  • MediaSPIP Core : La Configuration

    9 novembre 2010, par

    MediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes ; une page spécifique à la configuration de la page d’accueil du site ; une page spécifique à la configuration des secteurs ;
    Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...)

  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • FFMPEG unwanted rotation

    5 mars 2015, par Ben

    When I add a watermark image with a landscape orientation to a video that has a portrait orientation the video automatically rotates to landscape. How do I prevent this ? Also, the audio file isn’t being merged into the output. How can I include the audio.mp3 to be the sole audio track ?

    The final lib was created successfully, no error message in log file,
but when I import the lib to my Xcode Project,
the linker give me tons of errors(missing symbols like : Undefined symbol: _pjsua_vid_codec_set_priority).
I found the pjsua_vid.o is very small(200Bytes) compare to my pjsip+openh264 build file(was 47KB), perhaps this is the reason cause the link error.

    


    Here is my build log :

  • Cannot use Mobile FFmpeg and LibVLCSharp together in Xamarin.Forms project

    26 février 2021, par Travis P

    I am adding video stream capture functionality to a Xamarin Forms project. I am trying to use VLC's LibVLCSharp.Forms (https://github.com/videolan/libvlcsharp) package and the Mobile ffmpeg Xamarin wrapper package, Laerdal.Xamarin.FFmpeg.* (https://github.com/Laerdal/Laerdal.Xamarin.FFmpeg.iOS). However, the internal ffmpeg library from VLC is conflicting with the ffmpeg wrapper and is built with different flags which exclude functionality that I need.

    &#xA;

    For native development, it looks like you can configure a preferred library with the OTHER_LDFLAGS flag in the Pods-<your app="app">.debug.xcconfig</your> file but I don't see where to do that with Xamarin.Forms.&#xA;Source : https://github.com/tanersener/mobile-ffmpeg/wiki/Using-Multiple-FFmpeg-Implementations-In-The-Same-iOS-Application

    &#xA;

    How can I configure Xamarin iOS builds to prefer the mobile ffmpeg library over the VLC ffmpeg library ? If I am able to use the mobile ffmpeg library, will it cause issues with VLC ?

    &#xA;

    Here is a log message when I try to run commands with ffmpeg. As you can see, ffmpeg's internal library paths reference "vlc" :
