  • 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 (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • ffmpeg problem in ubuntu (libavcodec.so)

    7 décembre 2016, par lyuba

    I run Ubuntu and try to use the ffmpeg wrapper in Java from here :
    http://code.google.com/p/javacv/

    It seems to work fine on other systems, but in Ubuntu the project crashes
    with the following mistake :
    Exception in thread "main" java.lang.UnsatisfiedLinkError : Error looking up
    function ’avcodec_decode_video2’ : /usr/lib/i686/cmov/libavcodec.so :
    undefined symbol : avcodec_decode_video2

    ffmpeg is working great from the command line, though.

    JavaCV author recommended me to check this link :
    http://linux-tipps.blogspot.com/2009/05/pretending-package-is-installed-by.html

    Probably I’m doing something wrong, but it cannot reinstall libavcodec51
    like this.

    So the questions are :
    1. Is those solution above a good one so I should bring it to success
    somehow ?
    2. What are the other ways to solve the problem ?

    Thank you for your suggestions in advance !

  • ffmpeg : Setting GOP structure, Picture structure when converting to MPEG-2 [on hold]

    27 juin 2017, par Jude

    I have a yuv file named src9_ref__625.yuv from the following website :
    ftp://vqeg.its.bldrdoc.gov/SDTV/VQEG_PhaseI/TestSequences/Reference/

    It contains 720 pixels (1440 bytes) per horizontal line and has 576 active lines per frame. Each line is in multiplexed 4:2:2 component video format as follows : Cb Y Cr Y ... 720 Y bytes per line, 360 Cb bytes per line, 360 Cr bytes per line.

    How to convert that file to MPEG-2 with following coding parameters :

    • GOP Structure : Automatic
    • Picture Structure : Alw Frame
    • Profile/Level : MP@ML

    ...as suggested in this article :
    http://iie.fing.edu.uy/publicaciones/2009/JL09/JL09.pdf

  • ffmpeg doesn't recognize Quicktime DV codec

    8 août 2017, par 3pointedit

    I have had success with excellent advice, on a Mac OSX10.5, converting a modified MXF media structure to h264 while retaining multitrack audio. But I cannot get ffmpeg to work in Windows environment.

    See this page.

    Here’s the result of latest failure-
