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
