I think it is not safe to use
+        double elapsed_time = (double)h->fenc->i_frame / rcc->num_entries;
+        double abr_buffer_adj = abr_buffer * (1-elapsed_time);
when we not doing the 2pass (it would result in division by zero). And
so it would results in incorrect value of abr_buffer_adj which you
also use in 1pass ABR.
