  "message": "Turn on the use of upsampled refs for ext-refs\n\nWithout this patch, the experiment of ext-refs showed almost no coding\ngains compared to the baseline. This is because when ext-refs is on, the\nuse of upsampled reference is off.\n\nWith this patch, the ext-refs experiment works with the upsampled\nreferences and shows coding gains in Overall PSNR as follows, with ~5%\nslow down for encoding time:\n\nlowres: Avg - -0.965;  BDRate - -0.844\nderflr: Avg - -0.847;  BDRate - -0.669\n\nNote that the previous patch a912c6ec314d816767a4c3eb4e5e1bddcc4c1186\nthat \"Make LAST_FRAME always point to the newly coded frame in ext-refs\"\nmade ext-refs work with the upsampled refereces.\n\nChange-Id: Id79248d71760109fb9198af4f45718b17455555f\n",
