Abstract

In this work, we introduce 360EAVP, an open-source Web browser-based application for streaming and visualization of 360-degree edited videos on head-mounted displays (HMD). The proposed application builds upon the Virtual Reality Tile-Based 360-degree Player (VDTP) by adding new functionalities. Specifically, this paper explains the main features introduced by 360EAVP, which are: 1) operation on HMDs based on real-time user's viewport; 2) dynamic editing via "snap-change" or "fade-rotation" combined with "blinking"; 3) visibility evaluation of user's Field of View with respect to the player's cubic projection (for purposes of tile requests); 4) incorporation of editing timing information into the operation of the ABR algorithm; 5) viewport prediction module based on either linear regression or ridge regression algorithms; and 6) data collection and log module during video playback. The introduced application can be freely used to support research on many topics such as optimization of tile-based 360-degree edited video streaming, psycho-physical experiments, dataset generation, and ABR algorithm development, to name a few.
