论文摘要
借助Covid-19，对数字互动的兴趣已经提高，又将实时（或低延迟）编解码器置于新的光明中。传统上，大多数编解码器研究都集中在编码效率上，而实时编解码器上的文献很少。它显示了如何提供内容的速度会影响延迟和吞吐量。作者介绍了一个新的测试设置，并集成了一个节奏的读者，该测试器允许在与实时媒体捕获相同的条件下运行编解码器。使用VMAF的质量测量以及在25 fps和50 fps的HD和全高清视频序列编码时进行了多个速度测量，以比较H.264，H.265，VP8，VP8，VP9和AV1 CODEC的几种实现的相应性能。
With COVID-19, the interest for digital interactions has raised, putting in turn real-time (or low-latency) codecs into a new light. Most of the codec research has been traditionally focusing on coding efficiency, while very little literature exist on real-time codecs. It is shown how the speed at which content is made available impacts both latency and throughput. The authors introduce a new test set up, integrating a paced reader, which allows to run codec in the same condition as real-time media capture. Quality measurements using VMAF, as well as multiple speed measurements are made on encoding of HD and full HD video sequences, both at 25 fps and 50 fps to compare the respective performances of several implementations of the H.264, H.265, VP8, VP9 and AV1 codecs.
