Abstract: A method for controlling virtual reality (VR) video playing and an apparatus are provided. In this method, a video server device renders a jump icon in a video image. When a user wants to perform video jump based on video content, a jump icon corresponding to a scene in which the user is interested may be selected to form an input. The video server obtains, based on the input of the user, a jump time of a jump target video corresponding to the jump icon, and plays the jump target video for the user from the jump time. The jump target video may be a video that is being played, or may be another video. According to the application, a video can be switched based on preferences of the user
