  • 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 (...)

  • Evolution #4445 (Nouveau) : Permettre de savoir si espace privé depuis tous les JS

    22 février 2020, par RastaPopoulos ♥

    En JS, il semble que SPIP ne fournisse rien pour savoir si on est dans l’admin ou pas. Or c’est indispensable au moins pour certains appels d’URL, savoir si on doit avoir ../ avant ou pas (par ex pour les API mais pas que).

    Le plugin Sélecteur générique fait ça en ajoutant depuis PHP une globale JS selecteur_test_espace_prive booléenne. Mais c’est pourri que chaque plugin doive faire ça. C’est SPIP qui devrait le fournir, comme test_espace_prive() en PHP quoi.

    Du coup soit faut fournir une globale du même style, mais en plus propre SPIP fournit déjà une classe "jquery.spip", du coup ça devrait être un attribut ou une méthode de cette classe.

    Par contre pour la place, à priori c’est pas dans ajaxCallback, puisque pour le faire solidement, c’est sûrement mieux que ce soit en utilisant la fonction PHP. Donc il faudrait que SPIP ajoute ça après le chargement de ajaxCallback, et qu’en PHP, ça rajoute un mini morceau de JS pour compléter jquery.spip avec un attribut qui dit où on est.

    Après dans n’importe quel JS de plugin, on ferait facilement if ($.spip.test_espace_prive()) { …

  • Ffmpeg examples run in debug mode [on hold]

    I’m not so professional in c and cpp. I want to run FFmpeg official examples but there are many errors on include files. I can’t solve them.

  • Why my ffmpeg video encode codes does not work on other computer ?

    Notes :

    


    


    callback is a function which prints error messsage and error code.

    
The error I recived is [uns::VideoWriter/Remux] Failed to write header to output file, error code: -22

    


    


    I want to know what is causing this and how to resolve it please.
