  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • MediaMetadataRetriever setDataSource failed : status = 0xFFFFFFED

    10 octobre 2019, par darja

    I need to fetch frames from video located in the web. That’s how I do this :

    class PlayerWrapper {
    
    private static final MediaMetadataRetriever mMediaMetadataRetriever = new MediaMetadataRetriever();
    

    
    …
    

    
    public void initPlayback(final Context context, final VideoSurfaceView videoSurface, final String url) {
    
        new Thread(new Runnable() {
    
            @Override
    
            public void run() {
    
                …
    

    
                try {
    
                    mMediaMetadataRetriever.setDataSource(url, new HashMap());
    
                } catch (Exception e) {
    
                    DPLog(e);
    
                }
    

    
            }
    
        }).start();
    
    }
    

    
    public Bitmap getFrameAt(int positionMillis) {
    
        if (mMediaMetadataRetriever != null) {
    
            DPLog.d("Creating frame for position [%s]", positionMillis);
    
            try {
    
                return mMediaMetadataRetriever.getFrameAtTime(positionMillis * 1000);
    
            } catch (Exception e) {
    
                …
    
                return null;
    
            }
    
        } else {
    
            return null;
    
        }
    
    }
    
}

    This works fine on several devices with Android 4.4, 5 and 6. But on one device with Android 4.1.2 setDataSource function fails with following stack trace :

    java.lang.RuntimeException: setDataSource failed: status = 0xFFFFFFED
    
       at android.media.MediaMetadataRetriever._setDataSource(MediaMetadataRetriever.java)
    
       at android.media.MediaMetadataRetriever.setDataSource(MediaMetadataRetriever.java:99)
    
       at co.unreel.videoapp.playback.UnreelPlayer$3.run(UnreelPlayer.java:138)
    
       at java.lang.Thread.run(Thread.java:856)

    Also tried this code on emulator, got almost the same but with status 0x80000000

    Why this can happen and what to do ?

    I also tried to use FFmpegMediaMetadataRetriever with the same logic, but it doesn’t work at all, setDataSource causes exceptions with status 0xFFFFFFFF on all devices. As I found on SO, that means that url is invalid, but it is ok and played by MediaPlayer without any issues. Also I found that ffmpeg has issues with urls longer than 1024, but that’s not my case too.

    May be there are another way to get frames from video ?

    libavfilter/vf_dnn_detect : Add yolo support

    Add yolo support. Yolo model doesn't output final result. It outputs
    
candidate boxes, so we need post-process to remove overlap boxes to
    
get final results. Also, the box's coordinators relate to cell and
    
anchors, so we need these information to calculate boxes as well.
    

    Model detail please refer to : https://github.com/openvinotoolkit/open_model_zoo/tree/master/models/public/yolo-v2-tf
