Please find below code for both Option 1 & Option 2.
Please note -
1) Use your actual variable instead of dummy.
2) Position of thumbnails should be move as per mouseMove on seekBar. Get the mouse X posion and set the xpos of your thumbnail which contain either Video object or image display holder.
