Abstract: This paper compares the effectiveness of different projections for different 360-degree videos and codecs, including AV1, HEVC, VP9, and AV. Content for 360 video is especially challenging because using codecs on reprojections magnifies video-stream errors. For this reason, we tested different projections to determine their stability over different encodings. Our results came from performance measurements using end-to-end metrics such as PSNR, SSIM and VMAF as well as subjective assessment of static viewports.
Keywords: spherical video, 360 video, video coding, AVC, HEVC, AV1, ERP, cubemap, barrel.
