  "message": "Fix bottom ref condition for intra prediction in cb4x4\n\nResolve a rare enc/dec mismatch issue triggered by the 4x4 chroma\nblock size in sub8x8 block coding.\n\nTo avoid using 2x2 chroma block size, it always uses the top-left\n4x4 luma block coding information to predict the 4x4 chroma block.\nThe rest 3 4x4 luma blocks will be coded independently without\ncoding the collocated chroma blocks.\n\nThe compression performance gains are 1.45% for lowres set (down\nfrom 2.4% of the original cb4x4 design).\n\nChange-Id: Iff560fcab172ed4219434d5174c4d8dfbbb04135\n",
