  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • 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.

  • How to convert any type of video in mp4

    23 décembre 2016, par Ankit Aneja

    I’m using meteor with blaze for development of web-app. I have used html 5 video tag for play video in browser. other types like mp4 and m4v is working fine in all browser but MOV format file is not play in any browser.

  • 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.

    • What went wrong :

    Hope i was clear
