  • Mise à disposition des fichiers

    14 avril 2011, par

    Par défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.
    Cependant, il est possible et facile d’autoriser les visiteurs à avoir accès à ces documents et ce sous différentes formes.
    Tout cela se passe dans la page de configuration du squelette. Il vous faut aller dans l’espace d’administration du canal, et choisir dans la navigation (...)

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • FFMPEG - How av_read_frame work in case of a network stream ?

    4 mai 2012, par TheRock

    Hy,

    can anybody please explain me how av_read_frame works in case of a network stream (rtp) ?

    Is there an internal buffer that caches the received data, till I call av_read_frame again for the next packet ?

    The FFmpeg documentation says :
    "The returned packet is valid until the next av_read_frame() .."

    But how long the data are cached till they become invalid and how big is the latency then ?

    Cheers

  • Android AudioRecord to FFMPEG encode native AAC

    8 mars 2013, par Curtis Kiu

    I am doing video chatting in android and i would like to port ffmpeg to stream rtsp or rtmp but now i have a try in RTSP first.
    Somehow the problem now is av_write_frame or av_interleaved_write_frame is fail to work or just crash.
    Maybe...
    AudioRecord Sample format is not equals to FFMPEG setting
    Frame receive is not equals

    So code... AudioRecorder
