  "message": "Fix for low-delay: properly set golden frame level\n\nEarlier, the first frame of type GF_UPDATE (from 2nd subgop onwards)\nwas ignoring the layer_depth specified by the subgop config, and was\nsetting the layer_depth as 0 always.\n\nNow we set the layer_depth of these frames properly by reading prev_last\nstep config. This is necessary as GF_UPDATE frame is encoded as first\nframe of next subgop.\n\nBefore vs After CTC BDRate (Ovr PSNR):\n\n- With --use-fixed-qp-offsets\u003d1:\nlowres2:         -11.039\nmidres2:         -12.445\nobjective1-fast: -12.420\n\n- With --use-fixed-qp-offsets\u003d0:\nlowres2:         -0.297\nmidres2:         -0.290\nobjective1-fast: -0.231\n\nWithout vs With fixed QP offsets CTC BDRate (Ovr PSNR):\n- Before: +10.779 to +14.301\n- After:  -1.183 to  +0.204\n\nBUG\u003daomedia:2832\n\nChange-Id: I4f60adf8e60d65004ce297879f56bfb6a81c1ed6\n",
