Slow MP3 decoding #2

Hello Yang.
Thanks a lot for the code.

MP3 decoding is very slow (a 300 sec file takes more than 20 seconds to decode). Wav decoding is twice as fast.
Is there any way to speed up this process?

I've found reports that MediaCodec itself is slow, but I'm not sure. The technical messages were about earlier versions of Android.

Recommend use ffmpeg decoding mp3 to wav data, and use this code generates waveform from wav data.
