  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

    It seems that it was unable to find openjpeg.h and searched in folder openjpeg-2.0 to openjpeg-2.3. However, when I checked /mxe/usr/i686-w64-mingw32.static/include/, it contains openjpeg-2.4.

    


    The log for /mxe/log/gdal_i686-w64-mingw32.static is present here.

    


    Please help fix this. Thanks.

    


  • Compliing OpenCV with FFMPEG failing

    20 mai 2016, par moorej

    I’m trying to install OpenCV 3.1.0 on Ubuntu 14.04 with ffmpeg and python 2.7 support. I’m able to compile with :

    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local 
    
-D  INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=ON 
    
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.1.0/modules 
    
-D WITH_FFMPEG=OFF -D BUILD_EXAMPLES=ON ..

    But -D WITH_FFMPEG=ON fails with the error :

    /usr/bin/ld: /usr/local/lib/libavcodec.a(avpacket.o): 
    
relocation R_X86_64_32 against `.rodata.str1.1' can not be used when
    
making a shared object; recompile with -fPIC
    
/usr/local/lib/libavcodec.a: error adding symbols: Bad value
    
collect2: error: ld returned 1 exit status

    I’m compiling ffmpeg as well and I’ve looked at a number of posts relating to the problem and attempted to add —enable-pic and —enable-shared along with some other options but I have to admit I’m a bit stupid when it comes to anything compilation related. My process for compiling ffmpeg is below. Please help me with my mess. Thanks !
