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 (...) -
Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.
The code of this (...)

MediaMetadataRetriever setDataSource failed : status = 0xFFFFFFED
22 février 2016, par darjaI need to fetch frames from video located in the web. That’s how I do this :
class PlayerWrapper {
private static final MediaMetadataRetriever mMediaMetadataRetriever = new MediaMetadataRetriever();
…
public void initPlayback(final Context context, final VideoSurfaceView videoSurface, final String url) {
new Thread(new Runnable() {
@Override
public void run() {
…
try {
mMediaMetadataRetriever.setDataSource(url, new HashMap());
} catch (Exception e) {
DPLog(e);
}
}
}).start();
}
public Bitmap getFrameAt(int positionMillis) {
if (mMediaMetadataRetriever != null) {
DPLog.d("Creating frame for position [%s]", positionMillis);
try {
return mMediaMetadataRetriever.getFrameAtTime(positionMillis * 1000);
} catch (Exception e) {
…
return null;
}
} else {
return null;
}
}
}This works fine on several devices with Android 4.4, 5 and 6. But on one device with Android 4.1.2
setDataSourcefunction fails with following stack trace :java.lang.RuntimeException: setDataSource failed: status = 0xFFFFFFED

Why this can happen and what to do ?
I also tried to use
FFmpegMediaMetadataRetrieverwith the same logic, but it doesn’t work at all,setDataSourcecauses exceptions with status0xFFFFFFFFon all devices. As I found on SO, that means that url is invalid, but it is ok and played byMediaPlayerwithout any issues. Also I found that ffmpeg has issues with urls longer than 1024, but that’s not my case too.May be there are another way to get frames from video ?
