Your commandline fails when you try to encode -oac faac. Before
30/04/2013 the error was only issued when someone tried to encode to
codec_id AV_CODEC_ID_AAC.

I tracked down when I patched my FFmpeg and made the error not fatal
anymore. That was for FFmpeg 1.2.1, which contained this patch by Carl
Eugen:
http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=b448c0a68d0cc7dfef736267dfdaed0e213c020b

There is a chance that the original FFmpeg 1.2 still works OK, when you
compile it into MEncoder. If you want to try it:
http://ffmpeg.org/releases/ffmpeg-1.2.tar.bz2

Yes, it needs another compilation but it would be interesting to know if
FFmpeg 1.2 produces correct files, where later FFmpeg's do not.
