(Dés)Activation de fonctionnalités (plugins)
18 février 2011, parPour gérer l’ajout et la suppression de fonctionnalités supplémentaires (ou plugins), MediaSPIP utilise à partir de la version 0.2 SVP.
SVP permet l’activation facile de plugins depuis l’espace de configuration de MediaSPIP.
Pour y accéder, il suffit de se rendre dans l’espace de configuration puis de se rendre sur la page "Gestion des plugins".
MediaSPIP est fourni par défaut avec l’ensemble des plugins dits "compatibles", ils ont été testés et intégrés afin de fonctionner parfaitement avec chaque (...) -
Les tâches Cron régulières de la ferme
1er décembre 2010, parLa 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 (...) -
Participer à sa documentation
10 avril 2011La documentation est un des travaux les plus importants et les plus contraignants lors de la réalisation d’un outil technique.
Tout apport extérieur à ce sujet est primordial : la critique de l’existant ; la participation à la rédaction d’articles orientés : utilisateur (administrateur de MediaSPIP ou simplement producteur de contenu) ; développeur ; la création de screencasts d’explication ; la traduction de la documentation dans une nouvelle langue ;
Pour ce faire, vous pouvez vous inscrire sur (...)

Building my JAVA parameter array for FFMPEG
29 janvier 2016, par user3541092FFmpeg Version : N-63893-gc69defd Copyright (c) 2000-2014 the FFmpeg developers
built on Jul 16 2014 05:38:01 with gcc 4.6 (Debian 4.6.3-1)Machine : Amazon Linux t2.micro (free tier)
Sample File : sample_iTunes.mov
Sample File URL : https://support.apple.com/en-us/HT201549I’m trying to replicate the following FFmpeg command, using a string array and then pass this array into the Runtime.getRuntime().exec().
ffmpeg -i file:/var/local/ffmpegtest/media_input/sample_iTunes.mov -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand="mp42" -b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler="Stereo" /var/local/ffmpegtest/media_output/sample_iTunes.mp4 -y
NOTE : This works when I pass the full command, as a single string into Runtime.getRuntime().exec().
String _cmd = "ffmpeg -i %s -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand=\"mp42\" "
+ "-b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler=\"Stereo\" %s -y";
String _ffmpegCommand = String.format(_cmd, _inputFile, _outPutFile);
p = Runtime.getRuntime().exec(_ffmpegCommand);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}I started out with just a basic parameter list. As I add add each additional parameter, I re-build the JAR file and upload it to my EC2 instance to test for any errors.
The following string array works :
try
{
String[] _params = {"ffmpeg",
"-i",
String.format("%s", _inputFile),
"-pix_fmt",
"yuv420p",
"-c:v",
"libx264",
String.format("%s", _outPutFile),
"-y"};
p = Runtime.getRuntime().exec(_params);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}
catch (Exception e) {
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}However, when I continue to build the array with additional parameters, I begin to experience problems (lets add -vtag mp42) :
try
{
String[] _params = {"ffmpeg",
"-i",
String.format("%s", _inputFile),
"-pix_fmt",
"yuv420p",
"-c:v",
"libx264",
"-vtag", // <---- New
"mp42", // <--- New
String.format("%s", _outPutFile),
"-y"};
p = Runtime.getRuntime().exec(_params);
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}
catch (Exception e) {
BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));
String _line = null;
while((_line = _reader.readLine()) != null) {
lw.writeLine(_logPath + _logName, _line);
System.out.println(_line);
}
}Error Message : Could not write header for output file #0 (incorrect codec parameters ?) : Invalid data found when processing input
