I'm curious to know why you include mpeg12.h (here at at some other
places in this patch) ? I can't see anything which would require it.

Moreover, in case you add a dependency to mpeg12.o, you also need to
adjust the Makefile (but I guess this would add lots of ugly, almost
useless dependencies).
Maybe you could find a better place to put the new *_qscale table to
reduce artificial dependencies.
