Actually the movie is 23.975 FPS, But the movie is only 9.6M (9967485 byte to
be exact), so by a naive guess, the data mplayer need to decode is 6.5
kbytes/s, and the data for every frame is about 300 bytes. Considering the
movie is almost static, I still feel unnatural for such a small amount of
data eats so much cpu time.
