  • 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.

  • 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.

  • Le profil des utilisateurs

  • Problems compiling ffmpeg on windows using cygwin

    26 mai 2014, par Papajohn000

    I’ve been having a lot of trouble recently compiling ffmpeg on windows. I’m currently using the cgywin terminal to run the code. I’ve tried following many of the most popular tutorials on the web but I can’t seem to get it to work. I’m currently using this tutorial as a guide http://www.roman10.net/how-to-build-ffmpeg-for-android/

    Where I’m at :

    I’ve created a bash script

    I then followed steps 4-6 of this post Does anyone find this useful ? - Compiling FFMPEG on Windows with Cywin and NDK r5 which consists of

    4 - Open the file 'configure' in the root of the FFMPEG directory in a text editor.

    5 - Comment out lines 2073, 2074 and 2075.

    6 - Below 2075, add the following line:

    TMPDIR=c:/cygwin/tmp

    After this script runs I get some new files within my ffmpeg folder. They are .config, config(header), config.mak , config.fate. The android folder is never created like it is supposed to. I’m also not sure where the library.mak error is coming from considering that it came with ffmpeg download.

    I’m not sure where this i’m going wrong in all of this. I feel like the fact that I’m using windows will make this build process different.

  • Issue installing OpenCV 3.0.0 on Ubuntu 14.04

    26 septembre 2015, par marcman

    I’ve been trying to install OpenCV on a Linux machine running Ubuntu 14.04. I’ve installed all of the dependencies that I have come across in tutorials as well as those listed on the OpenCV site. However, I’m pretty new to Linux and the Linux file system, so I wouldn’t be terribly surprised if these issues are related to the installation location or something.

    It appears that I am getting an issue with FFMPEG stuff, but I definitely have it installed

    dpkg -s libgtk2.0-0 | grep '^Version'

    returns

    Version: 2.24.23-0ubuntu1.3

    I’m not quite sure what the issue is here. Below is the error printout. Most of the lines are pretty much identical (I’m assuming the same issue is causing each of these errors). Although I posted the whole thing below for completeness, you can probably get at the issue from one or two of the errors as well as the last line. For brevity’s sake, here are a sample of the errors :

    ...
    /usr/opencv-3.0.0/modules/videoio/src/cap_ffmpeg_impl.hpp:738:67: error: 'PIX_FMT_RGB24' was not declared in this scope
        avpicture_fill((AVPicture*)&rgb_picture, rgb_picture.data[0], PIX_FMT_RGB24,
                                                                      ^
    /usr/opencv-3.0.0/modules/videoio/src/cap_ffmpeg_impl.hpp:756:17: error: 'PIX_FMT_BGR24' was not declared in this scope
                    PIX_FMT_BGR24,
                    ^
    ...
    [ 35%] Built target opencv_photo
    make: *** [all] Error 2
    $

    The commands immediately preceding the errors were

    $ cmake -DWITH_QT=ON -DWITH_OPENGL=ON -DFORCE_VTK=ON -DWITH_TBB=ON -DWITH_GDAL=ON -DWITH_XINE=ON -DBUILD_EXAMPLES=ON ..
    $ make -j4

    as taken from the tutorial I linked to above.
