As far as I understand, in this context the term Video Object Plane can be
used interchangeably with frame, hence B-VOP = B-frame.
See e.g.

Therefore your setting would be:

	'bf integer (encoding,video)'

	    Set max number of B frames.

There are some others that dynamically influence B-frame decisions. Some
have yielded quality and/or compression benefits for me at times.
E.g.

	'b_strategy integer (encoding,video)'

	    Set strategy to choose between I/P/B-frames.

	'-weightb integer'

	    Weighted prediction for B-frames.

etc.
