New option: "B-frame pyramid" keeps the middle of 2+ consecutive B-frames as a reference, and reorders frame appropriately.

Disable deblocking filter in frames of sufficiently low QP that it would have no effect. (Saves a little CPU time in the decoder.)

Loren Merritt authored Feb 17, 2005

Improved 2pass bitrate predictor. No real change most of the time, but allows correct ratecontrol on some pathological videos that used to diverge completely. Also improves prediction when 2nd pass bitrate is very different from 1st pass.
The new qscale2bits() has no simple inverse, so I also had to change rc_eq to output qscale instead of bits.
