Then interpreted it that way because it doesn't yet implement b-pyramid.

This afternoon I found mbtree is even faster than no-mbtree (in my very
selective test), which I didn't expect and also is against the pieces of
texts I found on the matter.

My point: if this is backed by the experience of others, the addition of
a no-mbtree option in libavcodec might not even be worth it. Although
I'd be happy to code the three lines ;-)
