Please don't top-post. We prefer interleaved inline posting on these

I queried this as it is very unusual behaviour. The only things that I
can note is that the GCC 4.1.x series is quite old (though I don't see
why that would cause issue here) and you appear to be running as root
unnecessarily.

Try compiling and running FFmpeg as a regular user. Also make sure you
have the most recent release of FAAD and FAAC. Sometimes library
interface code in FFmpeg gets updated to support newer versions and
the older code is dropped. Also check that your library paths are
correct and that you have the correct permissions on your library
files, though I would expect some undefined symbol errors to appear
really.
