  "message": "Preload reference area in sub-pixel motion search (real-time mode)\n\nThis change implemented same idea in change \"Preload reference area\nto an intermediate buffer in sub-pixel motion search.\" The changes\nwere made to vp8_find_best_sub_pixel_step() and vp8_find_best_half\n_pixel_step() functions which are called when speed \u003e\u003d 5. Test\nresult (using tulip clip):\n\n1. On Core2 Quad machine(Linux)\nrt mode, speed (-5 ~ -8), encoding speed gain: 2% ~ 3%\nrt mode, speed (-9 ~ -11), encoding speed gain: 1% ~ 2%\nrt mode, speed (-12 ~ -14), no noticeable encoding speed gain\n\n2. On Xeon machine(Linux)\nTest on speed (-5 ~ -14) didn\u0027t show noticeable speed change.\n\nChange-Id: I21bec2d6e7fbe541fcc0f4c0366bbdf3e2076aa2\n",
