I see, thanks Alex. But I still do not see the volume level report.
The glitch I've notice is that mencoder's "-af volnorm" encodes first
second or so at original volume level, then it boost/lowers the volume
based on target aplitude (I assume). It doesn't sound very smooth  :(
So I want mencoder to report vol level on 1st pass, and on second pass
a bash script will generate "-af volume=xx:xx" based on it.

Thank you.
Dennis.
