高效视频编码（HEVC）压缩效率的提高伴随着计算复杂性的大幅增加，最近研究人员通过降低复杂性和缩放方法来解决这一问题。然而，帧或图片组 (GOP) 级别的编码时间控制仍然是一个必须研究的悬而未决的问题。在这项工作中，对根据先前工作的发现和技术创建的一组配置进行率失真复杂性分析。所提出的控制系统使用最佳的 27 种配置来调整每个 GOP 的编码时间，编码时间减少高达 84.5%，目标时间和编码时间之间的平均差异为 4.1%。
The improved compression efficiency of High Efficiency Video Coding (HEVC) comes with large increases in computational complexity, which has been lately dealt by researchers with complexity reduction and scaling methods. However, encoding time control at frame or Group of Pictures (GOP) level is still an open issue that must be investigated. In this work, a Rate-Distortion-Complexity analysis is performed upon a set of configurations that have been created based on findings and techniques of previous works. The proposed control system uses the best 27 configurations to adjust the encoding time per GOP and yields encoding time reductions of up to 84.5% with an average difference between target and encoding times of 4.1%.
