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 (...) -

FFmpeg - downmixing FLAC 6.1 to AAC 5.1
7 juillet 2014, par MartijnI can’t seem to figure out how to do this. I’ve been staring at these commands :
https://trac.ffmpeg.org/wiki/AudioChannelManipulationBut to no avail. It’s a tad above my level, sadly. Here’s the ffmpeg -i output for the video in question :

mimetype : application/x-truetype-fontAs you can see, one of the streams is a FLAC 6.1 stream. I wanted to convert that to AAC, and I know how to do that, basically like this :
ffmpeg -i "input.mkv" -codec:v copy -codec:a aac -strict -2 -b:a 320k -f matroska "output.mkv"But apparently AAC doesn’t support 6.1 audio :
...

Metadata:

Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #0:1 -> #0:1 (flac (native) -> aac (aac))
Stream #0:9 -> #0:2 (ssa (native) -> ssa (native))
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or heightThat’s fine, so I wanted to downmix it to 5.1 and encode as AAC. But I can’t seem to work out how to. Any advice ?

Catch if the Java proccess crashed
17 janvier 2012, par VSheyanovI run java process to convert video using ffmpeg.exe.
Runtime rt = Runtime.getRuntime();
String cmd = FFMPEGFULLPATH + " -y -i " + '"' + mpeg4File + '"' + " -vcodec libx264 -vsync 2 " + '"' + H264file + '"';
Process pr = rt.exec(cmd);
ThreadedTranscoderIO errorHandler = new ThreadedTranscoderIO(pr.getErrorStream(), "Error Stream");
errorHandler.start();
ThreadedTranscoderIO inputHandler = new ThreadedTranscoderIO(pr.getInputStream(), "Output Stream");
inputHandler.start();
try {
pr.waitFor();
} catch (InterruptedException e) {
LiveApplication.logger.info("Some shit happens during convertation 2 ");
throw new IOException("UseTranscoderBlocking - Run_FFMPEG - process interrupted " + e);
}But when the process started, sometimes especially with big files, but not always i get this windows message :
This happens only on Windows server 2008 and didn't happened on Windows 7.
I have 2 questions :
- Why this process fails ?
- Can I catch this fail in Java, close
this window and continue thread execution (maybe I'll restart this
proccess).
Thanks !
