Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Initialisation de MediaSPIP (préconfiguration)
20 février 2010, parLors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.

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 ?
