1. Can we add a video player switch button to the control video interface for players to select themselves?
  2. After clicking clear screen in the control video interface, play the default video link of the player.
  3. In the case of multiple videos, add a default video sound setting for the same scene, without conflicting with other video sounds, or set floors in the scene. When players reach a specific floor height, play the video and sound of the same floor by default.
