Optimize x265 Rate Control : An Exploration of Lookahead in Frame Bit Allocation and Slice Type Decision
To improve the Rate-Distortion (R-D) quality, x265 rate-control made a variety vital decisions, such as scene cut detection, slice type decision, and coding-unit quantization parameter (QP) offsets, leveraging on lookahead to evaluate the information propagation through the current and the near futu...
