b5ea2fbc2c
This patch attempts to improve the handling of CBR streams with respect to the short term buffering requirements. The "buffer level" is changed to be an average over the rc buffer, rather than a long running average. Overshoot is also tracked over the same interval and the golden frame targets suppressed accordingly to correct for overly aggressive boosting. Testing shows that this is fairly consistently positive in one metric or another -- some clips that show significant decreases in quality have better buffering characteristics, others show improvenents in both.
