Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa 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".

Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

FFmpeg : how to use C++ code to change the frame rate of a video file ?
27 mars 2014, par user1914692I know it would be easier to use FFmpeg commands to change the frame rate of a video file.
But anyway, if I want to do it in C++ code, and use FFmpeg libraries, how could I do it ?I think I should've be able to find out the clue in the source code.
Just before proceeding, I hope there would be some good introductions or examples. -
omxplayer - Seamless looping of a directory
18 août 2021, par delk1chI'm trying to make a script/program that will seamlessly loop through all video files in a directory using omxplayer. So far my best solution was using ffmpeg to concat the videos of the directory and loop the output using omxplayer —loop output, but I've kept running into issues with different framerates and codecs of videos and the concating itself takes way longer than I can afford. Does anyone have a clue or a snippet on how digital signage software solutions loop their videos ?

How to use palettegen and paletteuse filters with FFmpeg in C++ ?
11 janvier 2023, par Olaf JappI want to create an animated gif in a QT project.
When I scale the a QImage to AV_PIX_FMT_RGB8 directly the output looks awfull with flickering artifacts and when I scale to AV_PIX_FMT_YUV420P in between the output is dithered which does not look much better.


I found out that ffmpeg is able to produce a palette file using a filter called palettegen and then convert a movie to gif using this palette.


Is there any sample c++ file out which I could use for my project or does anybody have a clue who to use these filters in code ?
