I'm using VLC-Android in order to play H264 RTSP live stream in my android application, the following code successfully renders the stream video onto the surface view:

MediaPlayer mMediaPlayer = new MediaPlayer(VLCInstance.get());

SurfaceView mSurfaceView = (SurfaceView) findViewById(R.id.player);



final IVLCVout vlcVout = Constants.mMediaPlayer.getVLCVout();

vlcVout.detachViews();

vlcVout.setVideoView(mSurfaceView);

vlcVout.setWindowSize(mSurfaceDims.getWidth(), mSurfaceDims.getHeight());

vlcVout.attachViews();

mSurfaceView.setKeepScreenOn(true);



Media media = new Media(VLCInstance.get(), Uri.parse(path));

mMediaPlayer.setMedia(media);

mMediaPlayer.play();

VLCInstance.java:

package bi.anpr.vlc;



import android.content.Context;

import android.util.Log;



import org.videolan.libvlc.LibVLC;

import org.videolan.libvlc.util.VLCUtil;



public class VLCInstance {

    public final static String TAG = "VLC/Util/VLCInstance";



    private static LibVLC sLibVLC = null;



    /** A set of utility functions for the VLC application */

    public synchronized static LibVLC get() throws IllegalStateException {

        if (sLibVLC == null) {

            final Context context = VLCApplication.getAppContext();

            if(!VLCUtil.hasCompatibleCPU(context)) {

                Log.e(TAG, VLCUtil.getErrorMsg());

                throw new IllegalStateException("LibVLC initialisation failed: " + VLCUtil.getErrorMsg());

            }



            try{

                sLibVLC = new LibVLC(context);

            }catch (Throwable e){

                e.printStackTrace();

            }



        }

        return sLibVLC;

    }



    public static synchronized void restart(Context context) throws IllegalStateException {

        if (sLibVLC != null) {

            sLibVLC.release();

            sLibVLC = new LibVLC(context);

        }

    }

}

The problem is that the org.videolan.libvlc.MediaPlayer renders the video on the SurfaceView after calling play() without any event that helps you to grab the current frame on the view, where i need to get the current frame each interval of time to perform some image processing on it.

So is it possible using vlc-android-sdk to grab current frame, into a buffered image or an OpenCV Mat, while playing live streams or local video resources?

Note that it is possible with java (desktop vlcj) through the DirectMediaPlayer class.

Thanks in advance!!
