You need a52dec:
liba52 is a free library for decoding ATSC A/52 streams. The A/52
standard is used in a variety of applications, including digital
television and DVD. It is also known as AC-3.

a52dec should be (optional) ffmpeg dependency.

$ ldd libmp3_decoder.so
linux-gate.so.1 => (0xffffe000)
libmad.so.0 => /usr/lib/libmad.so.0 (0xb7f1b000)
