  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.
