  "message": "Rework forward txfm/quantization skip system in RTC coding mode\n\nThis commit allows more aggressive decision to skip forward\ntransform and quantization for luma component in RTC coding mode.\nThe chroma components remains going through the normal coding\nroutine, since they are not included in the non-RD mode search\nprocess.\n\nIt reduces the runtime cost by 2% - 10%.
