What it may very well be (I can't remember if faad in particular is or isn't) 
that the audio codec is a floating point based one. Similar situations 
happened on my Zaurus (206MHz StrongARM) when initially getting mplayer to 
work, (my page on that has moved (533Alpha->2GHz Athlon 64, being the cause) 
for the moment to  http://156.26.12.150/family/james/mplayer.html, some such 
as the audiocodec change is valid, and some (-aop 
resample:format:resample=44100 is outdated),  I will update it when the 
webpage gets transfered over as well.) and found out that mp3lib was floating 
point.

ffmpeg audio codecs(I think one of the wmas may have fp math, though most 
codecs are safe, and I am not certain on that), libmad is purely integer, ogg 
(see --enable-tremor) can be played with an integer decoder. Almost all if 
not all video codecs are integer based, so there isn't much worry there.
