This guide teaches how to integrate Oculus Quest and create a drag-and-drop solution for Agora real-time live video streaming, which has subsecond latency global network support. The process involves installing necessary assets from the Unity Asset Store, modifying project settings, creating a scene using an existing Oculus room template, creating a new material, and making an Agora Drag And Drop prefab instance. Lastly, testing on device is done by building and running the app on an Oculus Quest headset.
