Fix uninitialized mesh feature for BEST mode
At BEST encoding mode, the mesh search range wasn't initialized for
non FC_GRAPHICS_ANIMATION content type, which actually/mistakenly
used speed 0's setting. Fixed it by adding the initialization.
There were 2 ways to fix this. Patchset 1 set to use speed 0's setting
for non FC_GRAPHICS_ANIMATION type. This didn't change BEST mode's
encoding results much, and only a couple of clips' results were changed.
Borg result for BEST mode:
avg_psnr: ovr_psnr: ssim: encoding_spdup:
lowres2: -0.004 -0.003 -0.000 0.030
midres2: -0.006 -0.009 -0.012 0.033
hdres2: 0.002 0.002 0.004 0.015
Patchset 2 set to use BEST's setting for non FC_GRAPHICS_ANIMATION type.
However, the majority of test clips' BDrate got changed up to
~0.5% (gain or loss), and overall it didn't give better performance
than patchset 1. So, we chose to use patchset 1.
