  • 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 file conversion unreadable [on hold]

    16 août 2015, par rashadb

    I used ffmpeg to shorten a Videohive file from 14 seconds to 5 seconds with the following entry on the command line :

    ffmpeg -i 15_Shopping_VKV.mov -t 5 shoes.mp4

    The file doesn’t work when I try to play it with Quicktime. Along with other Google searches, I looked at the following links in Stackoverflow for suggestions :

    https://stackoverflow.com/questions/25831944/unreadable-files
    https://stackoverflow.com/questions/4818681/ffmpeg-conversion-error
    https://stackoverflow.com/questions/22307229/ffmpeg-mp4-file-is-not-valid

    At this point I’m out of ideas to figure out what’s wrong, let alone how to fix the problem.

    Here are some additional details :

    I managed to edit a few other Videohive files but each file comes in slightly different format and although I’ve converted a number of other files with a similar entry or one that adjusts the codec to something web ready, I’ve been unable to successfully convert this file. Like all of the other original videohive files it is readily read by QuickTime. Only after the conversion does this file not work. All other files I’ve converted worked with the following conversions for example :

    ffmpeg -i mainfile.mp4 -t 5:00 rave.mp4

    OR

    ffmpeg -i 00299.mov -c:v libx264 dating.mp4

    Here are a few additional details that may help :

    1) a link to the broken file
