if necessary you should write an af_lavc to encode to mp2; this filter 
should be automatically
inserted  in the audio chain (for sure someone already began to write it).
BTW, if your audio source is already in mp2 format you can use
-ac hwmpa (mpeg audio pass through),
but be aware that this decoder really sucks (surely my worst code in 
mplayer :) )
