  • Création définitive du canal

    12 mars 2010, par

    Lorsque votre demande est validée, vous pouvez alors procéder à la création proprement dite du canal. Chaque canal est un site à part entière placé sous votre responsabilité. Les administrateurs de la plateforme n’y ont aucun accès.
    A la validation, vous recevez un email vous invitant donc à créer votre canal.
    Pour ce faire il vous suffit de vous rendre à son adresse, dans notre exemple "http://votre_sous_domaine.mediaspip.net".

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Taille des images et des logos définissables

    Dans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.

    25 août 2012, par Darius

    I ran this command

  • no c compiler found libx264 build [closed]

    24 août 2012, par kerim yucel

    I have been trying to build ffmpeg for Android and I have managed to do so by using roman10's tutorial.

    However, I needed x264 and I enabled libx264 in the configurations but it wasn't able to find the library. A quick internet search led me to the answer that I have to build x264 seperately and include it to ffmpeg config by editing ExternalLibs flags.

    Currently I am using this script to build x264. Everything is fine except the fact that the error saying "No working C compiler is found" pops up. I have updated and installed build-essential and my gcc version is up to date.

    Any help will be appreciated. Thanks a lot.

    P.S. I am using ndk 4 just to make everything compatible with the tutorial link given above. I am running Ubuntu with VirtualBox from Windows 7.

    Edit : I have been trying this tutorial as well, I am getting the same error along with unknown options error for each configuration options.

    Another edit :
    I have tried this code and obtained the following.

    echo 'int main() return 0 ;' > main.c && arm-eabi-gcc main.c || echo $ ?

    /home/mehmet/Android_NDK_r4/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/../lib/gcc/arm-eabi/4.4.0/../../../../arm-eabi/bin/ld : crt0.o : No such file : No such file or directory collect2 : ld returned

    I have checked the flags as well, flags seem ok or I can't see the faulty line. Above you may find the build script I am using.

  • Retrieving information from ffmpeg shell_exec command

At least one output file must be specified

    i want to get the information to insert into a database album,artist,genre,title etc

    But all seperately

    i can get them by doing the following

    $output = shell_exec(&#39;/usr/local/bin/ffmpeg -i intro.mp3 2>&amp;1&#39;); 
    

    
$edit = explode(&#39;  &#39;, $output);
    
$edit = implode("@", $edit);
    
$edit = explode(&#39;:&#39;, $output);
    
echo "<pre>";
    
print_r($edit);
    
echo "</pre>";

    then running

    &lt;?php echo $edit[9]; ?>

    etc

    but this seems like a really bad way and annoying way to get values and sometimes the output is slightly different which messes with the outputs.

    Whats the best way to do this or am i stuck doing this ?
