Highlights:
• A frame level QP and λ allocation named reference structure determined parameter (RSDP) algorithm is proposed to satisfy GoP length 4, 8, and 16 respectively.
• A GoP level QP and λ allocation named adaptive quantization parameter offset (AQPO) algorithm is proposed to deal with low-delay configuration.
• Both RSDP and AQPO algorithms have achieved remarkable coding performance under BD-rate statistic units.
