Estoy tratando de crear un reproductor de video para una aplicación de Android con el último LibVLC.

El problema es que no sé cómo funciona esta lib y no puedo encontrar una muestra para ayudarme (como se dice aquíhttps://bitbucket.org/edwardcw/libvlc-android-sample)

Así que intento crear el reproductor de video por mi cuenta:

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;
}
}

Para iniciar el videoPlayerActivity llamostart(Context context, Uri uri) y creará la actividad.

Para resumir este código:

Después de laoncreat() Yo lo llamoonResum() eso llamará unmSurfaceHolder.addCallback(mSurfaceCallback); y esta llamada de devolución de llamadastartVideo() eso debería comenzar el video, pero nada comienza ...

Entonces, si alguien tiene una muestra de cómo crear un reproductor de video simple con el último LibVLC o una idea de dónde fallo, sería útil
