用户生成的HDR游戏视频流:数据集、编解码器比较和挑战

User Generated HDR Gaming Video Streaming: Dataset, Codec Comparison and Challenges

Nabajeet Barman, Maria G Martini

摘要:

游戏视频流媒体服务于过去数年大幅增长,更高分辨率、更高帧速率及HDR游戏视频越来越多地在游戏社区中被采用。由于游戏内容本身与非游戏内容不同,因此必须评估现有编码器的性能,以帮助理解此类服务的带宽要求,并进一步提高此类编码器的压缩效率。为此,我们在本文中介绍了GamingHDRVideoSET,一个由18个10位UHD-HDR游戏视频和使用四种不同编解码器编码的视频序列组成的数据集,以及它们的客观评估结果。该数据集可在[待论文验收后添加]在线获得。此外,本文讨论了最广泛使用的实际编码器的编解码器压缩效率,即,x264(H.264/AVC)、x265(H.265/HEVC)和libvpx(VP9),以及最近提出的10位UHD-HDR游戏内容编码器libaom(AV1)。我们的研究结果表明,最新的压缩标准AV1的压缩效率最高,其次是HEVC,H.264和VP9。

英文摘要:

Gaming video streaming services have grown tremendously in the past few years, with higher resolutions, higher frame rates and HDR gaming videos getting increasingly adopted among the gaming community. Since gaming content as such is different from non-gaming content, it is imperative to evaluate the performance of the existing encoders to help understand the bandwidth requirements of such services, as well as further improve the compression efficiency of such encoders. Towards this end, we present in this paper GamingHDRVideoSET, a dataset consisting of eighteen 10-bit UHD-HDR gaming videos and encoded video sequences using four different codecs, together with their objective evaluation results. The dataset is available online at [to be added after paper acceptance]. Additionally, the paper discusses the codec compression efficiency of most widely used practical encoders, i.e., x264 (H.264/AVC), x265 (H.265/HEVC) and libvpx (VP9), as well the recently proposed encoder libaom (AV1), on 10-bit, UHD-HDR content gaming content. Our results show that the latest compression standard AV1 results in the best compression efficiency, followed by HEVC, H.264, and VP9.
