<pre>When there are many frames or the frames are large, the memory cache keeps asks for destroying the decoded frames. Having the decoding happens at the time of drawing makes the animation stuttered. To resolve this problem, the image decoding should be moved form the main thread to a operate thread. And the frame to be displayed should be requested in advance such such that when it the frame is drawn, its decoded data is ready.</pre>
