Use direct submit decoding for MediaCodec. Based on my profiling of a few devices, dequeueInputBuffer and queueInputBuffer don't take much time anyway. It allows us to stop our semi-busy looping which saves power. The depacketizer can avoid expensive synchronization and additional context switching which costs time and CPU cycles.
