  • 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 (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Non-monotonous DTS in output for audio stream using ffmpeg concat

    24 mai 2015, par Apollo Marquis

    This was asked in FFMPEG - Non-Monotonous DTS on concat. But the poster simply opted for MP4Box after getting no reply. However, I would like to stick with ffmpeg which I think is quicker.

    I am concatenating files from a text file list of mp4 files that have been encoded at the same time using the same codecs so there should be no incompatibility between the files.

    I am not even sure what Non-monotonous DTS is (anyone ?) but I am worried it may produce some glitches in the concatenated files. They seem ok but there is some evidence of artefacts in the sound. Can I tweak my command line to get rid of this error, and will it speed up the concatenation process ?
    I am using Python subprocess call and the file passed into this function is the list of files. The function decorator is just a timer function for profiling.
    I have tried this with my system ffmpeg not just the static build, and it has the same problem.

    @fn_timer
    
def concat(file):
    
    proc = call(['/opt/jane_ng/jane_nodejs/ffmpeg-git-20150308-64bit-static/ffmpeg', '-f', 'concat', '-i', file, '-c', 'copy', '-y', 'testConcat.mp4'])

    When I run this, I get the following output :
