Increase TPL stats block size for res < 720p
Increased TPL stats block size to 16x16 for resolution < 720p to reduce
memory usage without affecting encoding speed and quality.
Borg test results:
avg_psnr: ovr_psnr: ssim:
speed0:
midres: 0.037 0.044 -0.008
lowres: -0.006 0.003 -0.035
speed 1:
midres: -0.003 -0.008 -0.013
lowres: -0.009 -0.026 -0.018
Memory reduction:
midres(480p): 17.2%
lowres(cif): 13.8%
No impact on encoding speed.
