  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Anomalie #3769 : form_hidden insère un hidden en trop

    16 avril 2016, par jluc -

    Exemple de situation où ça pose problème :

    Sur une page article, un formulaire de recherche multi critères utilise form_hidden et renvoie vers #URL_PAGEarticles (au pluriel). Cette page est polyvalente et la boucle d’affichage principal a tous les critères possibles, dont id_article ?.

    Vu que form_hidden récupère l’id_article de la page article courante, la page résultat reçoit l’id_article en critère... ce qui restreint drastiquement les résultats présentés !

  • Install openCV with ffmpeg support on OS X

    4 janvier 2017, par saulspatz

    I’m trying to install openCV with ffmpeg support on Yosemite. I had just successfully installed openCV, but video didn’t work properly, and I was advised to rebuild it with ffmpeg support. So, I installed ffmpeg with

    brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --   with-libass --with-libquvi --with-libvorbis --with-libvpx --with-opus --with-x265

    Then I used the following script to run cmake :

    PYTHON3_DIR=`python3-config --prefix` # Get python 3 path
    
VIRTUAL_ENV=`python3-config --prefix`
    
FFMPEG_INCLUDE_DIR=/usr/local/Cellar/ffmpeg/3.2.2/include/
    
FFMPEG_LIB_DIR=/usr/local/Cellar/ffmpeg/3.2.2/lib/
    
cmake -D CMAKE_BUILD_TYPE=RELEASE \
    
-D CMAKE_INSTALL_PREFIX=$VIRTUAL_ENV \
    
-D PYTHON_EXECUTABLE=$VIRTUAL_ENV/bin/python3 \
    
-D PYTHON3_PACKAGES_PATH=$VIRTUAL_ENV/lib/python3.5/site-packages \
    
-D PYTHON3_INCLUDE_DIR=$VIRTUAL_ENV/include/python3.5m \
    
-D PYTHON3_LIBRARY=$PYTHON3_DIR/lib/libpython3.5m.dylib \
    
-D PYTHON3_NUMPY_INCLUDE_DIRS=$VIRTUAL_ENV/lib/python3.5/site-packages/numpy/core/include/ \
    
-D INSTALL_C_EXAMPLES=ON \
    
-D INSTALL_PYTHON_EXAMPLES=ON \
    
-D BUILD_EXAMPLES=ON \
    
-D WITH_FFMPEG=ON \
    
-D BUILD_opencv_python3=ON \
    
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..

    This was the same script that I’d used before, with the addition of the two FFMPEG_ directories and the -D WITH_FFMPEG=ON flag. Now when I run make it fails with a bunch of errors relating to freeType.
