Steps to reproduce:
1. Open attached project
2. Build & Run to an Android device
3. Tap "seek" until the video with skip on drop set to false hangs or starts from the beginning of the video with double the speed

Expected result: both cubes should skip to the same point and continue playing at normal speed
Actual result: video player with 'skip on drop' set to false will lock up about 50% of the time, isPlaying will return true but the time will not advance. About 30% of the time the video will start from the beginning and play at double speed, the rest of the time the video will seek correctly.
