xvid uses a 'plugin' concept allowing one to hook into the encoder.
take a look at rc_2pass1_after() within plugins/plugin_2pass1.c,
to see how we output the first-pass i/p/b statistics.

to get the second pass "final" statistics, you could modify rc_2pass2_after()
within plugins/plugin_2pass2.c to output the i/p/b statistics.
