This is a profile summary i took a while ago, on theora as it was in 
alpha6 (includes the mmx optimisations)

One thing to note is it doesn't necessarliy show every function, since 
some stuff gets inlined into the caller and hence doesn't appear in this 
list (it's included in the caller instead). But it does show the basic 
gist of it.

Also, this was on a small (320x240) video of roughly 1 min duration.
