Android MediaCodec decode h264 raw data latency issue
<p>I have tried to use MediaCodec to decode 1080p h264 raw data.
But I found the latency is between 45ms~65ms with my SONY Z3(5.1.1).
Is possible to reduce the latency?
My frame is IPPP and GOP is 15, Have any h264 sps flag will effect the latency?</p>

<p>And I have another question, how to change the orientation of surface let the frame show in 90,180 or 270 degree.</p>

<p>I put my test project source in following google drive link.
And the h264 raw data is in test_code\res\raw .</p>
