.B bframes=<0\-16>
number of consecutive B-frames between I- and P-frames (default: 0)
maximum number of consecutive B-frames between I- and P-frames (default: 0)
.
.TP
.B (no)b_adapt
Automatically decides when to use B-frames and how many, up to the maximum
specified above (default: on).
If this option is disabled, then the maximum number of B-frames is used.

.TP
.B b_bias=<-100\-100>
Controls the decision performed by b_adapt.
A higher b_bias produces more B-frames. (default: 0)
