  "message": "Modify block transform skipping check\n\nBlock transform skipping was implemented based on DCT\u0027s energy\nconservation property. Modified the thresholds using zero bin\nparameters. AC and DC coefficients were checked separately to\nallow better identifying of skippable blocks.\n\nBorg test at speed 3 showed:\nstdhd set: psnr gain: 0.153%, ssim gain: 0.051%;\nderf set: psnr gain: 0.023%, ssim gain: 0.036%\n\nFor most test clips, the encoding speedup is 1% - 2%.\nparkrun(720p): 7.5% speedup, park_joy(1080p): 3.5% speedup.\n\nChange-Id: If28eb81113a077414f5ca7b021c14f9069b373bb\n",
