I want to encode a

I'm a new user to mplayer and I want to encode a .wmv (Microsoft Windows 
Media 9 video) video file with h.264 codec. I use the folowing command 
line to do the job. It's work, of course, but it's really slow (2.04 
fps). Also I receive a lot of "31 duplicate frame(s)!" error.

/mencoder testing4.small.wmv -o /dev/null -passlogfile passfile.log -ovc 
x264 -x264encopts 
-oac faac -faacopts br=128:mpeg=4:object=2 -channels 2 -srate 48000 
-vf-add scale=640:360 -vf-add pullup,softskip -vf-add harddup/

If I add the argument -ofps 30.0 the process run normally with 22.4 fps 
and there is no more duplicate frames.

Does any body can explain me the reason why mencoder behave like that?
