Why does using -oac copy matter in the non-final passes?  It seems like you
could use -oac copy for the first pass, and then use -oac mp3lame in the
final pass.

What would be faster, is if there was a -oac null option, sort of like -ovc
frameno.  It wouldn't actually encode any audio, just be a filler for things
like bitrate estimating and mutlti-pass encoding.
