Créer un videoplayer avec la LibVLC pour android

Je suis en train de créer un lecteur vidéo pour une application android avec la dernière LibVLC.

Le problème est que je ne sais pas comment cette lib fonctionne et je ne peux pas trouver un exemple pour m'aider (comme il est dit ici https://bitbucket.org/edwardcw/libvlc-android-sample)

J'ai donc essayer sur mon propre pour créer le lecteur vidéo :

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;
}
}

Pour démarrer le videoPlayerActivity j'appelle start(Context context, Uri uri) et il va créer de l'activité.

À resum ce code :

Après la oncreat() j'appelle onResum() qui va appeler une mSurfaceHolder.addCallback(mSurfaceCallback); et ce rappel à l'appel startVideo() qui devrait lancer la vidéo, mais rien de commencer..

Donc si quelqu'un a un exemple de comment créer un lecteur vidéo simple avec la dernière LibVLC ou une idée de l'endroit où j'échoue, il serait utile
