Diogene : création de masques spécifiques de formulaires d’édition de contenus
26 octobre 2010, parDiogene est un des plugins ? SPIP activé par défaut (extension) lors de l’initialisation de MediaSPIP.
A quoi sert ce plugin
Création de masques de formulaires
Le plugin Diogène permet de créer des masques de formulaires spécifiques par secteur sur les trois objets spécifiques SPIP que sont : les articles ; les rubriques ; les sites
Il permet ainsi de définir en fonction d’un secteur particulier, un masque de formulaire par objet, ajoutant ou enlevant ainsi des champs afin de rendre le formulaire (...) -
MediaSPIP version 0.1 Beta
16 avril 2011, parMediaSPIP 0.1 beta est la première version de MediaSPIP décrétée comme "utilisable".
Le fichier zip ici présent contient uniquement les sources de MediaSPIP en version standalone.
Pour avoir une installation fonctionnelle, il est nécessaire d’installer manuellement l’ensemble des dépendances logicielles sur le serveur.
Si vous souhaitez utiliser cette archive pour une installation en mode ferme, il vous faudra également procéder à d’autres modifications (...) -

Get total time/progress from multiple FFmpeg terminal commands
24 septembre 2018, par katarotyI have a class that executes multiple
FFmpegcommands inAndroid. The problem is that I have no idea how to get total time and then update the progress as the commands run.Since there are so many I am not even sure if it is possible.
So hence my question : Is it possible to get total time/progress or at least estimated time/progress and then update it onProgress.
And here is my class :
public class AudioProcessor {
private Context context;
private FFmpeg ffmpeg;
private AudioProcessorListener listener;
private File micPcmFile;
private File backgroundMp3File;
private File pcmtowavTempFile;

}
public interface AudioProcessorListener {
void onStart();
void onSuccess(File output);
void onError(String message);
void onFinish();
}
}Since the whole thing is taking a long time, if someone can recommend something that would take less time, then it would also help. A 2 minute video usually takes like 50s.
