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 (...) -
Taille des images et des logos définissables

ffmpeg not giving correct duration of a mp4
1er juin 2012, par oachI am working with ffmpeg to convert videos into flv files via php. The tests I have done do not work for mp4 conversions. I have a 13 second video (videos will be limited to 15 seconds), when it is uploaded and I check the "duration" of the video it comes out over 300 seconds. I have tried changing around how I process the video :
// original
exec('ffmpeg -i <path>/<filename> 2>&1', $output);
// current
exec('ffmpeg -i <path>/<filename> 2>&1 | grep "Duration" | cut -d \' \' -f 4 | sed s/,//', $output);
</filename></path></filename></path>The original method did not work for mpg files but the second does, but neither gives me the "correct" duration of a mp4 video. Is there a "special" way to process mp4 files ?
Thank you for your time and help.
Update :
Command line
ffmpeg -i ./custom_scraping.mp4 2>&1 | grep "Duration" | cut -d ' ' -f 4 | sed s/,//
00:05:15.84Complete output (formatted as best I could)
ffmpeg -i ./custom_scraping.mp4 2>&1
