Abstract:
Recently, virtual reality (VR) and 360deg videos have been increasingly adopted in a wide range of applications. However, the huge sizes of 360 deg videos necessitate the use of powerful compression tools to allow for efficient storage and streaming of these videos. In this article, we compare the performance of four different video codecs, including AV1 and versatile video coding (VVC), when applied to a dataset of 360 deg videos. We conduct our evaluation according to peak signal-to-noise ratio (PSNR)-based 360deg video quality assessment (VQA) metrics. As omnidirectional videos are usually streamed as independent tiles, we also investigate the tiling effect on VVC compression performance by comparing full-frame-based compression to tiled segment compression using grids of 8x8 and 16x16 tiles.
