    The final video is available here, i’m able to read it from Safari on Mac OS, but it doesn’t work on iOS using AVPlayer or Safari.

    I also tried to play it using this sample code provided by Apple, however i get the following error :
    "The decoder required for this media cannot be found"

    Any help is appreciated

    edit 1

    I’ve edit the command line, and now i’m able to play the video using AVPlayer, but there is no sound...

  • Anomalie #3828 : Problème avec reverse-proxy

    16 septembre 2016, par FAb M

    EDIT : petite information complémentaire pour clarifier :

    Le but est de mutualiser un reverse-proxy pour plusieurs applications déterminer par la clé CLE (ex : http://tld.fr/CLE/ ).
    Mais au final si on a les moyens de créer un nom de domaine et un vhost ne servant que de reverse proxy sur la machine d’entrée, SPIP ne pose pas de problème. Mais c’est moyen.
