Yeah, but is that five pictures over twenty minutes at 29.97 FPS, or  
at 0.0042 FPS? Unless you encoded it at 0.0042 FPS (that is, a grand  
total of five frames in twenty minutes), MPlayer will have to decode  
all the frames, even if they're identical, or even if they have  
little to no motion. And at 1024x768 resolution, that's a fair chunk  
of data to decode too.

A better test might be encoding Team Orange's Elephant's Dream. It  
will give you a more representative snapshot of what kind of CPU  
usage you should come to expect out of H.264.
