  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • Soumettre améliorations et plugins supplémentaires

    10 avril 2011

    Si vous avez développé une nouvelle extension permettant d’ajouter une ou plusieurs fonctionnalités utiles à MediaSPIP, faites le nous savoir et son intégration dans la distribution officielle sera envisagée.
    Vous pouvez utiliser la liste de discussion de développement afin de le faire savoir ou demander de l’aide quant à la réalisation de ce plugin. MediaSPIP étant basé sur SPIP, il est également possible d’utiliser le liste de discussion SPIP-zone de SPIP pour (...)

  • Librairies et logiciels spécifiques aux médias

    10 décembre 2010, par

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.
    Il est important, après avoir installé apache2, mysql et php5, d’installer d’autres logiciels nécessaires dont les installations sont décrites dans les liens afférants. Un ensemble de librairies multimedias (x264, libtheora, libvpx) utilisées pour l’encodage et le décodage des vidéos et sons afin de supporter le plus grand nombre de fichiers possibles.

  • Android FFMPEG java concat multiple files

    17 juillet 2015, par Kim T

    I’m using a fork of the cordova-plugin-video-editor library :

    https://github.com/jbavari/cordova-plugin-video-editor/pull/13

    Which uses the android-ffmpeg-java library here :

    https://github.com/guardianproject/android-ffmpeg-java

    The out of box cordova plugin example works well to encode a single video using the following code :

    File tempFile = File.createTempFile("ffmpeg", null, appContext.getCacheDir());
    
FfmpegController ffmpegController = new FfmpegController(appContext, tempFile);
    

    
TranscodeCallback tcCallback = new TranscodeCallback();
    

    
Clip clipIn = new Clip(videoSrcPath);
    
Clip clipOut = new Clip(outputFilePath);
    
clipOut.videoCodec = "libx264";
    
clipOut.videoFps = "24"; // tailor this to your needs
    
clipOut.videoBitrate = 512; // 512 kbps - tailor this to your needs
    
clipOut.audioChannels = 1;
    
clipOut.width = outputWidth;
    
clipOut.height = outputHeight;
    
clipOut.duration = videoDuration;
    
ffmpegController.processVideo(clipIn, clipOut, true, tcCallback);

    This calls the android-ffmpeg-java code here :

    https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/FfmpegController.java#L225

    They have a multiple file concat test example here :

    https://github.com/guardianproject/android-ffmpeg-java/blob/master/src/org/ffmpeg/android/test/ConcatTest.java#L16

    So I have modified the cordova plugin code to match the example :

    ArrayList<clip> listVideos = new ArrayList<clip>();
    

    
Clip clip = new Clip();
    
clip.path = new File(videoSrcPath).getCanonicalPath();
    
ffmpegController.getInfo(clip);
    
clip.duration = 5;
    
listVideos.add(clip);
    

    
Clip clip2 = new Clip();
    
clip2.path = new File(videoSrcPath2).getCanonicalPath();
    
ffmpegController.getInfo(clip2);
    
clip2.duration = 5;
    
listVideos.add(clip2);
    

    
Clip clipOut = new Clip();
    
clipOut.path = new File(outputFilePath).getCanonicalPath();
    
ffmpegController.concatAndTrimFilesMP4Stream(listVideos, clipOut, false, false, new ShellUtils.ShellCallback() {
    
    @Override
    
    public void shellOut(String shellLine) {
    
        System.out.println("fc>" + shellLine);
    
    }
    
    @Override
    
    public void processComplete(int exitValue) {
    
        if (exitValue &lt; 0)
    
            System.err.println("concat non-zero exit: " + exitValue);
    
    }
    
});
    
</clip></clip>

    However when run I get the error :

  • vcodec copy does not work when start/duration is messed up in video file

    25 janvier 2014, par anishsane

    My Video file shows below meta-data with ffprobe/ffmpeg :

    Duration: 00:44:27.52, start: 1333.760000, bitrate: 335 kb/s
    
  Stream #0.0(und): Video: h264 (Main), yuv420p, 640x480, 25 tbr, 90k tbn, 50 tbc

    Note : The file does not contain audio.

    I am trying to convert this video file to other video file, using ffmpeg/avconv.

    This works : (but encodes h.264 video to mpeg4)

    ffmpeg -i input.mp4 output.mp4

    & it generates output file of proper duration (44:27 - 1333 seconds = 22:14)

    This does not work :

    ffmpeg -i input.mp4 -vcodec copy output.mp4

    Generates file without video.

    The output contains :

    $ avconv -i input.mp4 -vcodec copy output.mp4

  • Running an Terminal command inside a Directory

    22 janvier 2014, par user3220153

    I want to run and tell ffmpeg, a video converter, to combine an audio and video file to one video file. I want to do this in terminal so I can do this repeatedly and quickly.

    This works in Terminal :

    [directoryX]/ ffmpeg -i [directoryX]/sound.wav -i [directoryX]/movie.avi video_finale.mpg
    Pause

    But I do NOT want to keep specifying the directory in Terminal because there are many folders in which I need to do this. I would like to create a .command file, copy it and the ffmpeg application (very small), and past it in every folder that needs a video conversion. I would then run the .command file and it would execute the command mentioned above in the local folder. What is the best way to approach this ???

    This line in .command file does NOT work (inside the folder with ffmpeg, audio and video) :

    ffmpeg -i sound.wav -i movie.avi video_finale.mpg
    Pause

    I get :

    wireless-10-146-122-30:~ yagostucky$ /Volumes/TURBOLINEA/inFrontOfMe/footage/jan-19-2014/dollGhost_duke_act1_scene3_take1/batch.command ; exit;
