Native内存是不是有泄露

我用的Andorid 0.8.4版本的demo进行测试,持续的播放视频，然后退出播放，反复操作，一边用Android Studio内存查看器查看内存，发现一个很奇怪的现象，Native的内存占用很高，即便是退出了播放，也还是很高，但是并不是说一直涨，测试到后面Native层的内存在不播放视频的情况下，占用都达到了60M，这是什么原因，是泄露了吗。
PS:播放本地视频尤为明显，尤其是播放大分辨率的视频，很容易出现这个情况。

Start by reproducing the report with the Android 0.8.4 demo, repeatedly playing and exiting local high-resolution videos while watching native memory in Android Studio's memory viewer. Trace native allocations through playback teardown and compare whether memory is reclaimed between cycles. Done means identifying a reproducible leak or documenting why the retained native memory is expected, with measurements.
