Changer son thème graphique
22 février 2011, parLe thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.
Le placement peut être modifié effectivement, mais cette modification n’est que visuelle et non pas au niveau de la représentation sémantique de la page.
Modifier le thème graphique utilisé
Pour modifier le thème graphique utilisé, il est nécessaire que le plugin zen-garden soit activé sur le site.

Initialisation de MediaSPIP (préconfiguration)
20 février 2010, parLors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

Download brightcove video
17 mai 2015, par desert877So I have sucessfully downloaded flash videos on in the past but for some reason I am having issues with a local news report. The video I am trying to download is :
When I check network sources I get the following output :
I downloaded a tool recommend to me call ffmpeg and ran a command from a forum that said "Invalid data found when processing input". Unable to figure out issue there.
Does any one know any scripts/code/tools/methods whatever that I can use to download this video ?
Any help would be great.

make error in OpenCV installation on ubuntu (ffmpeg CODEC_ID_XXXX was not declared in scope)
22 avril 2015, par Anurag PriyadarshiI am trying to install OpenCV following this tutorial. I am through cmake.(The configuration is given at the end.) However make shows error :
make[2]: ***[modules/highgui/CMakeFiles/opencv_highgui.dir/src/cap_ffmpeg.cpp.o] Error 1
One link pointed out reason as different version of opencv and ffmpeg, but I found a piece of code in cap_ffmpeg_impl.hpp that appears to be handling it.#if LIBAVCODEC_BUILD >= CALC_FFMPEG_VERSION(54,25,0)
# define CV_CODEC_ID AVCodecID
# define CV_CODEC(name) AV_##name
#else
# define CV_CODEC_ID CodecID
# define CV_CODEC(name) name
#endifNot sure if it is ok for this to be commented.
Also, I could try installing ffmpeg seperately, but I am not sure how dependencies are handled in this installation around libav.
Would be thankful for any help in solving this problem, as well as tips/links for OpenCV installation in general.

Installing full multimedia stack on server (ffmpeg,mp4box,sox,mplayer)
29 avril 2015, par hdezelaI’ve had a trusty text file with all(?) the steps I need to set up a full multimedia stack on a RHEL compatible server (CentOS, AWS Linux, etc.) for a few years now. However, sometimes some things are missing and I need to revise it. I know it is not complete so I’m asking for suggestions/modifications in order to get a good - and public - list of how to install all this stuff easily.
Ideally, I want to be able to run through the file and end up with a system that’ll take any media file and be able to convert/encode/decode/whatever with it.
This is what I have :
yum install mesa-libGL-devel mesa-libGLU-devel libXi-devel libXmu-devel freeglut-devel freeglut ncurses-devel
