a8fbab8697
This commit enabled the usage of 8x8 intra prediction modes on inter frames. There are a few TODO items related to this: 1)baseline entropy need be calibrated; 2)cost of UV need to be done more properly rather than using decision only relying on Y; 3)Threshold for allowing picking 8x8 intra prediction should be lowered to lower than the B_PRED. Even with all the TODOs, tests showed consistent gain on derf set ~0.1% (PSNR:0.08% and SSIM:0.14%). It is assumed that 8x8 intra prediction will help more on large resolution clips, especially with above TODOs addressed. Change-Id: I398ada49dfc32575cfab962a569c2885111ae3ba
