  • 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.

  • 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 (...)

  • pthread : Avoid spurious wakeups

    18 octobre 2013, par Ben Jackson
    pthread : Avoid spurious wakeups

    pthread_wait_cond can wake up unexpectedly (Wikipedia : Spurious_wakeup).
    

    The FF_THREAD_SLICE thread mechanism could spontaneously execute
    
jobs or allow the caller of avctx->execute to return before all
    
jobs were complete.
    

    Test both cases to ensure the wakeup is real.

  • ffmpeg android unable to build

    2 janvier 2014, par nmxprime

    My goal is to build ffmpeg static libraries so that i can use them with jni and call directly the functions defined in ffmpeg to encode series of images as h264 video stream and render it on screen using GLSurfaceVIew in android 2.3.6.

    Using https://www.ffmpeg.org/doxygen/0.6/api-example_8c-source.html i came to know that by having the required .so files and headers i can do that.

    I followed Android NDK & FFMPEG build and many others. Everywhere i found reference to the build scripts by roman10.

    I use Ubunthu 12.0.4 LTS with android-ndk-r9 and ffmpeg-0.10 source !

  • problems for building FFMPEG library for android on windows
