    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 (...)

    9 mars 2015, par Alex Converse

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c



    Don’t waste time partitioning skip superblocks.

    Force 64x64 partitioning when a whole superblock is SEGMENT_LVL_SKIP. This
    drops encode times of screens mostly at rest by 20%.

  • converting audio from mp4 to wav and croping in the process using python

    7 mars 2019, par fastali

    I am looking for a package where I can use to convert the audio file from mp4 to wav simultaneously while also cropping the file using python.

    I have seen some posts about using ffmpeg to do the conversion but I dont seem to be able to run ffmpeg within python, and when converted to wav the files become around 10 times bigger which is kind of a storage issue.

    Does anyone have any suggestions except for pipelining it ?
