摘要

人们对相对新颖、开放、免版税的AV1(开放媒体联盟视频)标准寄予厚望。目前，AV1格式有许多新的变体。它专为高效的视频网络传输和高质量的视频传输而设计。AV1被识别为bb0 ?它是VP9格式的继承者。到目前为止用于测试AV1的参考工具之一是libaom- AV1。然而，由于其耗时的性能，现在有不同的可用的独立解决方案用于实验分析。这里有一个这样的解决方案:amedia ?为了分析基于恒定质量约束因子的质量评价，对aomencs - av1独立aomencs进行了测试。对于相同帧率的各种4k视频内容，计算了三个不同的度量。此外，rav1e的实现对相同的视觉数据进行了测试，其中rav1e-AV1也代表了AV1视频编码器，在大多数情况下被认为是可靠和合适的，libaom不适用。本文给出了aomencs - av1与rav1e-AV1的比较结果。

Video coding and constant quality evaluation using 4k aomenc-AV1 and rav1e-AV1 formats

It is much expected from the relatively novel, open, royalty-free AV1 (Alliance for Open Media (AOMedia) Video 1) standard. At this moment, there are many new variants of AV1 format. It is designed for efficient video internet delivery and high-quality video transmission. AV1 is recognized as Google?s VP9 format successor. One of the reference tools used so far for testing AV1 is libaom- AV1. Nevertheless, due to its time-consuming performance, there are now different available standalone solutions for experimental analysis. Here, one such solution AOMedia?s standalone aomenc (aomenc-AV1) is tested in order to analyze quality assessment based on constant quality constraint factor. Three different metrics are calculated for various 4k video content of the same frame rate. Moreover, rav1e implementation was tested for the same visual data, where rav1e-AV1 also represents an AV1 video encoder, which is considered reliable and suitable in most cases, where libaom is not applicable. In this paper, the comparison results between aomenc-AV1 and rav1e-AV1 are shown.
