    12 mars 2010, par

    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

    9 février 2011, par

  • FFmpeg saving rtmp live stream cuts off after 3 minutes

    20 janvier 2013, par user1636922

    I was playing with ffmpeg and was able to save a live stream to a file. The command to do so is :

    ffmpeg -re -i "rtmp://<ip addr="addr">/livestream live=1" -f h264 test.flv
    
</ip>

    However, I have tested this twice, and both times ffmpeg stops after grabbing 3:28 worth of live video.

    The entire output is here :

    bash-4.2$ ffmpeg -re -i "rtmp://<ip addr="addr">/livestream live=1" -vcodec libx264 -f h264 test.flv

    This audio file cannot be played in some players and I think it is

    [aac @ 0x17eede0] Number of bands (64) exceeds limit (46).
    
Error while decoding stream #0.0

    What that mean and how can I avoid this ?
