You need install libopencore-amrnb and compile ffmpeg with supporting
it to get amrnb decoding and encoding, see: ./configure --help
(.configure --enable-libopencore-amrnb)
Installing libvo-amrwbenc and compile ffmpeg with supporting it can get
amrwb encoding (./configure --enable-libvo-amrwbenc)

To check which codecs your ffmpeg binary has supported, see: ffmpeg
