These samples are too short, so I'm afraid that I'm measuring ffmpeg's
startup time rather than AAC decoding (it takes about .2 seconds to
decode the file, from launch of FFmpeg to exit).

Would it work with any iTunes-encoded AAC file? If not, maybe you
should direct me to a bigger sample from Mplayer's samples

Only a very small fraction of our DNA does anything; the rest is all
comments and ifdefs.
