You need to compile FFmpeg with AMR support (--enable-amr_nb

--enable-amr_wb)

AMR WB FLOAT NOTICE ! Make sure you have downloaded TS26.204

V5.1.0 from

http://www.3gpp.org/ftp/Specs/archive/26_series/26.204/26204-510.zip

and extracted the source to libavcodec/amrwb_float

AMR NB FLOAT NOTICE ! Make sure you have downloaded TS26.104

REL-5 V5.1.0 from

http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26104-5??.zip

and extracted the source to libavcodec/amr_float

and if u try this on an alpha, u may need to change Word32 to int in
