Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.
La documentation de l’utilisation du script d’installation (...) -
Demande de création d’un canal
12 mars 2010, parEn fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.
Les deux manières demandent les mêmes choses fonctionnent à peu près de la même manière, le futur utilisateur doit remplir une série de champ de formulaire permettant tout d’abord aux administrateurs d’avoir des informations quant à (...) -
La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

Compiling FFmpeg : libx264 not found
17 mars 2016, par SaidTagnitI hope some one helps me the solve this problems. I was trying to compile FFmpeg 2.2.3 library under ubuntu 12.04LTS for android using android ndk r10e by following this tutorials :
here is my build_android.sh file :

If you think configure made a mistake, make sure you are using the
latest version from Git. If the latest version fails, report the
problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on
irc.freenode.net. Include the log file "config.log" produced by
configure as this will helpit seems like it can’t find where the libraries are, as i get a lot of the following errors in config.log file :

java bufferedimage array data immediately changes

}
catch (Exception e) { /*e.printStackTrace();*/ }
}//END for
return totFrames;
}//END METHOD long getFrameCount()Hope someone can explain this to me...
I am just learning java so here goes...
I wrote this code to count the number of frames in a .mov file and to test my buffered image array I generated files of the images. As the code is, it works as planned... The problem is immediately after the capturing, if I send the bufferedimages out as files, they all seem to be just the first image. see example below...for(int i = 0 ; i < frameNums ; i++)
{
try
{
frameArray[i]= grab.grab().getBufferedImage();
totFrames = i;
File outputfile = new File(fileLocation + "GrayScaledImage" + i + ".jpg");
ImageIO.write(frameArray[i], "jpg", outputfile);
}
catch (Exception e) { /*e.printStackTrace();*/ }
}//END forAnd now if I change that to...
for(int i = 0 ; i < frameNums ; i++)
{
try
{
frameArray[i]= grab.grab().getBufferedImage();
totFrames = i; catch (Exception e) { /*e.printStackTrace();*/ }}
for(int j = 0; j < frameNums; j++)
{
File outputfile = new File(fileLocation + "GrayScaledImage" + j + ".jpg");
ImageIO.write(frameArray[j], "jpg", outputfile);
}I don’t understand why I am getting the same image repeatedly.
If further information Is required, just lemme know, this is my first programming question online... Usually find what I am looking for that others have asked. Couldn’t find this one.
Thanks for your time
