  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

    Often discussed but so far never working on windows with the current versions of vlc or ffmpeg.

    These are my stream’s properties :

    How to do it with vlc or ffmpeg ?

    I tried a lot. Way too much to list.

  • How to build FFMPEG lib with android ndk

    27 janvier 2017, par S. Le Galloudec

    I introduce my problem : I’m a student working on a project asked by a company to my school.
    My part is to develop an android application (i have to use c++) who can make an authentication, ask to an api wich camera the client can watch, then display in real time the stream of the IP camera (using RTSP protocol)

    To be honnest i’m pretty lost. I’ve found the library FFMPEG, wich looks like useful to my project. If i got it right, the library can display a stream from a camera. So i built the library for my project, and then i tried to include it in my program.

    I did it the same way i did to include the library curl that i already use.

    But when i try to run my program, i got this message :

    FAILURE : Build failed with an exception.
