First I will post my results after using the x264opts Hendrik

<p>You could directly call the built-in stagefreight avc decoder,
this approach does not introduce extra latency. But the number
of instances is limited - three or four, not more.</p>

Android's native decoder? It may be more optimized for the

faster.<br>
