    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 (...)

  • Emballe médias : à quoi cela sert ?

  • ImageMagick to crop image based on based on rectangular border color

    3 septembre 2021, par Alvie Mahmud

    I have some images that I would like to crop but hopefully via command line rather than doing each one manually.

    


    I would like to crop the image (I've cropped top half, desaturated other colours and split frames with ffmpeg) based on where there is a border of a certain color (#31393C in this case). For example, I would like this image :
enter image description here
to be cropped like this :
    
enter image description here

    


    I have tried some commands but they aren't working for me unfortunately.

    


    convert image.jpg -bordercolor "#31393C" -border 2x2 -fuzz 10% -trim output.jpg


    


    I have also tried to make the parts that aren't #31393C to be filled with white and then cropping which may potentially work as a solution as I want to improve the ability to use OCR :

    


    convert image.jpg -fill white -fuzz 11% +opaque "#31393c" result.jpg
convert result.jpg -bordercolor white -border 10x10 -fuzz 10% -trim output.jpg


    


    which works somewhat but not perfectly :

  • Revision 040eeed9d0 : Turning model based reverse update on for coefs Turns model based reverse updat

    26 avril 2013, par Deb Mukherjee

    Changed Paths :
     Modify /vp9/common/vp9_entropy.c


     Modify /vp9/common/vp9_entropy.h



    Turning model based reverse update on for coefs

    Turns model based reverse updates on for coefficients in an
    effort to reduce the memory requirement for counters.

    With this patch the counters needed will be reduced by about
    75% since only 3 counts are needed instead of 12.

    The impact in performance is :
    derf300 : -0.252%
    stdhd250 : -0.046%

    However retraining should alleviate some of the drop in
    performance.

  • Zoom and Moving based on audio information in FFMPEG

    19 décembre 2019, par Mattstir

    I recently wondered if it is possible to zoom or move things in FFMPEG based on an audio source.

    I already played around with complex filters as they allow some audio visualization but didn’t really manage to move/zoom things based on sound. See good examples of complex filters used for audio visualization at : https://hhsprings.bitbucket.io/docs/programming/examples/ffmpeg/audio_visualization/index.html

    My current situation is that i have multiple inputs which one of should react on sound/maybe even on special frequency’s.
