Compile faad2 on Android

1. Download the source code from the official website

2. edit a config. h:

3. Compile Android. mk

4. compile.

5. Fixed Point:

The above compilation is a floating point, which can be compiled into a fixed point by opening two Macros in faad/libfaad/common. h:

#define FIXED_POINT#define BIG_IQ_TABLE

Then rinse and compile. On my mobile phone, use a fixed point, which can be 5 times faster.
