Amélioration de la version de base
13 septembre 2013Jolie sélection multiple
Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...) -
Menus personnalisés
14 novembre 2010, parMediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
Menus créés à l’initialisation du site
Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...) -
Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

FFMpeg\Exception\RuntimeException Encoding failed - Laravel 4 PHP-FFMPEG
10 avril 2014, par WoogygunI'm using PHP-FFMPEG and the latest version of FFPMEG this is the same for my localhost and production server. Im encoding a .wav file(1.5 meg 44.1khz) to .mp3 128k bit rate.
On localhost it runs without issues but, on the production server it gives the following error.
FFMpeg \ Exception \ RuntimeException
Encoding failedMy binaries are located in the public folder right now for dev purposes.
My code is as follows :
Route::get('/audio', function() {
$ffmpeg = FFMpeg\FFMpeg::create([
'ffmpeg.binaries' => 'ffmpeg',
'ffprobe.binaries' => 'ffprobe',
'timeout' => 3600]);
$audio = $ffmpeg->open(public_path('track.wav'));
$format = new FFMpeg\Format\Audio\Mp3();
$format->on('progress', function ($audio, $format, $percentage) {
echo "$percentage % transcoded";
});
$format-> setAudioKiloBitrate(128);
$audio->save($format, 'track.mp3');}) ;
I can also confirm that FFMPEG is running via shell access :

NoMethodFoundException when trying to load native methods from jar file
20 février 2018, par Anuran BarmanI am trying to load ffmpeg methods in android. My requirement is that I dont want to pack the .so files within the apk.Only if the user wants then only I will download the jar file and load the ffmpeg native methods.After searching I think that loading .so files at run time is not possible.So what I did that I made the so file and created a different android application with only one class FFMPEG.java whose only duty is to call the native methods from ffmpeg library.so I made the jar file and loaded that into my main application with ClassLoader. Constructor is getting called so it means class is loaded but methods are not getting loaded though they are declared public in the jar file. I am trying to stream RTSP video with FFMPEG.Below are my jar file and main application codes.
