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.
