  • 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 (...)

  • 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 (...)

  • issue after video rotation how fix

    2 avril 2015, par Vahagn

    I have next code for rotate video

    OpenCVFrameConverter.ToIplImage converter2 = new OpenCVFrameConverter.ToIplImage() ;

    for (int i = firstIndex; i <= lastIndex; i++) {
       long t = timestamps[i % timestamps.length] - startTime;
       if (t >= 0) {
           if (t > recorder.getTimestamp()) {
               recorder.setTimestamp(t);
           }
           Frame g = converter2.convert(rotate(converter2.convertToIplImage(images[i % images.length]),9 0));
       recorder.record(g);
       }
    }

    images[i] - Frame in JavaCV
    after in video have green lines

    UPDATE
    Convertation function

  • Convert all files at once to uncompressed .avi ffmpeg

    6 mai 2015, par Alsafi Safi

    FFmpeg

    Please help me to process each using one line of ffmpeg code to convert all files at once to uncompressed .avi files that are at a pixel dimension of 704x480. This codes is working nice, but I faced that. When I type (y). the output file is remove the past file (input _double_high) and create a new one with the same name. The code doesn’t convert all of them. I hope to convert all of them at the same time. Could you help editing this code :

    forfiles /p 264s /m *.264 /c "cmd /c ffmpeg -f h264 -i @file -vf scale=704*480 input_double_high.avi"
