Bit old post but whatever.  
This works on APDE.  
But not in the preview! You have to make an app.

This example requires a “test.mp4” in the data folder to load into the mediaplayer.

Exporting i don’t know.

```auto
import android.media.MediaMetadataRetriever;
import android.os.Handler;
import android.os.HandlerThread;
import android.os.Looper;
import android.app.Activity;
import android.view.ViewGroup;
import android.view.View;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.media.MediaMetadataRetriever;
import android.media.MediaPlayer;
import android.content.res.Resources;
import android.content.res.AssetFileDescriptor;
import android.content.res.AssetManager;
import android.content.Context;
import android.os.Environment;

AssetFileDescriptor afd;
Context context;
Activity act;
SurfaceView mySurface;
SurfaceHolder mSurfaceHolder;
MediaMetadataRetriever metaRetriever;
MediaPlayer mMediaPlayer;
//String sdcard = new String(Environment.getExternalStorageDirectory().getAbsolutePath());

String fileName = "test.mp4";
// this one is in the data folder.
// for a other path/file adjust accordingly. 

void setup() {
  size(displayWidth, displayHeight, P2D);
  act = this.getActivity();
  context = act.getApplicationContext();
  Looper.prepare();
  mMediaPlayer = new MediaPlayer();
  try {
    // here the file gets prepared/opened
    afd = context.getAssets().openFd(fileName);
    
    MediaMetadataRetriever metaRetriever = new MediaMetadataRetriever();
    metaRetriever.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
    String height = metaRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT); 
    if (int(height) < 2) {
      throw new IOException();
    }
  }
  catch (IllegalArgumentException e) {
    e.printStackTrace();
  }
  catch (IllegalStateException e) {
    e.printStackTrace();
  } 
  catch (IOException e) {
    e.printStackTrace();
  }

  mySurface = new SurfaceView(act);
  mSurfaceHolder = mySurface.getHolder();
  mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
  mSurfaceHolder.addCallback(new SurfaceHolder.Callback() {
    @Override
      public void surfaceCreated(SurfaceHolder surfaceHolder) {
      mMediaPlayer.setDisplay(surfaceHolder);
    }

    @Override
      public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i2, int i3) {
      mMediaPlayer.setDisplay(surfaceHolder);
    }

    @Override
      public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
    }
  }
  );
  startVideo();
}

void startVideo() {
  act.runOnUiThread(new Runnable() {
    public void run() {
      try {
        
        // here the file gets actually loaded into the mediaplayer
        mMediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
        
        mSurfaceHolder = mySurface.getHolder();
        mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
        mMediaPlayer.prepare();
// act.addContentView(mySurface, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT));
        act.addContentView(mySurface, new ViewGroup.LayoutParams(400,400));
        if (mMediaPlayer.isPlaying() == false) {
          mMediaPlayer.start();
        }
      }
      catch (IllegalArgumentException e) {
        e.printStackTrace();
      }
      catch (IllegalStateException e) {
        e.printStackTrace();
      } 
      catch (IOException e) {
        e.printStackTrace();
      }
    }
  }
  );
};

void draw() {
}

void onPause() {
  if (mMediaPlayer!=null) {
    mMediaPlayer.release();
    mMediaPlayer = null;
  }
  super.onPause() ;
}

void onStop() {
  if (mMediaPlayer!=null) {
    mMediaPlayer.release();
    mMediaPlayer = null;
  }
  super.onStop() ;
}

void onDestroy() {
  if (mMediaPlayer!=null) {
    mMediaPlayer.release();
    mMediaPlayer = null;
  }
  super.onDestroy() ;
}

void onResume() {
  super.onResume() ;
}

```

sorry for the late reply but I don’t always have internet.  
and unfortunately I can’t help you with exporting images from the MediaPlayer…  
but try a search on stackexchange for something like: ‘android save image from MediaPlayer’ and you should get some helpful results 😉
