Great work!
I like the runtime code generation idea :)

Btw, I've fixed bpp (now it means bits/pixel), and -fs option of -vo x11.

Tested in 16 and 32bpp, both works well.

What about 24bpp?
I've found that current bottleneck is video bandwith.
About 60% (at 32bpp) is spent in blitting (XShmPutImage/XPutImage)
We could win 15% here if using 24bpp.
