You can try this to extract frame:

package com.example.androidmediametadataretriever;

import android.graphics.Bitmap;
import android.media.MediaMetadataRetriever;
import android.os.Bundle;
import android.widget.ImageView;
import android.app.Activity;

public class MainActivity extends Activity {

 String uri = "/storage/sdcard0/DCIM/100MEDIA/VIDEO0007.mp4";

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  ImageView capturedImageView = (ImageView)findViewById(R.id.capturedimage);

  MediaMetadataRetriever mediaMetadataRetriever = new MediaMetadataRetriever();

  mediaMetadataRetriever.setDataSource(uri);
  Bitmap bmFrame = mediaMetadataRetriever.getFrameAtTime(5000000); //unit in microsecond
  capturedImageView.setImageBitmap(bmFrame);
 }

}
