  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • FFMPEG - How to Extract Frames As Images While Removing Sequentially Duplicate Frames

    19 mars 2017, par Michael Nelson

    Is there any way (via script or preferably some parameter in calling ffmpeg that I missed) to extract frames from an avi file and ignore sequentially duplicate frames, thus being able to go through the pictures looking only at the deltas/changes ?

    I frequently have to record meetings at work and a lot of the time, the client screen that I am looking at is not changing while we are talking over the phone. After the meeting is over, I need to use these images as part of our documentation and specifications gathering.

    I know that I could just output every frame and run them through any given duplicate file remover utility, but this would remove ALL duplicate frames. So, if the frames extracted went like this :

    A, A, A, B, B, B, B, C, C, A, A, C, C, C, B, B, B ...

    Running them through a typical duplicate file remover, I would get : A, B, C

    What I would want is : A, B, C, A, C, B

    The command that I am currently using to extract the images is :

    ffmpeg.exe -i file.avi -ss 0 -sameq -f image2 -r 1 images%5d.png

    I was getting every frame beforehand (removing the -r 1 from above), but that was generating way too many frames to deal with since these online meetings can go for hours, so for now, I get one frame per second from the file.

    A Windows based solution would be preferable, however, I’m sure other people would be interested in solutions on other platforms if available.

    Any solution or point in the right direction is much appreciated.
