Add a speed feature to give the tighter search rangeAdd a speed feature to give the tighter partition search
range. Before partition search, calculate the histogram
of the partition sizes of the left, above and previous
co-located blocks of the current block. If the variance of
observed partition sizes is small enough, adjust the search
range around the mean partition size, which will be tigher.The feature is currently turned on at speed 2. Experiments on
sample youtube clips show on average the runtime is reduced
by 3-7%.For hard stdhd clips :
park_joy_1080p @ 15000kbps : 509251 ms -> 491953 ms (3.3%)
pedestrian_area_1080p @ 2000kbps : 223941 ms -> 214226 ms (4.3%)The PSNR performance is changed :
derf : -0.112%
yt : -0.099%
hd : -0.090%
stdhd :-0.102%Change-Id : Ie205ec5325bf92ec5676c243e30ba9d0adca10f2

Add early termination in transform size searchIn the full-rd transform size search, we go through all transform
sizes to choose the one with best rd score. In this patch, an
early termination is added to stop the search once we see that the
smaller size won’t give better rd score than the larger size. Also,
the search starts from largest transform size, then goes down to
smallest size.A speed feature tx_size_search_breakout is added, which is turned off
at speed 0, and on for other speeds. The transform size search is
turned on at speed 1.Borg test results :
1. At speed 1,
derf set : psnr gain : 0.618%, ssim gain : 0.377% ;
stdhd set : psnr gain : 0.594%, ssim gain : 0.162% ;
No noticeable speed change.
3. At speed 2,
derf set : psnr loss : 0.157%, ssim loss : 0.175% ;
stdhd set : psnr loss : 0.090%, ssim loss : 0.101% ;
speed gain : 4%.Change-Id : I22535cd2017b5e54f2a62bb6a38231aea4268b3f
