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.

Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Join videos command line debian [on hold]
2 avril 2014, par RomanGood evening
I'm looking for a solution for the following problem :
I have to join multiple video files (webM-format) with different settings (resolution, fps, ...) into one final file. I should also add an additional audio-track who's exactly as long as all video files together (wav-format).I've tried it with ffmpeg and concat like this :
ffmpeg -i "concat:file1.webm|file2.webm|file3.webm" -vcodec libvpx -s 1280x720 -i track.wav -acodec libfaac -ab 128k -async 10 final.webm
Result : Worked fine, but just with the first video file. All the others were ignored by ffmpeg.
Have you any other solution for this problem ?
Best Regards,

FFMPEG - Merging Videos with Transparency
4 juillet 2013, par user1829136I am trying to merge two videos together, both have transparency, using the command
ffmpeg.exe -i person2.mov -vf "[in] scale=iw/2:ih/2,fade=out:300:30:alpha=1, pad=2*iw:ih [left] ; movie=person2.mov, scale=iw/2:ih/2,fade=out:300:30:alpha=1 [right] ; [left][right] overlay=main_w/3:0,fade=out:300:30:alpha=1 [out]" -b:v 768k Output_people.mov
By doing that I get the following output :
http://i263.photobucket.com/albums/ii122/Fernando461/Untitled.png
As you can see, it was possible to get the two videos to be on top of each other. But then, when I try to merge this video (Output_people.mov) with another video, it doesn't have the same transparency. Is it possible to keep transparency in the outcome ?
Edit 1 :
This is the output I get : https://www.dropbox.com/s/gpid1pptfio31gd/ffmpeg-20130701-193206.log
And by "it doesn't have the same transparecy" I meant that the background is black instead of being transparent, so if I put one video on top of each other, the one in the back is covered by a black part of the one in the front.
Edit 2 :
Adding -vcodec qtrle to the code worked. Thanks mark4o !
