png the first 5 seconds, and the rest (6.55 seconds) it has to view icon3.png ex.
