Flare是一个实用的系统，用于在智能手机上播放360度视频。它采用自适应视口方法，只获取全景场景中覆盖观众即将感知的部分。Flare包含了一个端到端流媒体管道的新框架，引入了创新的流媒体算法，并带来了许多系统级优化。在我们的演示中，我们将展示Flare在视频质量方面大大优于传统的与视口无关的流媒体算法。我们还将邀请观众使用Flare观看吸引人的360度视频。
Flare is a practical system for streaming 360-degree videos on smartphones. It takes a viewport-adaptive approach, which fetches only portions of a panoramic scene that cover what a viewer is about to perceive. Flare consists of a novel framework for the end-to-end streaming pipeline, introduces innovative streaming algorithms, and brings numerous system-level optimizations. In our demo, we will show that Flare substantially outperforms traditional viewport-agnostic streaming algorithms in terms of the video quality. We will also invite the audience to use Flare to watch attractive 360-degree videos.
