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 (...) -
Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Java Xuggler Metadata List of Chapters MP4/M4V Video
27 juin 2017, par MrSaxI’m trying to use Xuggler like FFMPEG Metadata Wrapper (I just need the list of Chapters of MP4/M4V Video).
So far I have not been able to find a solution.
Can anyone help me ?I was only able to get the following information :
final String filename = "...path...";
IContainer container = IContainer.make();
int result = container.open(filename, IContainer.Type.READ, null);
if (result < 0)
throw new RuntimeException("Failed to open media file");
int numStreams = container.getNumStreams();
long duration = container.getDuration();
long fileSize = container.getFileSize();
long bitRate = container.getBitRate();
System.out.println("Number of streams: " + numStreams);
System.out.println("Duration (ms): " + duration);
System.out.println("File Size (bytes): " + fileSize);
System.out.println("Bit Rate: " + bitRate);
for (int i = 0; i < numStreams; i++) {
IStream stream = container.getStream(i);
IStreamCoder coder = stream.getStreamCoder();
System.out.println("*** Start of Stream Info ***");
System.out.printf("stream %d: ", i);
System.out.printf("type: %s; ", coder.getCodecType());
System.out.printf("codec: %s; ", coder.getCodecID());
System.out.printf("duration: %s; ", stream.getDuration());
System.out.printf("start time: %s; ", container.getStartTime());
System.out.printf("timebase: %d/%d; ", stream.getTimeBase().getNumerator(),
stream.getTimeBase().getDenominator());
System.out.printf("coder tb: %d/%d; ", coder.getTimeBase().getNumerator(),
coder.getTimeBase().getDenominator());
System.out.println();
if (coder.getCodecType() == ICodec.Type.CODEC_TYPE_AUDIO) {
System.out.printf("sample rate: %d; ", coder.getSampleRate());
System.out.printf("channels: %d; ", coder.getChannels());
System.out.printf("format: %s", coder.getSampleFormat());
} else if (coder.getCodecType() == ICodec.Type.CODEC_TYPE_VIDEO) {
System.out.printf("width: %d; ", coder.getWidth());
System.out.printf("height: %d; ", coder.getHeight());
System.out.printf("format: %s; ", coder.getPixelType());
System.out.printf("frame-rate: %5.2f; ", coder.getFrameRate().getDouble());
}
System.out.println();
System.out.println("*** End of Stream Info ***");UPDATE 07.06.2017

Android ffmpeg. Linker command failed with exit code 1
8 juin 2017, par Wilsom SandersI’m trying to build ffmpeg static libraries and link them to an android project in order to implement a video player. Goal is to make a player capable of receiving video file from various sources similar to p2p file sharing networks. (target api is 21 level which is 1 level short from supposed official solution with MediaSource)
I managed to compile ffmpeg from this repo (all the code used as-is) but later i got stuck on a linking problem. Whenever I try to compile I get list of ffmpeg methods called in my code and a short eloquent message :
Linker command failed with exit code 1
I have no clue how to pass -v flag to the linker in android studio. Would be great if somebody hinted me that.
I use android studio, build with gradle and cmake.
There’s my files :
