I just did a profile on the PPC mplayer - the following are the top few
routines. The last one post is mp_msg which is the routine which prints
message - all the rest are RealAudio decode ("cook") - and the top 3
have a lot of floating point operations. I think they may have to be
rewritten to work fast on ARM if (as I suspect) the ARM processor has
no native floating point.
