Video Force VideoPlayer memory to be released?

Hello!
I've got an ios app that will basically play an unlimited number of different videos. I run into a problem where, after X amount of videos, the app crashes due to lack of memory. I call this when switching videos:

Code (CSharp):

1.                 var _videoPlayer = gameObject.GetComponent<VideoPlayer>();
2.                 _videoPlayer.Stop();
3.                 Destroy(_videoPlayer);

According to the documentation, I don't even need to call Destroy() as Stop() will release all the memory by itself. However this doesn't seem to be true, as every time I load a new video the memory usage goes up significantly. Does anyone know a good way to force this memory to be released? Thanks!
