Do you see (libvo-aacenc.o) reference above?
IMHO it's obvous that:
-- libvo-aacenc is a part of libavcodec.a, not the vo-aac library;
-- libvo-aacenc.c is compiled OK.

The vo-aac library itself is already built and placed into the proper path 
within /usr/local/lib.

ff_af* functions, mentioned in the error message, are defined in the 
libavcodec/audio_frame_queue.c

The only I've noticed is that ff_af* references are missing in the 
libavcodec.v It that correct?
Though I've tried to insert them, but with no luck.

Any help would be appreciated.

Thank you.
