Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...) -

Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

FFprobe Throws JsonSyntaxException with NumberFormatException on Some Video Files [closed]
3 avril, par Daydreamer067I'm using FFprobe through the Java wrapper to analyze video files :


FFprobe ffprobe = new FFprobe("pathTo/ffprobe.exe");
 FFmpegProbeResult probeResult = ffprobe.probe(fichierTemp.getPath());



This works fine for most files. However, on some video files, I get the following error :


com.google.gson.JsonSyntaxException: java.lang.NumberFormatException: Expected an int but was 109893054318340751 at line 160 column 37 path $.chapters[0].id



It seems like FFprobe is returning a chapter ID that is a long but it expected an int. How can I handle this situation and avoid this exception ?


Is there a way to customize the JSON parsing or configure FFprobe to return int values ?

FFMPEG not working as intended in a bash script
9 mai 2024, par rcpI'm trying to get the mean volume of a recording and the echo the expected value. When I do it line by line, everything works fine, but as soon as I execute it in a bash script, I have a problem with the FFMPEG line. I identified the problem, which is that
&> analysis
is not doing anything for some reason and instead of saving the output in a file it prints it in the shell.

I don't know how to fix it since it works fine when not in a script.


#!/bin/bash

# Record sound
sh aud2.sh

# Run ff.sh in the background to analyze volume and save results
ffmpeg -i test.wav -af "volumedetect" -vn -sn -dn -f null - &> analysis.vol

# Extract mean_volume and save to mean.vol
grep "mean_volume" analysis.vol > mean.vol

# Extract numerical value and save to val.vol
sed -n 's/^.*mean_volume: \([-0-9.]*\) dB.*/\1/p' < mean.vol > val.vol

# Read the value from val.vol into the variable volume
volume=$(code>


Expected output when line by line




I expected the shell output to be saved in a file.
