exoplayer 加载具有 (.mkv) 格式的大视频文件有点慢

Question

我们在我的一个视频播放器应用程序中集成了 exoplayer 来播放本地视频

EXOPLAYER 版本：2.11.0

我们观察到 MP4 可以通过前进和后退视频完美播放，但是当 尝试播放大 MKV 文件时，Exoplayer 最初在我们启动 MKV 视频时卡住了，而当前进和后退 mkv 视频时，播放器卡住了大约 10 秒，然后播放视频

我们已经通过 android studio profiler 工具进行了检查，观察到当我们播放 MKV 视频时，内存消耗增加了 1.1 GB 以上，但当我们播放 MP4 视频时，内存消耗约为 600MB

当我们转发视频后，我们得到了关注logcat
