Confirmed that ref=3 bframes=3 bref=1 produces Pyramidal B References. Thanks!

Hi, perhaps you didn't add enough reference frames. You need at least 3 refs to have a reference B frame. Try with 'ref=3 bframes=3 bref=1'. Note that adding more than 1 B frame typically degrades quality at the moment, even with B pyramid. We need the lookahead to determine a good B frame layout. This is being implemented.
