Ich versuche, mit der letzten LibVLC einen Video-Player für eine Android-App zu erstellen.

Das Problem ist, dass ich nicht weiß, wie diese Bibliothek funktioniert und ich keine Probe finde, die mir hilft (wie es hier heißthttps: //bitbucket.org/edwardcw/libvlc-android-sampl)

So versuche ich selbst den Video-Player zu erstellen:

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 {

Zum Starten des von mir aufgerufenen videoPlayerActivitystart(Context context, Uri uri) und es wird die Aktivität erstellen.

Um diesen Code fortzusetzen:

Nach demoncreat() Ich rufeonResum() das wird ein @ aufrufmSurfaceHolder.addCallback(mSurfaceCallback); und dieser Rückruf callstartVideo() das sollte das Video starten, aber nichts starten ..

Also, wenn jemand ein Beispiel dafür hat, wie man einen einfachen Videoplayer mit der letzten LibVLC erstellt, oder eine Idee, bei der ich versage, wäre es hilfreich.
