video and audio lagging

[Anton Vasiljev]

Hi all, I use libvpx and vorbis libraries to make webm stream from android camera and mic.
I enable neon support when building libs for android.
 My LibVpxEncConfig config:

vpxConfig = new LibVpxEncConfig(640, 480);
vpxConfig.setTimebase(1, 1000000000);
vpxConfig.setThreads(1);
vpxConfig.setRCTargetBitrate(2000);
vpxConfig.setRCMinQuantizer(10);
vpxConfig.setRCMaxQuantizer(30);
vpxConfig.setKFMinDist(0);
vpxConfig.setKFMaxDist(50);
vpxConfig.setRCUndershootPct(95);
vpxConfig.setRCBufInitialSz(400);
vpxConfig.setRCBufOptimalSz(500);
vpxConfig.setRCBufSz(600);

I`m set cpu used to -12 and framerate to 10.
Record audio from mic with sample rate 44100 and 16 bps.
In attached file you will see result. I`m don`t undestand why this lagging exist.
My phone is moto g.
