Abstract
Example bullet screen play methods and apparatus are described. One example bullet screen play method includes receiving a bullet screen enabling instruction for a target video, where the bullet screen enabling instruction instructs to play a bullet screen in a virtual reality (VR) bullet screen manner. An annular transparent bullet screen layer is drawn in a preset orientation of a video layer of the target video in response to the bullet screen enabling instruction, where a first height of the video layer is less than a second height of the bullet screen layer. Bullet screen information of a real-time bullet screen of the target video is obtained. Three-dimensional coordinates of the real-time bullet screen on the bullet screen layer are calculated based on the bullet screen information. The real-time bullet screen is refreshed and played on the bullet screen layer based on the three-dimensional coordinates.
