  • Amélioration de la version de base

    13 septembre 2013

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • avfilter/vf_idet : Fixes issue with idet not flushing last frame.

    22 octobre 2014, par Neil Birkbeck
    avfilter/vf_idet : Fixes issue with idet not flushing last frame.

    Uses a similar approach as vf_yadif to flush the last frame in idet.
    

    Quick test with 50 frames from vsynth1 :
    
./ffmpeg.old -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1  | grep Multi
    
 (gives) [Parsed_idet_0 @ 0x261ebb0] Multi frame detection : TFF:0 BFF:0 Progressive:48 Undetermined:1
    

    ./ffmpeg -i fate-suite/ffmpeg-synthetic/vsynth1/%02d.pgm -vf idet -f mp4 -y /dev/null 2>&1  | grep Multi
    
 (gives) [Parsed_idet_0 @ 0x35a0bb0] Multi frame detection : TFF:0 BFF:0 Progressive:49 Undetermined:1
    

    Fate tests have been updated.
    

    (In testing, it seems this filter will also need a subsequent patch for single frame input)

  • 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*)&amp;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.
