Erstellen Sie einen videoplayer mit dem LibVLC für android

Ich versuche zu creat ein video-player für ein android-app mit dem letzten LibVLC.

Das problem ist, dass ich nicht weiß, wie die lib funktioniert und ich kann nicht finden, Probe, um mir zu helfen (wie es hier sagen https://bitbucket.org/edwardcw/libvlc-android-sample)

Also versuche ich auf meinem eigenen zu erstellen, die video-player :

public class VideoPlayerActivity extends AppCompatActivity implements IVideoPlayer, GestureDetector.OnDoubleTapListener, IDelayController {

private static LibVLC LibVLC() {
    return VLCInstance.get();
}

private static MediaPlayer MediaPlayer() {
    return VLCInstance.getMainMediaPlayer();
}

@Override
@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Toast.makeText(getApplicationContext(), "Ca start VideoPlayerActivity !!", Toast.LENGTH_SHORT).show();
    if (!VLCInstance.testCompatibleCPU(this)) {
       //exit(RESULT_CANCELED);
        return;
    }
    extras = getIntent().getExtras();
    mUri = extras.getParcelable(PLAY_EXTRA_ITEM_LOCATION);
    Toast.makeText(getApplicationContext(), "Oui ça start le VideoPlayer", Toast.LENGTH_SHORT).show();
    setContentView(R.layout.player_test);
}

@Override
public  void onResume() {
    super.onResume();

    mSurfaceView = (SurfaceView) findViewById(R.id.player_surface_test);
    setSurfaceLayout(100, 100, 100, 100, 100, 100);
    mSurfaceHolder = mSurfaceView.getHolder();
    mSurfaceFrame = (FrameLayout) findViewById(R.id.player_surface_frame_test);
    mSurfaceHolder.addCallback(mSurfaceCallback);
}

private static class ConfigureSurfaceHolder {
    private final Surface surface;
    private boolean configured;

    private ConfigureSurfaceHolder(Surface surface) {
        this.surface = surface;
    }
}

@Override
public void setSurfaceLayout(int width, int height, int visible_width, int visible_height, int sar_num, int sar_den) {

    /*if (width * height == 0)
        return;*/

    //store video size
    mVideoHeight = height;
    mVideoWidth = width;
    mVideoVisibleHeight = visible_height;
    mVideoVisibleWidth  = visible_width;
    mSarNum = sar_num;
    mSarDen = sar_den;
   Toast.makeText(this, "mVideoHeight = " + mVideoHeight, Toast.LENGTH_SHORT).show();
}

@Override
public int configureSurface(Surface surface, final int width, final int height, final int hal) {
    if (AndroidUtil.isICSOrLater() || surface == null)
        return -1;
    if (width * height == 0)
        return 0;
    Log.i(TAG, "configureSurface: " + width +"x"+height);

    final ConfigureSurfaceHolder holder = new ConfigureSurfaceHolder(surface);

    final Handler handler = new Handler(Looper.getMainLooper());
    handler.post(new Runnable() {
        @Override
        public void run() {
            if (mSurface == holder.surface && mSurfaceHolder != null) {
                if (hal != 0)
                    mSurfaceHolder.setFormat(hal);
                mSurfaceHolder.setFixedSize(width, height);
            }
            synchronized (holder) {
                holder.configured = true;
                holder.notifyAll();
            }
        }
    });
    try {
        synchronized (holder) {
            while (!holder.configured)
                holder.wait();
        }
    } catch (InterruptedException e) {
        return 0;
    }
    return 1;
}

@Override
public void eventHardwareAccelerationError() {
}

private void startVideo() {
    //LibVLC lib = new LibVLC();
    mMediaPlayer = VLCInstance.getMainMediaPlayer();
    Media media = new Media(VLCInstance.get(), mUri.getPath());
    media.parse();
    Toast.makeText(this, "le media dure : "+media.getDuration(), Toast.LENGTH_SHORT).show();
   //Toast.makeText(this, "le media dure : "+media., Toast.LENGTH_SHORT).show();
    mMediaPlayer.setMedia(media);
    //mMediaPlayer.setVideoTrackEnabled(true);
    //media.release();
   //mMediaPlayer.setEqualizer(VLCOptions.getEqualizer());
   //mMediaPlayer.setVideoTitleDisplay(MediaPlayer.Position.Disable, 0);
    int sw = getWindow().getDecorView().getWidth();
    int sh = getWindow().getDecorView().getHeight();
    VLCInstance.get().setWindowSize(sw, sh);
    mMediaPlayer.play();
    Toast.makeText(this, "le player a une valeur de : "+mMediaPlayer.isPlaying(), Toast.LENGTH_SHORT).show();
   //media.parse();
   //media.release();
   //mMediaPlayer.setMedia(media);
   //mMediaPlayer.play();
}

private final SurfaceHolder.Callback mSurfaceCallback = new SurfaceHolder.Callback() {
    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
        if(MediaPlayer() != null) {
            width = 100;
            height =100;
            Toast.makeText(getApplicationContext(), "surface width = "+width, Toast.LENGTH_SHORT).show();
            Toast.makeText(getApplicationContext(), "surface height = "+height, Toast.LENGTH_SHORT).show();
            final Surface newSurface = holder.getSurface();
            if (mSurface != newSurface) {
                mSurface = newSurface;
                Toast.makeText(getApplicationContext(), "surfaceChanged: " + mSurface, Toast.LENGTH_SHORT).show();
                LibVLC().attachSurface(mSurface, VideoPlayerActivity.this);
                mSurfaceReady = true;
                startVideo();
                //mHandler.sendEmptyMessage(1);
            }
        }
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        Log.i(TAG, "surfaceDestroyed");
        if(MediaPlayer() != null) {
            mSurface = null;
            LibVLC().detachSurface();
            mSurfaceReady = false;
        }
    }
};

private final Handler mHandler = new VideoPlayerHandler(this);

private static class VideoPlayerHandler extends WeakHandler<VideoPlayerActivity> {
    public VideoPlayerHandler(VideoPlayerActivity owner) {
        super(owner);
    }

    @Override
    public void handleMessage(Message msg) {
        VideoPlayerActivity activity = getOwner();
        if(activity == null) //WeakReference could be GC'ed early
            return;

        switch (msg.what) {
            case 1:
                activity.startVideo();
                break;
            default:
                break;
        }
    }
};

public static void start(Context context, Uri uri) {
    start(context, uri, null, false, -1);
}

public static void start(Context context, Uri uri, boolean fromStart) {
    start(context, uri, null, fromStart, -1);
}

public static void start(Context context, Uri uri, String title) {
    start(context, uri, title, false, -1);
}

private static void start(Context context, Uri uri, String title, boolean fromStart, int openedPosition) {
    Intent intent = new Intent(context, VideoPlayerActivity.class);


    intent.setAction(PLAY_FROM_VIDEOGRID);
    intent.putExtra(PLAY_EXTRA_ITEM_LOCATION, uri);
    intent.putExtra(PLAY_EXTRA_ITEM_TITLE, title);
    intent.putExtra(PLAY_EXTRA_FROM_START, fromStart);
    intent.putExtra(PLAY_EXTRA_OPENED_POSITION, openedPosition);

    /*if (openedPosition != -1)
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_MULTIPLE_TASK);*/
    Toast.makeText(context, "uri = "+uri.toString(), Toast.LENGTH_SHORT).show();
    context.startActivity(intent);  ///!\ start the activity /!\ !!!
}

@Override
public void showAudioDelaySetting() {

}

@Override
public void showSubsDelaySetting() {

}

@Override
public void endDelaySetting() {

}

@Override
public boolean onSingleTapConfirmed(MotionEvent motionEvent) {
    return false;
}

@Override
public boolean onDoubleTap(MotionEvent motionEvent) {
    return false;
}

@Override
public boolean onDoubleTapEvent(MotionEvent motionEvent) {
    return false;
}
}

Starten die videoPlayerActivity ich nenne start(Context context, Uri uri) und es wird creat die Aktivität.

Zum resum diesem code :

Nach der oncreat() ich nenne onResum() aufrufen, werden ein mSurfaceHolder.addCallback(mSurfaceCallback); und diese callback-Anruf startVideo() sollte das video zu starten, aber nichts starten..

Also, wenn jemand ein Beispiel zum erstellen einer einfachen video-player mit der letzten LibVLC oder eine Idee, wo ich scheitern, wäre es hilfreich,
