Okay i will consider that if i am not able to speedup ffmpeg decoding.
First I will post my results after using the x264opts Hendrik provides (
"zerolatency,fastdecode" ).

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.
