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".

Making Image Slideshows from Linux Graphic Tools [on hold]
24 octobre 2019, par VolomikeHow do I make image slideshows as a video file via 4 small jpegs (128px x 128px) and Linux command-line graphic tools ? I need to vary the slideshow transitions with :
- fade to/from black
- slide left/right while fading to next image
If you’re curious, we plan to make videos we can put into mobile phones for real estate listings. (We already have the technology to convert Ogg Theora into proprietary mobile formats.)

Getting small file size from ffmpeg [duplicate]
20 février 2020, par sukachI am not an ffmpeg expert. I am trying to get some movies converted to a smaller DIVX file for a cheap portable DVD player for a family trip. The movies are for my kids so I’m not too concerned about quality.
The DVD player is a 10.1", 1024x600 screen. It says it supports DIVX/MPEG2 files. It took me a lot of experimentation to get the right ffmpeg settings to even get it to work, but I found another answer that provided a very complex set of parameters that ultimately worked.
I have converted about 20 movies with this setting and every one results in a file size of 1.1GB. I have tried different file sizes and crf settings and it is the same every time.
Here is an example. First, the original file :

Encapsulate onvif metadata into avframe
15 avril 2020, par user8957959I have a onvif camera that provides video and metadata via rtsp. I would 
like to create a filter or whatever else that takes the metadata, reads 
them and finally merge into the output video.



I think of something like 
encapsulate them in the alpha channel, in order to keep the video 
viable. I have problem with the first part, because I cannot find a 
filter that manipulates Data (AVMEDIA_TYPE_DATA) to start with. My plan 
is to create a filter that takes data and produce fake avframe with 
metadata, that will be merged with the real video by a filter like 
overlay or everything else. Did someone have some hints for me ?
