[MEncoder-users] x264 file playback is too slow!

This options seems to be broken (unless I made a dumb mistake). 

I did

 mplayer -frames 3000 k3b_image.iso -ao pcm:file=k3b.wav -vc null -vo
null -benchmark

and it carried on encoding way past 120 seconds until I killed it.  The
film is 25 fps.

Also, from a later post I think that this method is generally buggy 
(slow and complaining for no reason while not stressing cpu or disk).
