  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La 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 AVI to MP4 preserves sound, but not images [migrated]

    21 février 2013, par user1711384

    Working with FFmpeg at a conversion (any file to MP4 (H.264/AAC)) :

    ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null
    ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1

    With MPEG and WMV file it's working. With two different AVIs it didn't work. Logfiles from path 1 aren't generated and output 1 is empty, output 2 of course generates an error.

    After removing -profile:v baseline in both commands, the video file is successfully generated, but it's not possible to play it in JW Player (sound yes, but no image).

    This is the result of the first command :
